Why Should Grease Trap Be Used With Septic Tank? (Question)

Grease traps are used as an additional treatment component and are placed before septic tanks. They are usually required for septic systems that serve a business that produces a large amount of fats, oils and grease (FOG), such as restaurants.

  • by Karl Holt. Grease traps have long been used in restaurants and food processing plants to prevent fats, oils and grease (FOG) from entering the septic tank and, eventually, the drainfield or sewer system. When properly serviced and maintained, they are very effective at reducing FOG levels in the system.

Why is grease a problem for septic systems?

Grease. It won’t break down the way water and waste will. If you pour grease down a drain, you will end up clogging your drain and nothing will be able to get through. Clogged pipes may lead to your septic system backing up and, in turn, cause serious damage to it.

Why grease trap is required?

The purpose of a grease trap is to collect and therefore reduce the amount of fats, oils and greases (FOG’s) that enter the main sewers. Grease entering the main sewer system will over time create blockages, foul odours and pest infestation.

How do you prevent grease build up in a septic tank?

Using a grease trap additive, such as the liquid or powder form of Bio-Secure Grease Trap Concentrate, can help prevent septic tanks, grease tanks, and sewer lines from clogging. It is relatively easy to use. Just mix the power or liquid additive with warm water and rinse it down the drain.

Does sewage go through a grease trap?

The traps reduce the amount of fats, oils, greases, and solids (FOGS) that enter sewers. They comprise boxes within the drain run that flows between the sinks in a kitchen and the sewer system. They only have kitchen waste water flowing through them and do not serve any other drainage system, such as toilets.

How does grease get in septic tank?

The main reason FOG buildup occurs in a septic tank is because you are in the habit of disposing of cooking oil or grease in your home’s plumbing drain system. When the scum layer becomes too thick, it will begin to push down on the liquid waste layer, which is where the exit drains are located.

What is a septic grease trap?

Grease traps are used as an additional treatment component and are placed before septic tanks. A grease trap works by slowing down the flow of warm/hot greasy water and allowing it to cool. As the water cools, the fat, grease, and oil separate and float to the top of the grease trap.

What happens to grease trap waste?

After the grease trap is thoroughly cleaned, the grease trap cleaning company will take the waste to a treatment facility. There are a few different ways grease trap waste can be recycled. This solidified waste can be mixed with sawdust, moss and wood chips containing microbes and left to compost.

Where are grease traps required?

Grease traps/interceptors shall be installed to receive the drainage from plumbing fixtures and equipment with grease-laden wastewater located in the FSEs such as restaurants, hotel kitchens, hospitals, school kitchens, cafeterias or clubs.

What is the purpose of grease interceptor?

A grease interceptor is located between kitchen drain lines and sanitary sewer lines. Grease interceptors capture the FOG that enters sink drains from food service activities such as food preparation, dishwashing and cleaning.

Where is the grease trap on a septic tank?

So, if grease traps are vital for commercial establishments, what about grease traps for residential septic systems? Placed ahead of the kitchen sink(s) and in front of the septic tank, they could be effective at prolonging the life of households with septic systems that see high levels of FOG.

How does a residential grease trap work?

A grease trap works by cooling warm or hot greasy water. Vegetable oils and animal fats are 10 to 15% less dense than water and are insoluble in water. By allowing the fats, oils, and grease to cool, the different layers of the mixture are able to separate into individual layers for easy separation.

What is the difference between a grease trap and a grease interceptor?

Whether the unit is a grease trap or grease interceptor, the technology works the same. The difference between a grease trap and a grease interceptor is the flow rate of wastewater that the device can handle. A grease trap works well with a lower volume of flow; less than 50 gallons per minute.

How often should a grease trap be cleaned?

Most grease traps should be cleaned out every 1-3 months, depending on usage. To know exactly how often your business needs to attend to the grease traps, consider the “1/4th rule.” In simple terms, the grease trap should be cleaned out when it reaches a quarter of its capacity.

Is grease trap a solid waste?

Grease trap wastes (GTW) are normally siphoned out of traps by tanker trucks as a liquid with about five to six percent total solids content. Decanting can raise the solids content to 35-40 percent. GTW contains grease, water, sediment (mostly food particles) and contaminants that are washed down the drain.

What Is a Septic Tank Grease Trap?

