Why Does Septic Tank Have An Air Compressor? (Perfect answer)

An aerator, or air pump, pushes air and oxygen into your septic system. The additional oxygen increases natural bacterial activity within the system, that then provides additional treatment for nutrients in the effluent.


  • Aerobic septic tank systems utilize an air compressor or blower system to pump air into the main treatment tank. Here, the air mixes with the tank’s solid wastes and wastewater. This process is called septic tank aeration, and the oxygen in the air sustains the aerobic microorganisms which catalyze digestion of the waste.

What does the compressor do on a septic system?

Air pumps, also known as an aerators or air compressors, are critical to the function of an aerobic septic system. These products supply oxygen to the bacteria in the septic system.

Is an aerator necessary for a septic tank?

An aerator helps to push air into your septic system. Research has shown that when the air is introduced into the septic system, the air helps to break up waste faster. It also helps to give the good bacteria in your tank air that they need to survive, help them to thrive, and break up waste quickly.

Should a septic tank aerator run all the time?

The aerator should run 24/7. It should continuously provide much-needed oxygen inside the septic tank of an aerobic system. The aerobic bacteria need air to survive.

How often should a septic tank 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 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.

What is the purpose of aeration tank?

The biological treatment of the wastewater takes place in the aeration tank. Before the wastewater gets to this tank, it is mixed with activated sludge. This contains countless microorganisms, such as bacteria, that are able to break down the colloidal, organic contaminants dissolved in the wastewater.

What is the difference between an aerator and a septic tank?

Aeration systems usually will have a septic tank or “trash trap” as the first treatment of the sanitary waste from the home. Therefore, sometimes the secondary treatment behind an aeration tank will be smaller in size because of the expectation of the water to be cleaner and easier for the soil to dissipate.

How long does it take a septic aerator to work?

Most systems respond rather quickly, say within 4 weeks. The system will be fully functional during this period.

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 you maintain an aerobic septic system?

Here are the dos:

  1. Regularly Inspect Your Septic System.
  2. Pump Out Whenever Necessary.
  3. Be Water-wise.
  4. Use Licensed, Certified Companies.
  5. Flush Solids Down the Drains.
  6. Pour Harsh Chemicals in Your Toilets.
  7. Park Cars or Trucks on Your Drainfield or Reserve Area.
  8. Add Septic Tank Additives.

What is a aerobic septic system?

Aerobic septic systems are systems that use mechanical parts to treat wastewater and emit treated wastewater into the absorption field. Aerobic systems use aerobic bacteria that require pumped air to live, versus the oxygen depleted environment required for anaerobic bacteria.

Septic Air Pumps – The Lifeline of Your Aerobic System

There are numerous frequent misconceptions concerning the purpose and importance of the air pump or aerator in an aerobic septic system, and these beliefs are addressed below. In this post, I will go into further detail about the significance of your air pump and why it is so critical that it is kept in good working order at all times, including during emergencies.


Aerobic Treatment Systems are a type of wastewater treatment that is technologically sophisticated. They are often composed of a single many chambered tank or a number of tanks with a variety of stages. These stages are often comprised of a solids collection tank (trash tank), an aeration chamber, and a settling tank, among other things. Even more advanced models include an additional four-stage disinfection stage (using chlorine or ultra-violet) that may also serve as a pump chamber. An Aerobic Treatment System is capable of processing waste and discharging water that is more than 98 percent clean and odorless.

Conventional septic systems are typically comprised of a single or two compartment tank that collects big particles while allowing liquids to pass through to a secondary treatment system for further treatment (drain field, mound system, sand filter, etc.).

You’re probably asking what all of this has to do with air pumps now that you’ve gotten a quick introduction of the two primary types of sewage systems.


In the field of wastewater treatment, aerobic treatment systems are a cutting-edge technology. These tanks are often comprised of one or more multiple chambered tanks, each having a number of stages. Solids collection tanks (waste tanks), an aeration chamber, and a settling tank are often used in this process. A fourth stage for disinfection (Chlorine or Ultra-Violet) is included in most systems, which may also serve as a pump chamber. Waste may be processed by an Aerobic Treatment System, which can release more than 98 percent pure and odorless water.

