Biological process in a septic tank Oxygen enters the water through two natural processes: Diffusion from the atmosphere. Photosynthesis by aquatic plants.
- When the electric motor is turned on by a timer, air (oxygen) is forced into the tank and the propeller stirs up the sewage and ADDS the oxygen to the sludge. The bacteria in the tank THRIVES in the presence of this oxygen and rapidly works to consume and decompose the solid waste in the septic tank.
Does a septic system need oxygen?
Your septic system removes waste through two types of bacterial activity – anaerobic digestion (does not need oxygen) and aerobic digestion (needs oxygen).
Is there oxygen in septic tanks?
Septic tank: a primary treatment system that operates in an anaerobic mode, that is, with anaerobic bacteria that operate in an oxygen free environment.
How does a septic tank breath?
A Septic Tank’s Vent The tank and its plumbing system are sealed, which means the air inside is trapped. However, as the tank fills with waste and water run-off, the air needs somewhere to go – otherwise, the pressure it creates will halt the flow of waste and back up the toilets, etc.
How often should a septic aerator run?
1 Answer. The aerator should run 24/7 nonstop and should not cost more than 10 dollars a month to run. If you electric bill is high something else is causing it or the system is not correctly hooked up.
How do I know if my septic is aerobic?
The basic difference between aerobic and anaerobic septic systems is the presence or absence of oxygen. Traditional anaerobic septic systems operate in underground tanks and in the relative absence of oxygen. This means that the bacterial colonies that break down sewage must be able to live without oxygen.
How often should aerobic septic sprinklers go off?
All aerobic systems are required to be checked every 4 months per TCEQ regulations, even if your county doesn’t require a maintenance company to perform the service (there’s a lot more to servicing your system than just adding chlorine, not to mention the health risk of coming into contact with wastewater).
What does bleach do to a septic tank?
When household chemicals get introduced to your septic tank, it kills the live bacteria inside that is needed to break down and treat the waste properly. Once the chemical or bleach kills the bacteria, it causes “die-off” and it builds up in the septic tank with nowhere to go.
Is oxygen bleach safe for septic systems?
Drain cleaner, even septic-tank safe products, should be used sparingly to avoid damage to your septic system. Vinegar (white vinegar and apple cider vinegar), Borax, OxiClean, and baking soda are some products that can be used to clean very well and be septic-system safe.
How much bleach can a septic system handle?
But, misuse and overuse of Bleach may be killing them off. Moderate use of bleach will not throw your septic system out of balance. Moderate use is the amount used in one normal size load of laundry ( 3/4 cup ) or the amount used in an application of toilet bowl cleaner.
Do septic tanks need venting?
The bacteria active in a septic tank are anaerobic. Anaerobic means the bacteria operate without oxygen from the air. There is not a great deal of gas generated in a septic tank, but the gas must be released so pressure does not build up in the tank. If the septic tank has inlet and outlet baffles, they must be vented.
How do you stop a septic tank from smelling?
Avoid pouring fats, oils, coffee grounds, cleaning products, paints, or other chemicals down your sink or tub drains. These can disrupt sewage breakdown inside the tank and cause a foul odor. Adding a cup of baking soda to a sink drain or toilet once a week will help maintain the correct pH level in the septic tank.
Should a septic tank be airtight?
Septic tanks need to be watertight. The riser should be sealed to the top of the tank and the riser cover should be sealed to the riser with butyl rubber or some other flexible sealant. No liquid should enter or leave the tank.
Does septic aeration really work?
The biggest benefit to a septic tank aeration system is that studies have shown aeration can help break up waste up to 20 times faster than good bacteria alone. All in all, this means that you will have to pump your tank less frequently and you will need a smaller size leech field for your tank.
Why is my septic tank humming?
Humming: This is a common sound when the pump is running, but if the noise is constant, then the system might be running without actually moving any water. A common cause for this is the lack of a relief hole between the pump and the check valve, which will develop an air lock in your system.
How do I know if my aerator is working?
The surest sign your aerator has failed is an overwhelming unpleasant odor coming from where your system discharges, whether into a secondary treatment system or directly into the environment.
Two Roles of Oxygen in Your Septic System – Septic Maxx
All the components of your septic system, including the bacteria, oxygen, water, sediments, plumbing and drain field (among other things), must work together in perfect harmony in order for it to function properly. If even one of these crucial components fails, it could result in thousands of dollars in septic system repairs being required. Oxygen is one of the most vital components in the body’s functioning. It aids in the regulation of bacterial development, as well as the process of breaking down solids, among many other functions.
1 Bacteria Regulation
The presence of oxygen in your septic system aids in the management of bacteria. If the oxygen level in your system becomes dangerously low, it may be required to aerate your tank. Aeration is the practice of adding more oxygen into your septic system to improve its performance. Making sure that your septic tank has the proper quantity of oxygen will assist to guarantee that the bacteria that require oxygen to survive do not perish. In order for your septic system to work properly, these oxygen-consuming bacteria must be present because they break down slime that naturally forms in your tank over time.