There are certain changes in maintenance, usage, and budgeting that you should be aware of, whether you’re a new homeowner with an existing septic system or planning to buy or build a home without sewer hookups. Here’s what you should expect. Three ways in which your budget may be affected when your wastewater is handled by a septic system are detailed in this guide: No need to budget for city sewer service in the first place! As a result, since the municipal wastewater system often processes all of the water, the cost of city sewage service is frequently determined by how much water you purchase from the municipality.

A large number of homes with septic systems also rely on wells for fresh water rather than municipal water, which means you’ll likely save money in that area as well, as well.

It is necessary to budget for septic maintenance as well.

Annual inspections and frequent tank pumping are included in these charges, as is the possibility of an occasional repair such as a baffle replacement or tree root extraction.

  1. For example, you might create a separate budget category for septic repair and maintenance, or you could include these charges in your existing home maintenance category.
  2. Saving around one-third of the cost each year will allow you to save enough money to have your tank pumped once every few years, which is a small investment considering the frequency with which you will need to do this.
  3. 3.
  4. An average septic system may endure for up to 25 years, and in some cases considerably longer.
  5. When selling your home after the septic system has been in place for a few decades, you should be aware that the market value of your home may be significantly reduced.
  6. Despite the fact that a well maintained system can endure for 25 years or more, the operational life may be significantly decreased.
  7. If you have to replace the entire system (or at least key sections of it) because of these and other circumstances, you should be prepared to do so.
  8. If you don’t have adequate emergency cash, a septic system replacement, like any other unexpected significant cost, might leave you in debt.

What Is A Septic Tank Grease Trap?

Many people refer to the grease trap as a grease interceptor, which is another name for it. It is a device that is put in the plumbing system and is responsible for preventing grease, fat, and other oily particles from entering the sewage system. Wax, fat, oil, and other forms of debris are hindered because, once they solidify inside the tank, they will form clogs that will obstruct the otherwise smooth process of waste material degradation and filtration that is expected to take place. Plumbing problems will inevitably emerge as a result of this.

Your house will fill with a horrible, filthy odor that will make you want to puke up almost immediately.

Are Grease Traps Required To Be Installed?

It is true that they are necessary not just in commercial buildings, but also in residential constructions. Grease traps are required by building rules and must be installed. These devices ensure that scum and sewage are processed before they are discharged into a septic tank or into a public sewer system, respectively. Waste materials are processed in this manner, and oily compounds are removed from wastewater in this manner.

What Happens After The Grease Trap Installation?

Grease traps are not installed, and then they are left unattended for an extended period of time. These devices also require regular cleaning and maintenance to ensure that they remain in peak operating condition. Cleaning them on a regular basis is one approach to maintain them in good shape. If you’re interested in learning more about how professional plumbers clean grease traps, here’s a step-by-step tutorial to help you out. 1.

How Restaurant Grease Traps Work – Miller Septic Services

A grease trap at a restaurant is a device that is meant to prevent fats, oils, and greases (FOG) from entering the sanitary sewage system. They are particularly significant in restaurants where the wastewater has a high concentration of FOG. Grease traps also prevent other particles from obstructing drains, such as sugar, cream, and other solids, from clogging the drain.

Why Do We Need to Keep Fat, Oil, and Grease Out of the Sewer System?

When grease-laden wastewater makes its way into sewage pipes, it may solidify and cause obstructions, as well as damage the pipes themselves. As a result, the majority of local governments require the usage of grease traps in commercial establishments. If you have a restaurant kitchen, every time you run the sink or the dishwasher, the contaminated water drains to the grease trap through a pipe.

Components of a Grease Trap

A grease trap is composed of five components: Water enters the grease trap through the inlet pipe, which allows it to reach the grease trap. 2. Flow rate controller – This device reduces the speed at which wastewater flows before it reaches the grease trap. 3. Baffles – metal obstacles that delay the flow of wastewater, allowing it to be separated from fat, oil, and grease more effectively. Fourth, water cools the wastewater, which allows the grease to solidify and separate from the wastewater.

Outlet pipe – this is the conduit via which wastewater is discharged to the sewage system.

Avoiding Restaurant Grease Trap Clogs

Making sure your grease trap doesn’t get blocked is an important part of maintaining its effectiveness. Clogs usually occur as a result of grease building up in your trap over time, stopping water from flowing through it. It is also possible to have a clog form in the input pipe, which will prevent water from entering the grease trap. If this has occurred, you may observe water backing up in sinks or floor drains as a result. Another location where a clog might form is in the outlet pipe, which prevents wastewater from exiting the grease trap completely.