In most cases, conventional septic systems are comprised of a single or two compartment tank that serves to collect big particles while allowing liquids to pass through to a secondary treatment system (drain field, mound system, sand filter, etc.).

If you have read thus far and have a basic understanding of the two most common septic systems, you may be asking what this has to do with air pumps. I’ll tell you what I think.


In many ways, the septic air pump is the lifeline of your aerobic system. It is impossible for the system to function properly unless the air pump is operating properly. Two distinct functions serve as the basis for the air pump’s operation. Firstly, the air pump introduces oxygen into the water, allowing Aerobic bacteria to colonize and survive in the water. The Aerobic bacteria in the tank are responsible for completely decomposing all of the waste. When compared to the anaerobic bacteria present in a traditional septic system, these bacteria are far bigger and more efficient at digesting waste.

Second, the air pump provides an action in the tank that breaks down big solids into little particles, making it very simple for bacteria to cling to and consume the waste, resulting in a cleaner tank.

It is the absence of a secondary treatment system behind your aerobic system, as is the case with a traditional anaerobic septic system, that poses the greatest risk of this occurring.

Raw sewage dumping into a ditch, lake, or pond, or being sprayed on your grass, as you may be aware, is not a nice thing.


Another common myth is that because the air pump just adds air to the water, it doesn’t matter what size is utilized. This is not true. It’s impossible to imagine something more far from the truth. The sizing of your air pump is really quite crucial to the performance of your system, and not every system will need the same size air pump as another. If you have visited our website, you are already aware that we provide a wide range of products in a variety of sizes and shapes. It is customary for the size of the air pump to be dictated by the volume of the tank, the kind of air diffusers installed in the tank, and the number of GPD (Gallons Per Day) that the system is meant to treat.

In most circumstances, we just require either the model number of the pump you are replacing or the brand and GPD rating of your aerobic system in order to assist you.

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 live and what state you live in, an aerated septic system is referred to by a variety of different 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:

  1. 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
  2. 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?

Aerobic Treatment Unit Aerator Pump Requirements

  • In home aerobic septic systems, diaphragm type aerator pumps are likely the most extensively utilized form of aerator pump. Linear air pumps, which are used in aerobic septic systems, compress and pump air using a diaphragm or pistons. Brands such as HiBlow, Medo, and Thomas, as well as Cyclone, Secoh, and Alita air pumps, are examples. rotary-vane air conditioning Pumps for aerobic septic systems that employ spinning carbon steel vanes to compress the air are known as compressor air pumps. Durable, requires more power, and is noisier than linear air pumps. Regenerative Blowers for aerobic septic systems are utilized on Hoot septic systems, Fast septic systems, and Bio-Microbics systems, among other types of systems. These pumps are often controlled by a timer, which allows them to be turned on and off as needed. They do not run continually
  • Instead, they run intermittently.

Typical Aerobic Septic Air Pump Capacity Ratings

The output of aerobic septic air pumps is measured in cubic feet per minute (CFM) or liters per minute (LPM) of air flow. A common septic aerator pump may provide 5 CFM (80 LPM) of air output, which is normal. The normal flow rate of septic air pumps for residential septic systems is around 2 to 8 cfm, or approximately 40 to 200 LPM of air flow rate. There is, in fact, something difficult to grasp about these evaluations. In fact, when the output is restricted, as in a septic tank, a septic air pump rated for 100 LPM air output at “open flow” (or un-restricted output) would actually give a lower flow rate than when the output is unrestricted.

Question: How do I size the correct aerator pump for my ATU?

11/5/2015 Josh asked:How can I determine the proper size of an aerator pump for my ATU? My system has a capacity of 600 gallons. We have 5 individuals living in our home, with visitors occasionally numbering as high as 10. Is it necessary to have two pumps, or may I operate them in parallel?