If the slime accumulates for an extended period of time, it might impair the soil’s capacity to absorb rainwater, resulting in an overflow of your septic tank.
2Drain Field Maintenance
The presence of oxygen in your drainfield is also important in preventing it from being blocked. This occurs when the oxygen-rich water from your tank rushes out of your tank and via the drainfield pipes in your drainfield. The movement of water transports a large number of microorganisms with it. These bacteria flourish in an atmosphere with plenty of oxygen. By moving through your drainfield pipes, bacteria assist in breaking down any leftover sediments or slime before they have the opportunity to develop a clog or become a blockage.
If your system stops operating, it could be because the oxygen balance has moved.
Septic Tank Aerator Information
When it comes to preventing your drainfield from being blocked, oxygen is also important. If your tank’s oxygen-rich water drains out of it and into your drainfield pipes, this will occur. Several germs are carried by the current of water. Bacteria like this flourish in an atmosphere with plenty of oxygen By moving through your drainfield pipes, bacteria assist in breaking down any leftover sediments or slime before they have the opportunity to develop a clog. In certain cases, if your septic system stops operating, it may be due to a shift in the oxygen balance, which results in fewer bacteria, more sediments, and a greater possibility of blockages.

What’s Your Dissolved Oxygen?
Sara Heger, author of the book, holds a sample at a test site demonstration. How do you troubleshoot a septic tank? If so, is the ATU or a media filter operating correctly? When diagnosing performance, it is critical to check the concentration of dissolved oxygen. It is possible to detect the amount of dissolved oxygen (DO) present in wastewater by measuring the amount of oxygen present. Department of ozone (DO) levels are measured in milligrams per liter (mg/L) or parts per million (ppm) (ppm).
- The phrase aerobic refers to an environment in which molecular oxygen (free oxygen, O 2) is present, or a biological activity that occurs exclusively in the presence of molecular oxygen (free oxygen, O 2).
- Essentially, anaerobic conditions are those in which all elements of wastewater and/or effluent are in their reduced state, indicating that there are no oxidants present.
- When it comes to septic tanks, however, the normal value for dissolved oxygen (DO) is less than 1 mg/L.
- Environments containing free oxygen are not conducive to the growth of anaerobic microorganisms.
- The efficiency of the anaerobic bacteria increases as the system grows.
- It is possible to attain higher removal rates of biochemical oxygen demand (BOD) and total suspended solids (TSS) in an anoxic environment.
- Organisms living in anoxic environments have the ability to utilise nitrate as an electron acceptor, releasing nitrogen in the form of nitrogen gas or nitrogen oxides as a result of this process.
A high organic content in the wastewater might potentially be a contributing factor to low DO.
This is due to the fact that the bacteria already present in the system require more oxygen in order to break down the increased amount of food.
Another possibility is that a considerable volume of dead microorganisms in the system as a result of a chemical disturbance will result in an elevated DO level.
High levels of DO can also exist in an anoxic tank if the recirculation rates are very high, as previously stated.
Avoid adding oxygen when measuring for DO, because the sample procedure may become incorrect, resulting in false results from the instrument.
Because of the same reasons, avoid sampling in close proximity to a pump. When using advanced treatment units, check with the product maker and/or designer to ensure that the right sample site and expected levels are specified. Test Kits are available for purchase.
- The range of CHEMetrics easy snap-and-read test kits, which are assessed by color comparison, is 0 to 12 mg/L (micrograms per liter). There are two kits available: one that covers the range of 0 to 1 mg/L, which is good for testing septic tanks, and another that covers the range of 1 to 12 mg/L, which is suitable for testing advanced treatment units. It costs around $55 to purchase a Winkler technique kit, which includes entirely filling a sample vial with water (no air is left to bias the test). Afterwards, the DO is “fixed” using a series of chemicals that combine to generate an acid compound that is then titrated. Winkler technique DO field kits are quite affordable, especially when compared to the cost of a meter and probe combination. Field kits are available for purchase for $35 to $200, and each kit contains enough chemicals to conduct 50 to 100 DO tests. Replacement reagents are affordable, and you may get them pre-measured for each test in plastic pillows, saving time and money. It is usual for the values to range from 0 to 12 mg/L.
Measuring Instruments and Probes Dissolved oxygen meters are electrical devices that translate signals from a probe that is submerged in water into useful information. Temperature is measured by the majority of meters and probes. Using a salt solution as a filler, the probe is fitted with a selectively permeable membrane, which allows DO to flow from the stream water into the salt solution. The DO that has diffused into the salt solution alters the electric potential of the salt solution, and this change is sent to the meter by way of an electric wire, which translates the signal to milligrams per liter of salt solution.
- Meter/probe combos cost between $500 and $1,200, which includes a lengthy cable that connects the probe to the meter and the meter itself.
- In addition, you may continuously monitor the amounts of DO at a certain spot.
- But since they are more delicate than field kits, DO meters can be quite expensive to repair after they have been damaged.
- It is possible that a corporation will just have one meter/probe due to the high cost.