In addition to preventing needless food waste from entering your drains, you should keep your grease traps in good working order by arranging regular cleanings.

Why Should You Have Grease Trap Installation

Drains being clogged are a typical occurrence in both homes and businesses. Even more ubiquitous in kitchens are grease, fats, and oils. (See also: Unfortunately, the two are highly connected with one another. While grease, fats, and oils are excellent for preparing delectable meals, disposing of them may be difficult. Putting them in the sink is the quickest and most convenient solution, but it comes with a number of concerns. Our experience at Septic Connection has shown us that grease may cause a variety of complications with plumbing systems.

There are several advantages to having a grease trap installed, which will be discussed in this article.

The Danger of Fats, Oils, and Greases

Pouring fats, oils, and greases (FOG) down the drain can result in a plethora of unpleasant and expensive consequences. They have the ability to block drains in your plumbing system, just as they have the ability to clog arteries in our bodies. Using a little quantity of FOG, you may appropriately dispose of it by pouring it into an empty jar or container and putting it in the garbage. Businesses, whether they are located in residential or commercial premises, must dispose of a significant amount of FOG.

The grease trap is used in large-scale facilities such as restaurants and cafeterias to collect grease.

What Is A Grease Trap?

Designed to collect and store FOG so that it does not enter the plumbing system and create difficulties, a grease trap collects and stores FOG in a container. These appliances are available in a range of sizes and are not the most aesthetically pleasing components of a kitchen. As a result, they are frequently put in obscure locations such as behind sinks or outside. From the exterior, they appear to be nothing more than plain metallic canisters. There are compartments filled with water as well as pipelines flowing into and out of the grease trap included within these containers.

How Does A Grease Trap Work?

Designed to catch and store FOG so that it does not enter the plumbing system and create difficulties, a grease trap is a device that collects and stores grease. Despite the fact that these appliances are not the most aesthetically pleasing aspect of a kitchen, they are functional and necessary. So they are commonly hidden in obscure locations such as beneath sinks or outside. They appear to be plain metallic canisters from the outside. There are water-filled compartments as well as pipelines flowing into and out of the grease trap included within these containers.

The Special Benefits of Grease Traps

As previously stated, grease traps aid in the prevention of clogging by “catching” FOG and chilling it to the point where it floats to the top of the grease trap, preventing blockage. The advantage, on the other hand, is not restricted to your own possessions. Grease traps benefit both the environment and the public by preventing foul-smelling gas (FOG) from entering the sewage system, rivers, and streams. These FOG would pollute water, potentially rendering it unfit for human consumption and posing a threat to animals that live in these areas.

Septic Tanks and Grease Traps

Grease traps have been used in restaurants and food processing companies for many years to keep fats, oils, and grease (FOG) from entering the septic tank and ultimately the drainfield or sewage system. These devices, when properly serviced and maintained, are extremely successful at lowering the level of FOG in the system. Is it possible for them to be used in home septic systems? If permitted to enter the system unchecked, FOG may cause significant damage to septic systems. In addition to generating obstructions on the walls of pipelines and tanks, it can disturb bacterial life, depriving the septic tank of one of its most important tasks.

  • There are patents in the United States that date back to at least 1884.
  • The majority of grease traps are designed in such a way that incoming wastewater is allowed to enter in a “clean zone” within the grease trap.
  • During the trapping process, wastewater leaves via a baffle with an aperture located at the bottom of the trap.
  • The suspension of FOG in grease traps will not remain in the trap if they are not maintained or pumped on a regular basis and are allowed to fill up with FOG.
  • In situations like this, the trap is completely ineffective.
  • The use of grease traps is required for restaurants and food processing facilities in the majority of parts in the nation.
  • The levels of FOG are raised in businesses such as those mentioned above.
  • What about grease traps for home sewage systems, if grease traps are essential for commercial operations but not for domestic septic systems?
  • They should be installed ahead of the kitchen sink(s) and in front of the septic tank.
  • This is also a condition that is unlikely to alter in the near future.
  • Installation costs would also be greater since there would be more assets to acquire and install, which would drive up the overall cost.

So, despite the fact that it appears to be a smart idea, grease traps will very certainly always be considered a business rather than a residential septic system component.

Is It Time to Install a Residential Grease Trap?

If you’re acquainted with the term “grease trap,” it’s most likely because you work in the business sector. In addition to being commonly associated with restaurants and other enterprises, grease traps may also be quite useful in the home setting. Not only is a grease trap more beneficial if you have a septic system, but it may also be more beneficial to the environment in general.