Reply: aerobic septic pump sizing table

Josh I’m sorry, but I don’t have an answer to your very fair question. All of these factors add up to “consult with your aerobic septic designer or aerobic pump sales or supplier contact” when determining the necessary aerator pump size or cubic feet per minute of air supply required:

  • The intricacies of how your particular system was constructed, which vary depending on the company and model you have
  • Average and maximum daily wastewater flow into the septic system
  • The size of the septic tank
  • The design of the actual aerator or bubbler
  • The distance from the aerator pump tank
  • The size or diameter of the piping
  • The length and limits such as the number of elbows
  • And other factors. because of the depth of the bubbler, which is a measure of how far the aerobic pump must drive air down and hence how much pressure the aerobic pump will meet

Intricacies of how your individual system was developed, which vary depending on the manufacturer and model; Water flow rates into the septic system, including average and maximum daily wastewater flows; the septic tank’s capacity; the actual aerator or bubbler’s design; the distance from the aerator pump tank; pipe sizes or diameters, length; and constraints, such as the number of elbows; because of the depth of the bubbler, which is a measure of how far the aerobic pump must drive air down and hence how much pressure the aerobic pump will meet.

Notes to the table above

Cfm is an abbreviation for cubic feet per minute. gpd is an abbreviation for gallons per day in the United States. lpd = litres per daylpm = liters per minute (or litres per minute in the United Kingdom) We recommend that you verify that the aerobic pump you choose has been authorized by the NSF (National Small Flows) for use with your system before purchasing it. You may get a more exact estimate of your daily wastewater consumption fromSEWAGE FLOWDESIGN FLOW ESTIMATESand then return to this page by using the “back” button on your browser.

It is recommended that you consult with the designer or manufacturer of your individual aerobic septic system since the manufacturer’s parameters may differ from those included in this general table.

Making this change alone, without making other critical design changes such as adding outlet filters or a settlement chamber, may agitate the sewage in the septic tank, causing solids to flow into the septic drainfield or absorption bed, resulting in the clogging of the drainfield or absorption bed and the rapid destruction of the system.

Aerobic Septic System Air Pump Specifications

2017/09/21 In response to Dexter’s question, “How do you check the air pressure on a pump to ensure that your diffuser is not clogged?” and “What should the air pressure measurement be?”

Reply: aerobic septic air pumps are rated as open flow in CFM or LPM but air pressure readings can be diagnostic

Thank you for your inquiry, Dexter. If you’re wondering what the optimal air output for an aerobic septic system air pump should be, there isn’t a single “correct answer” (also referred to as septic aerator pump or septic diffuser pump, or septic air pump or septic “compressor” pump). This is because, based on the size of the septic tank and the amount of waste produced on a daily basis, the pump model will be selected to meet a certain output rate. A septic air pump’s rating is often determined by water pressure rather than air pressure, because the pump’s output end is meant to be exposed to water and ultimately the atmosphere.

Another way to say it is that, although though the aerobic air pump has a pump operating air pressure capacity, the pump output is often given by the manufacturer as “open flow” capacity in cubic feet per minute (CFM) (or LPM).

That is why I stated that it is difficult to quantify.

What Air Pressure Could be Seen at a Septic Air Pump?

Using the Hiblow HP-80 aerobic septic air pump as an example, the manufacturer rates the pump’s maximum airflow at 4.2 cfm (119 LPM) when the pump is operating at 0 p.s.i., and the rated air flow will be LOWER – about 80 LPM (2.83 cfm) when the pump is operating at the rated pressure of 2.13 p.s.i. when the pump is operating under actual installed conditions. As a result of the fact that unique septic air pump specifications will change among manufacturers’ brands and models even before the pump is installed, you should make a note of the precise brand and model of the pump you are using.

  • The pressure range will most likely be between 1.5 and 5 psi.
  • To put it another way, if we went underwater (I don’t want to swim beneath sewage) and went down to 30 feet, we would be at one ATM of pressure, which is approximately 14.6 psi more pressure than being on the surface of the ocean at sea level.
  • 1/6 of 14.6 psi is equal to 2.4 psi.
  • If the pressures at our magic Tee, which we inserted in the air line, were lower than the manufacturer’s specifications, the pump (or the air line) is most likely malfunctioning (or there is an air leak).

If we notice pressures rising over what the manufacturer has specified, it is possible that the diffuser has become blocked. However, skipping the tee and the pressure gauge and simply looking for bubbles is more convenient.

Question: what are the aerobic septic pump tubing or piping distance limitations?