- With a field kit, many members of the team can sample at the same time.
- She has presented at several local and national training events on topics such as the design, installation, and administration of septic systems, as well as research in the related field.

FAQs About Septic Tank Aerators
It’s possible that you’ve recently moved into a home that has an aeration system or an aerated septic tank, or that you’re looking to install a new ATU to repair your current septic system, that you’re looking for answers aboutseptic tank aerators. If this is the case, you’ve come to the right place. Depending on where you reside and what state you live in, an aerated septic system is referred to by a variety of various names: Aerobic Treatment Unit (ATU), aeration system, septic aerator, advanced onsite treatment unit, and other terms are used to describe these devices.
The septic tank aerator is sometimes the sole moving item in the whole system.
As a result, you want to make certain that it is constantly working smoothly and that it is regularly maintained. Continue reading for answers to frequently asked questions about septic aerators:
- What is a septic tank aerator and how does it work? An aerator, also known as an air pump, is a device that forces air and oxygen into your septic system. When there is an increased amount of oxygen available to natural bacteria in the system, this improves the amount of treatment that can be provided for nutrients in the effluent. Air is drawn into the tank by an aerator system from the outside and pumped through the tank by a pipe network and diffuser that are located inside the tank. What are the advantages of installing a septic aerator? There are several advantages to this system, including the fact that it can be used in homes with smaller lots, inadequate soil conditions, in areas where the water table is too high, and in homes located near a surface water body that is sensitive to contamination by nutrients contained in wastewater effluent. ATUs should be maintained on a regular basis during their service life. How difficult is it to keep a septic tank aeration system running? As with any onsite septic system, you will need to pump your tank every 3-5 years, as is standard practice. Always be cautious of what you put into a tank that has an aeration system
- The Think at the Sinkbrochure from the EPA SepticSmart program is a fantastic resource for guidance. As the moving parts of your aerator near the end of their service life, you will need to repair or replace them as necessary. Always use authentic manufacturer certified components for any repairs, as aftermarket parts may invalidate any warranties and may not be able to withstand the stresses placed on your system as a whole. If your aerator is of a certain size, the ambient temperature in your location, whether or not your in-tank diffusers require cleaning, and how your pump is installed will all influence how long it will last. Which HIBLOW air pump do I need for my septic system and how many do I need? Please check with the manufacturer of your overall treatment system to confirm that the air pump is the proper size for your particular unit. Another advantage of using a professional service provider is that they can help you select which HIBLOW pump type you require. Where can I get repair kits for my air pump?

Contact HIBLOW for Septic Aerators!
Exactly what is a septic tank aerator, and why do you need one? Air is pumped into your septic system by an aerator, which is also known as an air pump. Due to the increased natural bacterial activity inside the system, the system can handle more nutrients in the effluent as a result of the higher oxygen supplied. Inside the tank, there is an aerator system that sucks air in from the outside and circulates it throughout the tank via a pipe network and diffuser. A septic aerator has a number of advantages.
- ATUs should be subjected to routine life-cycle maintenance.
- As with any onsite septic system, you will need to pump your tank every 3-5 years, as is standard procedure.
- The Think at the Sinkbrochure from the EPA SepticSmart program is an excellent resource.

How Does a Septic Tank Work?
Mr. Fix-It-Up-For-The-Family You may save a lot of money if you understand how a sewage treatment system works—and what can go wrong—so that you can handle your own septic system maintenance.
How does a septic tank work?
Pumping the tank on a regular basis eliminates sludge and scum, which helps to keep a septic system in good working order. It is possible for a well-designed and well built septic system to last for decades, or it might collapse in a matter of years. It is entirely up to you as long as you can answer the question of how do septic tanks function. Healthy septic systems are very inexpensive to maintain, but digging up and replacing a septic system that has completely collapsed may easily cost tens of thousands in labor and material costs.
It’s critical to understand how a septic tank works in order to maintain one.
Let’s take a look below ground and observe what happens in a properly operating septic system, shall we?
Understand that a septic system is a cafeteria for bacteria
Bacteria are responsible for the proper operation of a septic system. They decompose garbage, resulting in water that is clean enough to safely trickle down into the earth’s surface. The entire system is set up to keep bacteria healthy and busy at all times. Some of them reside in the tank, but the majority of them are found in the drain field. 1. The septic tank is the final destination for all waste. 2. The majority of the tank is filled with watery waste, referred to as “effluent.” Anaerobic bacteria begin to break down the organic matter in the effluent as soon as it enters the system.
- A layer of sludge settles to the bottom of the container.
- Scum is mostly constituted of fats, greases, and oils, among other substances.
- Grease and oils float to the surface of the water.
- (5) A filter stops the majority of particles from reaching the exit pipe.
- The effluent is discharged into the drain field.
- Effluent is allowed to leak into the surrounding gravel because of holes in the drain septic field pipe.
- The garbage is completely decomposed by aerobic bacteria found in gravel and dirt.
- Potable water seeps into the groundwater and aquifer system from the surface.