What is a Grease Trap?

A grease trap, also known as an interceptor, is a tank that collects and filters kitchen wastewater before it is discharged into the septic system. FOG interceptors and separators are designed to intercept and remove FOG (fat, oils, and grease) from wastewater before they reach your septic system, as the name implies. If FOG continues to enter your septic system on a regular basis, you might be in for a serious backup. The question is, where does a household grease trap reside. The most convenient placement would be beneath your sink, but if you have many sinks that are used for cooking, it might alternatively be located outside the house.

Why Invest in a Grease Trap:

  • If you cook on a regular basis, a grease trap may be required. Grease traps are non-toxic and ecologically safe. To keep your pipes from suffering unnecessarily wear and tear

You Cook Often

If you are the type of person who cooks in the kitchen seven nights a week, a grease trap will save you from having to call us for a clog or blockage, and it may even be a kitchen plumbing need for your home. Despite the fact that you may be vigilant in preserving your pipes against fats and oils, a buildup of these substances might occur over time. By installing a grease trap, you can ensure that your plumbing and sewers are completely clear of FOG! You’ll have more time to cook and less time to worry about what’s going down your drains and what isn’t going down your drain.

Environmentally and Economically Friendly

Rather of having your fats, grease, and oils go into your sewer system, they are intercepted, which helps to prevent contaminants from entering your water supply. Apart from preventing water pollution, you may also utilize your grease interceptor to recycle gray water, which you can then use to irrigate your grass or garden. You’ll save money on water waste! It is possible that by preventing clogged pipes, you will also avoid the need to repair them, which will save you a lot of money over time.

When and Why to get Maintenance

It is advised that you flush any food or grease down the drain with hot water once it has been flushed down the drain. The length of time between cleanings and the longevity of your grease trap will be increased as a result of this practice. Slow drainage, a blockage, or a strong and unappealing stench are the most obvious signals that it’s time to clean your drains and pipes. When it comes time to pump your grease trap, it’s important to be aware of the restrictions in your wastewater district.

When it comes time to clean, you’ll want to make sure it’s done efficiently and effectively by a professional, since it might pose a fire hazard if not done correctly.

It is possible that a hydrojetting will be required. For home grease trap services in San Diego or the surrounding regions, call us immediately at (866) 374-0402 to set up an appointment.

When disposing of food or grease down the drain, it is advised that you flush the drain with hot water to remove any remaining particles. The length of time between cleanings and the longevity of your grease trap will be increased as a result of this procedure. It’s time to clean your drains if you’re experiencing slow drainage, a clog, or a strong and unpleasant stench. Knowing your wastewater district’s laws when it comes to pumping your grease trap can help you when the time comes. Cleanings may only be performed on an as-needed basis in some cases, but not always.

Hydrojetting may be required on a number of occasions.

Great information on Grease Traps!

Often referred to as a grease trap or grease interceptor, a grease trap or grease interceptor is a receptacle that is located between the restaurant drain lines and the sanitary sewer lines. It is responsible for the separation and collection of fats, oils, and greases (FOG) from used water, thereby preventing such materials from entering the municipal sewer system. The grease trap can be installed either inside or outside of the institution, depending on the circumstances. In most cases, major restaurants or school kitchens would have their grease trap/grease interceptor installed outside of the institution, generally in the ground, but smaller facilities can usually accommodate their traps inside the facility.

Why do I have to have a grease trap?

FOG causes all kinds of problems for municipal wastewater systems, which is why local governments require commercial kitchens to have a grease trap installed in order to prevent this. FOG levels in water exiting an enterprise will be regulated by most municipalities to a minimum permissible level. If these bare minimums are not met, penalties may be levied.

How do grease traps work?

Grease traps are designed to delay the flow of water flowing from drains, giving the water and grease time to cool before it is discharged. Grease coagulates and rises to the top of the trap as a result of this chilling process. Other, heavier particles sink to its bottom due to the cooling process. The remainder of the water is free to flow through and into the city sewer system.

How do I maintain my grease trap?

Proper grease trap maintenance is critical in order to ensure that the grease trap is running as effectively as possible. If the amounts of accumulated FOG and solids are not closely monitored, a variety of issues might arise. Drain line obstructions and backups, unpleasant odors, and even worse, an excessive amount of FOG being deposited into the city sewer systems, which may result in large penalties, are all possible problems. Cleaning the grease trap may be accomplished in a variety of methods depending on its size.