The following illustration depicts the drop in net air flow or CFM as a function of increasing pressure in the delivery system over zero limitations at the pump output for the Secoh EL-series aerobic pumps: CFM or LPM performance curves for the Secoh EL-series aerobic pumps. – derived from Secoh, which is discussed in further detail below. 2019/02/18 Bill Grambsch wrote: “I’d want to relocate my Aeration air pump 50 feet away from my septic tank,” he explained. I have 50 feet of 1/2-inch PVC tubing as well as the electricity to run the air pump.

Do you have any difficulties or concerns?

Is there any reason why I cannot add a 50-foot air hose to the system to eliminate the noise?

Reply: keep aerobic air pump tubing or pipes as short and straight as possible or risk inadequate aerobic treatment and system failure

Bill, Thank you for presenting such a thought-provoking question: What is the impact of distance on the performance of aerobic septic tank aerators? or What is the maximum length or distance of tubing that may be used with an aerobic septic aerator pump? The Secoh EL-80 septic pump is available in a variety of versions with air supply rates ranging from 2.83 CFM to 4.23 CFM. The pump is rated as Air Flow: 80LPM or 2.83 CFM to 4.23 CFM Open Flow. The performance curves for Secoh aerator pumps given below (which were taken from the company’s sales brochure) clearly demonstrate that as the pump’s “PSI” increases, the flow rate declines.

It is vital to comprehend the concept of “open flow.” It is possible to measure open flow at the pump’s exit since there is no resistance on the pump’s side.

The following is how septicsolutions, a vendor of septic aerators, puts up the problem: It is customary for the size of the air pump to be dictated by the volume of the tank, the kind of air diffusers installed in the tank, and the number of GPD (Gallons Per Day) that the system is meant to treat.

Keep an eye out for: In practice, this implies that, assuming that your septic aerator pump was correctly sized and installed in the first place, you should not relocate it more than 50 feet away without first contacting with Secoh or the firm who built and installed your aerobic septic system.

  • Keep in mind that if the air flow rate, volume, duration, or CFM / LPM in an aerobic septic tank is insufficient, the expense might be crippling.
  • I’m sorry for not being able to provide a more precise response, such as – yes, if you use 3/4″ tubing – but, like Secoh, from my vantage point in central Mexico, I cannot see your aerobic septic installation and so have no more information about it to share with you.
  • Septic Solutions is located at 314 Center St.
  • According to Secoh, the following pipe requirements are necessary for their air pumps: PIPING: Choose tube sizes, lengths, and attachments carefully to ensure that pressure loss is kept to a minimum.
  • Using tubing with a diameter that is greater than the port on the device (inside diameter min.
  • There are no elbows and the bends are of great radius.
  • Diffusers for aeration with low air loss – For further information, please contact Secoh EasyPump at 50 West Drive, Melbourne, Florida 32904 (phone: 321-253-1999, toll-free: 1-800-225-4498, or email: [email protected]).

Other aerobic septic system aerator-air pump checks you can make

Make sure of it.

  1. The fact that the aerobic aerator pump is operational
  2. Aerator pump is providing air to the septic tank as shown by the appearance of air bubbles at the tank top inspection port
  3. This includes making sure that the aerator pump tubing or pipe is not restricted, bent, kinked, or clogged with debris. That you are completing the periodic maintenance on your aerator pump in accordance with the manufacturer’s recommendations – samples of aerobic pump maintenance and installation manuals are provided below
  4. When the pump stops operating or is turned off, certain septic air pump types incorporate an alert feature to notify you of the situation. The fact that you may leave your aerobic system without its aerator means that the system is not operating well, it is not treating sewage effectively, and the system might fail in a matter of days
  5. This is a convenient feature.

Is My Aerobic Septic System Supposed to Run All the Time?

7:00 p.m. on May 23, 2019 One of the most often asked concerns we have from our clients is if their aerobic septic system is meant to be operating all of the time. The answer is both yes and no. The vast majority of septic systems are equipped with air compressors that are continually running. Some companies, like as Norweco, do, however, provide an Aerator that is meant to operate for 30 minutes on and then 30 minutes off. The inquiry itself seems to reflect a lack of understanding of how septic systems are meant to work in their most basic form and function.