Septic Tank Clean Out: Don’t abuse the system
Septic systems that have been correctly planned and constructed require just occasional ‘pumping’ to remove the sludge and scum that has built up inside the tank.
However, if you don’t understand how a septic tank works, you may unintentionally hurt or even destroy the system.
- Drains are used to dispose of waste that decomposes slowly (or not at all). Cigarette butts, diapers, and coffee grounds are all known to cause issues. Garbage disposers, if utilized excessively, can introduce an excessive amount of solid waste into the system. Lint from synthetic fibers is emitted from washing machine lint traps. This substance is not degraded by bacteria in the tank and drain septic field. Bacteria are killed by chemicals found in the home, such as disinfecting cleansers and antibacterial soaps. The majority of systems are capable of withstanding limited usage of these goods, but the less you use them, the better. When a large amount of wastewater is produced in a short period of time, the tank is flushed away too quickly. When there is too much sludge, bacteria’s capacity to break down waste is reduced. Sludge can also overflow into the drain field if there is too much of it. Sludge or scum obstructs the flow of water via a pipe. It is possible for tree and shrub roots to obstruct and cause harm to a drain field. Compacted soil and gravel prevent wastewater from seeping into the ground and deprive germs of oxygen. Most of the time, this is caused by vehicles driving or parking on the drain field.
Get your tank pumped…
Your tank must be emptied on a regular basis by a professional. Pumping eliminates the accumulation of sludge and scum that has accumulated in the tank, which has caused the bacterial action to be slowed. If you have a large tank, it may be necessary to pump it once a year; but, depending on the size of your tank and the quantity of waste you send through the system, you may go two or three years between pumpings. Inquire with your inspector about an approximate guideline for how frequently your tank should be pumped.
…but don’t hire a pumper until you need it
Inspections and pumping should be performed on a regular basis. However, if you’re not afraid of getting your hands dirty, you may verify the sludge level yourself with a gadget known as The Sludge Judge. It ranges in price from $100 to $125 and is commonly accessible on the internet. Once you’ve verified that your tank is one-third full with sludge, you should contact a professional to come out and pump it out completely.
Install an effluent filter in your septic system
Inspections and pumping should be performed on an ongoing basis. The Sludge Judge is a device that allows you to examine the level of sludge in your own home if you are not afraid of heights. There are several internet retailers who sell it for $100 to $125. In the event that you discover that your tank is one-third full of sludge, contact a contractor to come pump it out for you.
Septic tank filter close-up
The need of regular inspections and pumping cannot be overstated. However, if you are not afraid of being queasy, you may verify the sludge level yourself using a contraption known as The Sludge Judge. It costs between $100 and $125 and is easily accessible on the internet. You should contact a contractor as soon as you realize your tank is one-third full with sludge.
Solution for a clogged septic system
If your septic system becomes clogged and you find yourself having to clean the filter on a regular basis, you might be tempted to simply remove the filter altogether. Hold on to it. Solids, wastewater, and scum are separated into three levels in septic tanks, which allows them to function properly (see illustration above). Solids sink to the bottom of the container, where microbes breakdown them. The scum, which is made up of trash that is lighter than water, rises to the surface. In the drainage field, the middle layer of effluent leaves the tank and goes through an underground network of perforated pipes to the drainage field.
- Keep the effluent filter in place since it is required by your state’s health law.
- Waste particles might flow through the filter and clog the perforated pipes if the filter is not used.
- Your filter, on the other hand, should not require cleaning every six months.
- A good chance is high that you’re flushing filter-clogging things down the toilet, such as grease, fat, or food scraps.
- A garbage disposal will not be able to break down food particles sufficiently to allow them to flow through the septic tank filtration system.
- Plastic items, disposable diapers, paper towels, nonbiodegradable goods, and tobacco products will clog the system if they are flushed through it.
For additional information on what should and should not be flushed down the toilet, contact your local health authority. More information on removing lint from your laundry may be found here.
Get an inspection
Following a comprehensive first check performed by an expert, regular inspections will cost less than $100 each inspection for the next year. Your professional will be able to inform you how often you should get your system inspected as well as how a septic tank functions. As straightforward as a septic system appears, determining its overall condition necessitates the services of a professional. There are a plethora of contractors who would gladly pump the sludge out of your tank, but many, in my experience, are unable to explain how a septic system works or how it should be maintained.
A certification scheme for septic contractors has been established in certain states; check with your state’s Secretary of State’s office to see whether yours is one of them.
Also, a qualified inspector will be able to tell you whether or not your tank is large enough to accommodate your household’s needs, as well as the maximum amount of water that can be passed through it in a single day.
As you learn more about how a septic tank works, your professional should be able to tell you whether or not your system will benefit from this treatment.
Alternatives to a new drain field
If an examination or a sewage backup indicate that your drain field is in need of replacement, the only option is to replace it completely. As a result, it’s important to talk with a contractor about other possibilities before proceeding with the project.
- If an examination or a sewage backup indicate that your drain field is in need of replacement, the only option is to replace it completely. A contractor should be consulted about alternative possibilities because the costs might be quite expensive.