  1. Nevertheless, in addition to any statutory pump-outs that may be required, there are alternative techniques of cleaning a grease trap that should be taken into consideration.
  2. This might normally include physically shoveling and vacuuming away the collected FOG and sediments, which would then be disposed of with the regular solid waste stream.
  3. When the FOG collection in the grease trap becomes excessive, most restaurants with bigger grease traps would often hire the services of a professional recycler/hauler to pump-out and maintain the grease trap.
  4. The use of a bacteria additive in the grease trap is one grease trap maintenance routine that any restaurant or kitchen may apply to manage the buildup of FOG and reduce the need for pump-outs, among other benefits.
  5. This can considerably minimize the need for regular pump-outs, as well as the scents released by the grease trap, which can be controlled.
  6. Grease trap bacteria is available in a number of different varieties.
  7. In addition to bacteria blocks, which are slow-dissolving blocks that are hanging from a rope and buried in the grease trap, another popular design is aeration blocks.

Powder variants are also available, and they often take up less shelf space and are less expensive to ship than liquid types.

Along with reducing FOG in the trap, bacteria can also be beneficial to drain lines in the kitchen by reducing the buildup of grease in the pipes.

Other important considerations for proper grease trap maintenance include making sure and keeping records of when maintenance operations, such as pump outs, clean outs, and when bacteria is added, are performed and when they are not.

Encourage your employees to dispose of solids and other garbage in the trash whenever feasible.

This entails flushing the lines with hot water to remove any oil or other buildup that has accumulated.

Finally, be wary of items that contain solely enzymes.

As a result of the ultimate coagulation and solidification of this grease in the wastewater treatment system, it just leads to additional problems down the line. As a result, numerous towns have passed ordinances forbidding the use of such items.

Grease trap – Wikipedia

A grease trap (also known as a grease interceptor, grease recovery device, grease capsule, and grease converter) is a plumbing device (a type of trap) that is designed to intercept most greases and solids before they enter a wastewater disposal system. It is also known as a grease interceptor. Small amounts of oil are present in most wastewater, and these oils accumulate in septic tanks and treatment facilities, forming a floating scum layer. Microorganisms in the anaerobic digestion process take a very long time to digest and break down the thick scum layer that forms on the surface of the water.

  1. After being allowed to cool, high-viscosity fats and cooking greases such as lard solidify, and when they combine with other disposed solids, they can clog drain pipes.
  2. The fats, oils, greases, and solids (FOGS) traps help to minimize the quantity of FOGS that enters sewers.
  3. They only have one purpose: to drain kitchen waste water.
  4. They may be manufactured from a variety of materials, including stainless steel, polymers, concrete, and cast iron, among others.
  5. They can be found above ground, below ground, inside the kitchen, or on the exterior of a building, among other places.

Grease trap manhole covers outside a restaurant are shown here. Generally speaking, there are three different sorts of gadgets. Many manufacturers specify ASME (American Society Of Mechanical Engineers) specifications, which include baffles or a patented input diffuser. These are the most popular. The size of the grease trap is determined by the size of the 2- or 3-compartment sink, dishwasher, pot sinks, and mop basins in the kitchen. Many manufacturers and distributors use online sizing tools to make these computations as simple as possible for their customers.

  1. Consideration is given to both the cumulative flow rates of these devices and their total grease retention capacity (measured in pounds or kilograms).
  2. According to this regulation, grease interceptors must eliminate a minimum of 90 percent of entering FOGs before they may be used.
  3. This third-party testing must be performed by a testing laboratory that has been recognized and approved by the FDA.
  4. Passive grease interceptors are large in-ground tanks that hold 500–2,000 US gallons (2,000–8,000 L) of water and serve as passive grease interceptors.
  5. Gravity interceptors are a term that is widely used to describe them.
  6. As more wastewater is introduced into the tank, the grease-free water is forced out of the tank by the increasing volume of wastewater.
  7. The brown grease is not recycled and is instead disposed of in landfills.

When passive grease traps and passive grease interceptors reach 25 percent capacity, they must be emptied and cleaned out.

A grease trap that is completely filled will not prevent any FOG from entering the sanitary sewage system.

Hydromechanical Grease Interceptors (HGIs) are a third type of device that has grown increasingly popular in recent years as eateries operate in more unconventional locations than ever before.