  1. Here is some information to take into consideration.
  2. The tank is normally rectangular or cylindrical in shape, and it is composed of concrete, polyethylene, or fiberglass in most cases.
  3. During the disposal process, the particles that enter the septic tank float on top of the water where they interact with beneficial bacteria and begin to decompose.
  4. Septic tanks are available in a variety of configurations, including double-compartment and single-compartment configurations.
  5. It still carries pathogens, contaminants, and organic waste despite the fact that it has undergone some treatment.
  6. Accordingly, wastewater shall not be dumped onto the ground’s surface or into any surface or ground water.
  7. The drainfield should be suitably covered with grasses or shallow-rooted plants to prevent erosion.
  8. Its capacity to function as an efficient filter may be compromised if the soil is contaminated.

Think about how frequently you use your home’s water sources, together with how long it takes for bacteria in the system to react with the solids over a lengthy period of time, and you’ll see why the system must be running at all times, not only to keep it running but to keep it running properly.

“Modad Septic Tank Aerators, Air Pumps, BlowersAir Compressors?”

The terms used above to describe the device that supplies air to the modad treatment plant are interchangeable. a. The most correct word for this device is “Air Pump,” and its role is to create a continual flow of air to the modad aeration system through a 1/2-inch PVC pipe that connects to the first chamber of the modad treatment facility. Upon entering this chamber, the pvc pipe is directed downward for approximately 5.5 feet, to within inches of the tank’s bottom, and then branches out to form a tee with numerous drilled holes, much like an aquarium aerator, to allow the air from the air pump to diffuse through the liquid sewage from bottom to top.

“Why Do Septic Tanks/Sewer Treatment plants Need Air Pumps And Aeration Systems When Septic Tanks Don’t?”

Air pumps and aeration systems are essential in all contemporary commercial and residential waste water treatment facilities (MODADS) in order to meet regulatory requirements. So, what is the rationale behind this requirement? What is the benefit of this? The reason for this is that wastewater treatment facilities equipped with an aeration system produce effluent that is around 95 percent pure water, whereas the traditional septic tank, which does not have aeration, produces water that is only 45 to 65 percent clean.

However, it is a really strong conclusion for what appears to be a relatively basic add-on to the system.

“The Septic Tank Without An Air Pump and Aeration System”

The “septic tank” is a cylindrical or square tank with only one chamber, which might be circular or square. The waste water is broken down in the septic tank by anaerobic bacteria that are found naturally in the environment. They are referred to as “anaerobic” because they breakdown sewage waste in the absence of oxygen (oxygen). The fact that these identical anaerobic bacteria are already at work in our digestive system long before they reach the septic tank should come as no surprise. (Wow, what a beautiful concept!) The anaerobic process in a septic tank breaks down sewage by hydrolysis (adding water), which starts off fermentation, which creates acetic acid, hydrogen, and carbon dioxide at the beginning of the process.

  • Of course, we, too, emit the same gases that they do as a result of the same activities.
  • So, since all of this harmless gas is being released, then the end result must be a clean water discharge.but this is far from the case.
  • Acetic acid, ammonia, and hydrogen sulfide gas are all present in the water as a result of this addition.
  • Can you image what massive volumes of water like this would do to any species that were able to survive in it.like fish, for example?!
  • You guessed it.because all of the organic debris sinks to the sludgy bottom and initiates the anaerobic fermentation process.

That sulfuric acid stench is caused by hydrogen sulfide gas. The acetic acid present in the water causes the tannin (brown) pigment to be leached from the plant material as it decomposes, resulting in the hue of the water.

“The Waste Water Treatment Plant With An Air Pump and Aeration System”

The Modad waste water treatment facilities, which include an air pump and an aeration system, are presently being used to replace all septic tanks in the state of Mississippi. The arrangement seen in the figure below is common for these plants. This tank has two chambers (although some tanks have three); the first is the Aeration Chamber, where air from the Modad air pump is directed to the bottom of the tank through a 1/2′′ pvc pipe that terminates there and releases bubbles up through small holes drilled in the pipe.