Protect your drain septic field from lint
When this device is in place, it inhibits lint from entering the system, especially synthetic fibers that bacteria are unable to digest. One of these filters, which I’ve designed and termed theSeptic Protector, was invented by me. An additional filter is included in the price of around $150 plus delivery. Learn more about how to filter out laundry lint in this article.
Don’t overload the septic system
Reduce the amount of water you use. The volume of water that flows into your tank, particularly over a short period of time, can be reduced to avoid untreated waste from being flushed into your drain field. Replace outdated toilets with low-flow ones, install low-flow showerheads, and, perhaps most importantly, wash laundry throughout the week rather than just on Saturday mornings to save water.

WASTE NO TIME LEARNING TO CARE FOR SEPTIC TANK
Q-I recently acquired a property that included a septic tank. What should I do now? All of my prior residences were serviced by municipal sewer systems. What in the world is going on with these things? Is it necessary for me to be worried about what I dump down my drains? Is there a need for maintenance? A-Approximately 25 million households in the United States rely on these basic but extremely effective devices for waste water treatment. When properly designed, installed, and maintained, they perform an excellent job of safeguarding both the environment and the health of your family’s surroundings.
- The majority of the time, waste water from your home is transported to the septic tank by gravity.
- Bacteria in the tank begin attacking and decomposing the waste very soon after being introduced.
- Septic tanks take on a layered appearance.
- The partially treated waste water is released from the tank after one or two days of treatment.
- The waste water is now sent to the drain field, which is comprised of a network of interconnecting pipes that are laid in sand or gravel-filled ditches to collect the water.
- After passing through the holes, the waste water is absorbed by the soil, which serves as a biological filter.
- Septic tanks must be large enough to handle the amount of people that live in the house they are installed in.
Solid particles as small as a grain of sand or a grain of gravel are conveyed into the drain field, where they might accumulate and clog the sand, gravel, and soil filters.
In both cases, the conditions are unclean and constitute a major threat to public health.
Reduce the amount of solid particles and scum-forming substances that enter the system.
Keep an eye out for chemicals or solvents that might harm the beneficial microorganisms in your tank.
The last point to remember is to get your sewer system checked annually and pumped clean on a regular basis.
If it makes its way into the drain field, you will be faced with a significant repair price.
As a result of the oxygen, their proliferation is encouraged, and more bacteria means a faster breakdown of waste particles.
Do this twice a week, and your septic system will silently thank you for your efforts.

How Aeration Systems Work
When it comes to sewage treatment systems for the home, there are two main types of designs to choose from: septic and aerobic. Both of these devices are used to begin the process of cleaning wastewater before it is sent to a secondary treatment facility. According to the characteristics of your property and the requirements of your family, anaerationsystem may be a far superior option.
How Anaerobic Septic Systems Work
An anaerobic environment is created in the septic tank (which implies that there is little or no oxygen dissolved in the water), in which heavier materials sink to the bottom and lighter fats and oils ascend to the top, with grey water floating between the two. This technique uses bacteria to break down solid waste slowly, allowing relatively “clean” grey water to pass into a drain field. This system is designed to hold wastewater in the septic tank for approximately 24 hours before it is released into the drain field, which is why excessive water use (such as doing all of the laundry for the family in one day) can overload the septic tank and have devastating consequences for your drain field.
Aeration systems are used in situations when a septic tank provides an environment with little free oxygen in the wastewater. This allows the bacteria residing in the system to break down waste solids more rapidly and efficiently than they would otherwise be able to accomplish. Aerators are devices that are used to introduce air into a sewage treatment system in order to mix and oxygenate the liquid being processed. Because of this, the solids decompose far more quickly. The system is comprised of three separate chambers that filter and cleanse the wastewater generated by your household.
After passing through this compartment, the water containing suspended particles reaches the aeration compartment, where an aerator mixes the water and provides oxygen to it.
Most of the time, the water will subsequently be sent to a smaller, secondary treatment system (like a drain field, but one that is smaller than those required by an anaerobic system).
Advantages of an AerationSystem
This technique is particularly useful if your property lacks the area required to accommodate a drain field or your soil is too dense to allow for good septic drainage, as is the case with much of Northeast Ohio’s clay-rich terrain. An aeration system is frequently employed in more urban environments, when properties are smaller in size. Additionally, when the drain field of an anaerobic septic system is beginning to deteriorate, anaeration systems are frequently constructed to provide additional oxygen.
It is less likely that your septic system will be adversely affected by excessive water use because of the effectiveness and speed with which an aerator breaks down the sediments in your tank.

Septic Tanks and Oxygen Facts
- Illusions regarding septic systems
- Actualities concerning septic systems All septic systems, including the AddStain Solverto system, require oxygen.