  • This is all done in order to stir and fully aerate the waste water that is being received.
  • Let us now track the route taken by the sewage on its way in.
  • In order to proceed, it is necessary to realize that the Modad Treatment Plant, like the septic tank, is an overflow system that must be avoided.
  • The inlet pipe that you see coming into the tank from the house is set up about 4 inches above the level of the waste water in the tank, as you can see in the photo.
  • By utilizing an overflow, this helps to keep the waste water level consistent.
  • As you can see, the treatment plant is always full, but it is also in a permanent condition of water moment due to the ongoing inflow of sewage water.
  • Organic particles, oils, and greases in the sewage will float to the surface and remain there until they are digested by aerobic bacteria, which will then sink to the bottom.
  • Keep in mind that every 3 gallons that enters the Modad tank equals 3 gallons that exits the Clarifier chamber output line.
  • What are the outcomes of this experiment?

The outflow water will also be oxygenated, which means it will not be detrimental to aquatic species as they exit the tank.

“It Makes Sense To Have A Waste Water Treatment Plant And To Make Sure Your Air Pump, Aerator Is Working Properly”

We have learned from the outcomes of the Waste Water Treatment Plant in Mississippi that it is wise to check that your Modad air pump and aerator are in correct operating order before using them. What methods do we use to do this, and what issues do we have with Modad air pumps, aerators, and blowers?

“What Types of Air Pumps-Aerators-blowers are there and what is the best Type of for your Modad Waste Water Treatment Plant?”

The “Mixer Aerator” and the “Rotary Blower” are two of the most ancient forms of aeration devices, both of which are seen below: Aerator for the Mixer Blower with a rotary motion It is a great aerator that produces more air than any other form of aerator, but it, like the mixer aerator to the right, suffers from the problem of having huge electric motors that consume a lot of power and are thus expensive to run on a continuous basis.

  1. As a result, they are typically set on a timer to conserve energy and run multiple on and off cycles throughout the day to save money.
  2. If you still have one of these two types of aerators in your home, it is likely that they are no longer in operation as well.
  3. As a result, the vast majority of Modad sewage treatment plant manufacturers have now certified the newest form of air pump aerator known as the “Linear Diaphragm Air Pump” (pictured below) for use in their individual treatment plants, which may be found below.
  4. It operates in the manner depicted in the accompanying animation.
  5. After this period, the plastic diaphragms get worn and need to be changed, which may be accomplished with a relatively simple kit.
  6. Ordinarily, the amount of air pumped at between 2 and 4 psi pressure is specified in Liters per minute, which is the volume of air pumped per minute.
  7. The following diagram illustrates the dimensions and weights of the various-sized pumps:

“The National Sanitation Foundation (NSF) And Certification of Aerator, Air Pumps For Modad Sewer Treatment Plants in Mississippi”

Clearly, the Linear Diaphragm Air Pump is the most effective contemporary air pump for aeration in residential wastewater treatment facilities in Mississippi, as seen above. According to NSF regulations, the National Sanitation Foundation (NSF) must approve each make and model of Modad sewer treatment plant before it can be used “legally.” The NSF is the governing body that certifies which size, make and model of air pump may be used “legally” for each make and model of Modad sewer treatment plant.

It is recommended that you examine the relevant State’s laws and requirements before proceeding.

As a result, if you do not intend to sell your home within five years or so, your decision to go with a less expensive pump may be justified.

We sell both approved and uncertified air pumps for this purpose, and we have both on hand. Having learned everything there is to know about aerated water and air pumping, click here to have a look at the air pumps we have to offer:

What is a Septic Aerator & Why are they Important in Aerobic systems?

Disclosure: This post contains affiliate links, which means that if you purchase a product after clicking on one of our links, we may receive a commission or free product from the firms featured in this post. Amazon is a good illustration of this. The purpose of this page is to explore septic aerators, including their purpose, what they do, and why some septic systems require them. You must first comprehend how septic tanks utilize microorganisms to digest waste, as well as the distinction between aerobic and anaerobic bacteria, before you can better appreciate aerators.

  1. These microorganisms are intended to lower the amount of hazardous pathogens present in effluent (processed waste) before it is discharged into the environment, according to the manufacturer’s instructions.
  2. In the absence of oxygen, anaerobic microbes thrive in the unoxygenated environment that is characteristic of traditional septic systems.
  3. In this case, the use of aeration is necessary.
  4. By adding an aerator to your typical septic system, you may turn it into a small-scale wastewater “treatment facility.” The septic aerator pump introduces fresh air into a holding chamber in your sewage tank to help it function properly.
  5. This bacterium, in turn, degrades the wastewater, reducing the presence of hazardous pathogens and resulting in effluent that is completely safe to the environment.

A Closer Look at Aerobic Treatment Systems and the Role Aerators Play in them.

aerobic septic tank systems, according to the Environmental Protection Agency (EPA), employ aerobic microorganisms and their greater digesting ability to handle waste more efficiently than regular septic tank systems. This enables the treated effluent safe for distribution to the ground’s surface once it has been treated. Your septic system will be virtually ineffective if you do not install a septic aerator. Additionally, you may be susceptible to legal fines and penalties if you cause significant environmental harm to your local ecosystem.

An aerator system for septic tanks is normally constructed with a multi-chambered tank that has a number of phases to allow for proper air circulation.

The majority of aerator systems feature a fourth step that is required for disinfection (either chlorine or ultraviolet).

An aerobic treatment system is capable of processing waste and discharging water that is odorless and clear in more than 98 percent of cases.

In general, aerobic treatment systems will discharge surface effluent to a ditch or pond, a spray irrigation system, or a drip irrigation system, depending on the situation.

How Does a Septic Aerator Work?

In order to pump air into the primary treatment tank, aerobic septic tank systems make use of an air compressor or a blower system, respectively. The air in this tank combines with the solid wastes and wastewater in the tank. As a result of this process, which is known as septic tank aeration, the aerobic bacteria that catalyze waste digestion are able to survive on the oxygen in the surrounding air. Aerobic septic tank systems, according to the National Park Service, are capable of processing waste at rates up to 20 times quicker than regular septic tank systems, making them an excellent choice for waste processing.

Solid wastes finally make their way back to the main chamber of the septic tank from this point.

When to Use Aeration?

If there is insufficient area on your property for a drainfield provision or if your soil is inappropriate for septic drainage, the National Small Flows Clearinghouse suggests the construction of an aerobic septic system. Aerobic septic systems produce higher-quality effluent as a result of the aeration process used in them. If your property is located near a body of water that is accessible to the public or if your land serves as a source of drinking water for the general population, an aerobic septic system should be seriously considered.

The Drawbacks of Aeration

In contrast to standard septic tanks, an aerobic septic system makes advantage of the aeration process to decompose residential or facility waste considerably more quickly than it would otherwise. Because of the aerating compressor and pump, there is an increase in power demand. As a result, as compared to standard septic systems, the electrical expenses are significantly greater as well. Aerobic septic systems are constructed with a greater number of mechanical components that will require frequent maintenance and repair.

It is important to remember that if the pump is excessively powerful, the septic system aerator may cause discomfort to the waste contents of the tank, resulting in particles being flushed out to the drainfield and causing difficulties in the system.

Related Questions

The septic air pump is the lifeblood of every aerobic septic system, and it must function properly. Without a well conditioned and durable pump, the system will not perform as it was intended to. It is truly twofold in nature that the septic air pump serves: first, it pumps oxygen into the water, allowing aerobic bacteria to develop and thrive, and second, it helps to keep the water clean. As previously explained, the aerobic bacteria in the tank “eat up” or digest the waste materials that are there.

Second, the septic air pump aids in the breakdown of big solids in the tank into smaller particles, which makes it simpler for bacteria to cling to and finally eat the waste in the tank.

Your most significant problem may be that, if you have a typical anaerobic septic system, there may be no secondary treatment system to back up your aerobic system, which might be your most significant challenge.

The presence of raw sewage emptying into a ditch, lake or pond, or being sprayed onto your property’s grass, is obviously something no one wishes to happen.

Sure, septic tank systems aren’t the most interesting topics to bring up at dinner parties or cocktail hours, but they are absolutely necessary in each and every facility, whether it’s a commercial building or your own house.

Water (as well as the trash it transports) must be channeled out of your home or business and into the ever-reliable and ever-necessary septic tank before it can be properly treated.

Everything is just more hygienic when you have a septic system that performs its functions exactly as it is intended to perform. Check out the most recent Septic Air Pump pricing and customer reviews on Amazon.com. For a list of local septic service providers, please see our State Directory.