Many people are confused about how septic tanks function and whether it is a good or bad idea to add oxygen bleach to a septic tank, which is a common mistake. Let’s clean the tank, er, the air, of all of this muddled thinking immediately. Allow me to begin by informing you of two points up front: In my professional capacity as a master plumber, I’ve had decades of expertise working with raw sewage, septic tanks, municipal sewer lines, and everything else that goes into these systems. When I was still working in the plumbing industry on a daily basis, I had the title of licensed master plumber for more than 25 years.
- Until recently, it was the only Certified organic oxygen bleach that I was aware of that was available for purchase in the consumer sector.
- Lie number one: Septic tanks are anaerobic, which means they do not contain any oxygen, and the bacteria that live within the tank thrive in such an atmosphere.
- In contrast, waste entering a septic system enters a CONFINED SPACE with little or no access to ambient oxygen, but trash entering a sewer system does not.
- As wastewater travels through the sewage pipes to a municipal sewage treatment facility, it is exposed to oxygen and air, which helps to disinfect it.
- As the wastewater makes its way to the sewage treatment facility, the agitation helps to oxygenate it.
- Because of the way waste decomposes, methane gas is created and fills the air space above the wastewater in the tank, removing any oxygen that may have been there.
- It is not by choice that wastewater is channeled into this hole that is devoid of oxygen.
FACTS:Once again, the wastewater that enters both systems is of the same composition.
The same solid waste generated by humans.
The same gray water that comes from washing, kitchen sinks, bathroom sinks, bathing, and other sources is used.
The brand new septic tanks that are shipped to you from the concrete, plastic, or fiberglass manufacturing factory do not come pre-loaded with hidden anaerobic bacteria from the production company.
Myth 3: Septic tanks are fundamentally different from a municipal sewage system, and this is why they are anaerobic (without oxygen).
Essentially, these devices function as small sewage treatment plants.
Located on top of the tank is a motor powered by electricity.
A propeller is located at the end of the shaft.
Having this oxygen in the tank allows the bacteria in the tank to thrive, which allows them to work more quickly to devour and digest the solid waste in the tank.
A common urban legend holds that municipal wastewater treatment plants work miracles on wastewater before permitting it to flow back into the rivers where people swim, water-ski, and boat.
There is no such thing as magic.
Among the things that can be flushed down the toilet are sand, clay, plastic caps, plastic army men, and any other object that did not come out of our bodies but was flushed down the toilet.
When wastewater reaches the sewage treatment facility, it is a vile brew of foul WATER that has a distasteful hue.
It’s an absolutely wonderful video: As soon as this liquid, which is full of microscopic solid waste particles, has settled, it is delivered to the secondary treatment section of the facility.
Large spray arms can be used for secondary treatment, with the liquid waste water being pushed into them and then allowed to drop back into the massive tank.
In addition, there are systems that contain massive linear waterfalls that stir up the water and supply oxygen to the air as a result of the water splashing.
Another approach for increasing the oxygen content of wastewater at a municipal treatment facility is described here.
This additional therapy might take anywhere from a few hours to a few days.
So long as you have faith in the personnel working at the sewage treatment facility and everything is operating correctly, of course.
When storm water drains and municipal sewers are combined, as is the case in older cities, this can happen.
Myth 5: Adding BLEACH to a septic tank is really BAD for the environment.
If you use CHLORINE bleach, you are doing something really wrong.
It KILLS BACTERIA in a short period of time.
Oxygen bleach FEEDS and AIDS the bacteria in their efforts to flourish and live.
In summary, if you have a septic system and would like to HELP the bacteria in the system, you should ADD OXYGEN to your septic tank.
Stain Solver is manufactured in the United States of America using components of food-grade purity.
However, if you are unable to do so, you may simply addStain Solverto to your septic tank once, twice, or four times a month, depending on the number of people that live in your house.
My solution is to dump it down the toilet and flush it twice. It’s really that simple. My septic tank is madly in love with me. This piece was SO GOOD that I decided to share it with the 31,000 subscribers who received my AsktheBuilder Newsletter on February 25, 2018.
Life in the Septic Tank
What factors can have an impact on septic tank biology?
When it comes to pumpers and other service providers who often visit the interior of working septic tanks, one issue that comes up frequently is: Why do I see such a broad variety of conditions? Moreover, what are the possible causes of septic tanks operating in an unsuitable manner? Preceding my discussion of issues that might negatively impact the operation of a septic tank, I’ll provide a quick overview of what a properly working septic tank should look like and what should be occurring within it in terms of treatment.
BREAKING IT DOWN
When it comes to pumpers and other service providers who often visit the interior of working septic tanks, one issue that comes up frequently is: Why do I see such a broad variety of conditions? Then there is the question of what might cause septic tanks to malfunction. Preceding my discussion of issues that might negatively impact the operation of a septic tank, I’ll provide a quick overview of what a properly working septic tank should look like and what is taking place within it in terms of treatment and filtration.
UPSETTING THE SYSTEM
What might lead a tank to be “upset” and to fail to show the three separate layers is not entirely understood. As with any troubleshooting procedure, we must consider the water-use habits of the household, as well as the usage of high-water-consumption devices that prevent settling and separation from occurring in the first place. For example, washing many loads of clothes or dishes in succession can be as simple as doing so. This has the potential to both hydraulically overflow the tank and — in the case of dishwashers – add a significant amount of organic waste.
- Septic tank contents can be stirred up by hydraulic surges in either situation.
- Another issue that is comparable to this one occurs when large-volume whirlpool baths are used.
- Because of this, the water entering the septic tank is under greater pressure, resulting in turbulent flow within the tank.
- Once it has been verified that there is no problem with the flow or water usage, it is necessary to investigate the chemical items being utilized.
In other words, gas is being released around the sludge, making it buoyant and allowing it to float or be suspended. Prior to the installation of effluent screens, these sediments were frequently conveyed to the soil treatment area before anybody became aware of a problem.
CLEANING PRODUCT USAGE
Cleaning agents might have cumulative effects in the tank if they are used excessively or on a frequent basis. Antibacterial characteristics are now prominently advertised by the majority of cleansers. They also have no way of distinguishing between bacteria destroyed on the sink, toilet, or countertop and germs existing in the septic tank if they happen to be antimicrobial. The widespread use of antibacterial liquid hand soaps can also be a source of concern, as they can slow down the already sluggish anaerobic digestion process, resulting in increased sludge and scum formation and the need for more frequent maintenance.
- These are mostly relevant to the cleaning of toilet bowls.
- Homeowners should be reminded to read the labels of any cleaners that are eventually flushed down the toilet.
- If a product’s label contains the word “warning,” it signifies that only restricted usage of the product should have a negative impact.
- Toxic drain cleaners that are used to clear clogs and blockages from plumbing systems are often classified as hazardous.
- It is possible that this may result in increased FOG quantities, which, if passed on to the soil treatment area, will promote the growth of biomat, limiting the soil’s ability to receive water.
- Another area of concern is the use of prescription medications.
- Additional tank maintenance may be required in order to resolve this issue.
Aerobic Septic System, a Rundown of How They Work and Cost
Using cleaning solutions in excess or on a frequent basis might have an adverse effect in the tank. The antibacterial qualities of most cleaning products are now prominent. They also have no way of distinguishing between bacteria destroyed on the sink, toilet, or countertop and germs present in the septic tank if they do contain antibiotic ingredients. Another issue is the widespread use of antibacterial liquid hand soaps, which can impede the already sluggish anaerobic digestion process, resulting in increased sludge and scum formation and the need for more frequent cleaning.
- Toilet bowl cleaning is the key concern in this case.
- Every homeowner should be advised to check the labels of any cleaners that will be flushed down the toilet.
- Because it states “warning,” it signifies that only a restricted amount of the product should have a negative influence on your health.
- Drain cleaners that include toxic chemicals and are used to clear clogs and obstructions from plumbing systems are often classified as hazardous substances.
- This can result in increased FOG quantities, which, if carried over to the soil treatment region, can promote the growth of biomat and reduce the soil’s ability to absorb water.
- Another source of concern is prescription medications.
Increased tank maintenance may be necessary in order to resolve this issue. Further faults will be identified when we carry out more rigorous maintenance on systems in the future, and we will get a greater understanding of how to keep septic tanks working efficiently.
How does an aerobic septic system work?
There are two types of septic systems: conventional septic systems and aerobic septic systems, which are more sophisticated. The difference may be summed up in one word: oxygen. When compared to the anaerobic process, an aerobic treatment unit (ATU) employs Oxygen infusion to decompose solids and lipids instead of the anaerobic process used by a normal septic system. Like conventional (or standard) systems, an aerobic (or natural) septic system treats wastewater via the use of natural processes.
This treatment is done in stages:
- Pre-treatment can take the form of a septic tank being staged in front of the ATU, or it can take the form of an ATU having a settling or rubbish tank built inside the unit. The solids will be separated from the wastewater during this pre-treatment stage.
- Aeration Chamber – Using an air compressor or a blower, forced air is mixed with the wastewater in this chamber. This phase promotes the growth of aerobic bacteria in the wastewater, which will help in the digestion of particles present in the wastewater.
- Treatment of wastewater leaving the ATU – This phase entails adding an extra treatment step to the effluent exiting the ATU. This can include the use of chlorine or UV radiation, among other things.
- Finally, the effluent exiting the ATU is released into a drain field, which may be a sand filter, an absorption field or an evapotranspiration bed
- This is known as the final treatment disposal.
Why do we need an Aerobic Septic System?
Consider the following scenario: you wish to acquire a beautiful piece of land for a cottage, ideally located near a lake. For the time being, let us assume that the lot size is limited, but it will be sufficient for the purposes for which you have planned. Let’s take a look at why a standard septic system would not be appropriate for this sort of property: Being in close proximity to a water body might indicate that there is a high water table immediately below the surface, or at the very least that the water table is high seasonally.
When we insert an aerobic treatment unit into the system, the wastewater that exits the system is classified as type 2.
with?… Yes, Oxygen, you are well aware of the situation.
10 Advantages Of An Aerobic Septic SystemNegatives
- It provides a greater amount of wastewater treatment and may be used on poor soil types. When dealing with difficult lot sizes and restricted terrain, this product is recommended. When there are setback restrictions to property borders, open water sources, or aquifers, this is what is used. More environmentally friendly since it makes use of smaller drain field footprints. It has been demonstrated that it can extend the life of drain fields. Drain field congestion is greatly reduced as a result of this. Irrigation is beneficial for water conservation, and several states permit it. It helps to reduce nitrogen. Increases the overall performance and lifespan of the system, which helps to offset the original expenditures.
- Blower noise
- A little odor if the unit is not properly ventilated
- Increases the amount of electricity drawn
- It is not possible to avoid maintenance. Initial installation expenses that be higher
- Contamination can occur as a result of poorly maintained systems. An excessive amount of water might cause the system to become overburdened. Cold weather can have negative consequences
- Thus, it is necessary to be adequately insulated.
A little scent if the unit is not properly ventilated; noise from the blower More power is attracted. It is not an option to do maintenance. Initial installation expenses that are more than expected. Contamination can be caused by poorly maintained systems. An excessive amount of water might cause the system to become overloaded. When it is cold outside, it is important to be well insulated.
Aerobic septic system maintenance: what’s involved?
Aerobic septic systems are among the most complicated and technologically advanced systems available for waste treatment – and we now understand how they function and how they compare to a regular septic system. But what exactly is required in keeping an aerobic septic system in good working order? First and foremost, it is critical to understand how to gain access to your system in order to do the necessary tests. Most of the time, the entry points to your system will be within 10 feet of your home and at ground level.
- Having them changed if they are broken or discolored is a solid indication that they need to be replaced.
- Consequently, be certain that the gas has cleared before checking the tank.
- Keep an eye on this since identifying and correcting an issue when it is still small is far preferable than neglecting your system and allowing a problem to fester for an extended period of time, which might cause harm to the equipment.
- This is something that you may easily accomplish on your own, provided that you have double-checked the frequency and dosages mentioned in the owner’s handbook that came with your particular system before starting.
- It will, however, destroy any grass or other plants in its path.
- Then screw the cover back on.
- Observing minor problems and addressing them before they become significant issues is critical once more.
- Use of irrigation sprinkler heads is not recommended since they are incompatible with the operation of a septic system.
- Making a map of your aerobic septic system, including the access ports and spray heads, is an excellent method to keep track of the complete system, from the access ports all the way to the spray heads.
- Maintain a record of your upkeep.
- And keeping note of any services and tests conducted on your system and the dates they were completed can help you keep track of what happened when.
At least once every six months, ensure that the following things are done: the free chlorine residual of the effluent in the pump tank is tested and recorded; the depth of the sludge in the trash tank is measured and recorded; the volume of sludge in the aerobic treatment unit is measured and recorded; and a clarity test is performed and the results of this test (pass or fail) are recorded; and And keep in mind that everything that goes down the sink will end up in your septic tank.
Dental floss, bandages, condoms, feminine hygiene products, cigarette butts, and kitty litter are just a few of the terrible items that have made their way into septic systems through domestic toilets throughout the years.
Keep in mind that you have buddies down there: pouring dangerous chemicals and cleansers down the drain will kill the microorganisms and bacteria that reside within your system and prevent your wastewater from being properly treated by the system.
As a result, do not flush liquids down the toilet such as drain cleaners, insecticides, varnishes, thinners, or paints.
Finally, understand when it’s necessary to bring in a maintenance specialist.
A properly operating septic system ensures that your house runs smoothly and that your family remains healthy.
How much does an aerobic septic system cost?
Aerobic septic systems are more sophisticated than regular systems, and as a result, they are also more expensive than standard systems. The benefit of an aerobic septic system is seen in the quickness with which it can be installed and the advanced level of treatment that it can provide. Our systems and services are expected to cost the following amounts, according to our estimates: We can estimate expenses in British Columbia, Canada, based on a number different systems, including:
Type 2 Septic System costs using an ATU with aeration and drain field:
- Gravity or traditional septic systems, as well as the utilization of a uniform distribution system in conjunction with drain field technology to obtain a type 2 system, can cost between $20,000 and $30,000 to construct. In order to attain a type 2, an ATU septic system installation can cost anywhere between $25,000 and $35,000
- However, this is not always the case. Depending on the geography, the cost of using an ATU in conjunction with a subsurface drip line might range from $25,000 to $35,000. The cost of using an ATU in conjunction with an Evotranspiration bed is between $25,000 and $40,000, depending on the home’s size.
In the case of a Type 3 septic system, which requires an additional disinfection unit in addition to the aeration unit, we may estimate an additional cost of $10,000 to $15,000 beyond the previously examined cost points. More information on determining the cost of a septic system may be found here: Design Services for a Septic Design are typically $2000 for Type 1 Gravity systems and $2500 for Type 2 Gravity systems and Pressure systems, depending on the system.
Please keep in mind that these costs will vary based on where you live in British Columbia and how easily you can get supplies.