When measured in terms of grease capacity, HGIs take up less space and contain more grease as a percentage of their liquid capacity — frequently between 70 and 85 percent of their liquid capacity, or even greater in the case of some Trapzilla models — than other types of grease traps.

Most are constructed of sturdy plastic or fiberglass, which allows them to survive far longer than concrete gravity grease interceptors do.

The majority of manufacturers go above and above the minimal criteria to display the unit’s full capability.

Even if their tanks just passively intercept grease, they are equipped with an automated, motorized device for extracting it from the tank and depositing it in a separate container.

It is common for them to be put in an inconspicuous manner in your commercial kitchen, such as in a corner or below a kitchen sink.

You will not be required to pay monthly pumping fees, which will result in a reduction in your overall business running costs over time.

Furthermore, the tiny form of these units allows them to be installed in confined spaces and is simple enough to be completed as a short do-it-yourself job. It’s as simple as connecting the pipes and plugging them in.


Outside of a shop, there is an in-ground grease trap. The waste grease produced by restaurant and food service kitchens, which is present in the drain lines from various sinks, dishwashers, and cooking equipment, such as combi ovens and commercial woks, is a health hazard. A significant amount of waste grease has also emerged from rotisserie ovens. If the grease is not cleaned, it can clump together and produce a clog and backup in the sewer. Every year in the United States, sewers back up an estimated 400,000 times, with municipal sewage overflows occurring on 40,000 instances.

Even if accumulated FOG does not result in blockages or sanitary sewer overflows, it can cause disruptions in wastewater utility operations as well as an increase in the amount of time spent on operations and maintenance.

In areas where FOG is a hazard in the local wastewater system, towns have created inspection programs to verify that grease traps and/or interceptors are properly maintained on a regular basis.

Method of operation

During the outflow from the kitchen sink and into the grease trap, the solid food particles sink to the bottom of the trap, while lighter grease and oils float to the top of the trap. Once the water has been cleaned of grease, it is pumped into the regular septic system for disposal. Food particles at the bottom of the tank, as well as floating oil and grease, must be removed on a regular basis in a manner similar to septic tank pumping. A typical grease trap is not a food disposal item in the classic sense.

  • Poured beverages, gravy, sauces, and any other food solids must be scraped off of plates before they are placed in the sink or dishwasher.
  • Unfortunately, having a big tank for the effluent to stand in also means that food waste has more time to sink to the bottom of the tank, limiting the available volume and increasing the difficulty of cleaning out the tank.
  • In the case of mild steel or concrete, this results in the formation of “rot out.” Acid-resistant qualities are provided by polyethylene, on the other hand.
  • In most circumstances, numerous interceptors connected in series will perform significantly better at separating grease.

Because it has been sitting in the trap for an extended period of time, the grease that has been collected will be tainted and unfit for further use. Brown grease is the name given to this sort of grease.

Brown grease

This articleis missing informationabout yellow/brown classification by free fatty acid content;trap grease.Please expand the article to include this information. Further details may exist on thetalk page.(December 2021)

Brown grease is the term used to describe the waste produced by passive grease traps and gravity interceptors. In conjunction with fats, oils, and grease, brown grease is made up of rotting food solids (FOG). Grease pumping vehicles remove brown grease from traps and interceptors and pump it into a storage tank. In contrast to the collected yellow grease, the vast majority of brown grease is disposed of in landfills. Brown grease is being recycled for the first time thanks to new facilities (2012) and cutting-edge technology.

Grease Trap vs. Grease Interceptor

It was 1880 when grease traps were first introduced and the technique has remained virtually unaltered since then. When it comes to grease traps and grease interceptors, the technology is the same regardless of the kind of device. Because the wastewater contains fats, oils, and grease (FOG), it floats to the surface and flows into the sewage system. In accordance with the Universal Plumbing Code, “a grease trap/grease interceptor is a plumbing device that is put in the sanitary drainage system to ‘trap’ or ‘intercept’ non-petroleum fat, oil, and grease (FOG) from a wastewater discharge.” In a tank, wastewater is collected after it has been collected in a sink or drain.

  • FOG fills the grease trap from the top down, displacing wastewater from the centre of the grease trap and directing it into the sanitary sewage system or septic tank.
  • When the flow rate is less than 50 gallons per minute, a grease trap performs admirably.
  • Top restaurant chains entrust us with the control of their grease and oil.
  • Liquid Environmental Solutions is also trusted to service the grease traps and grease interceptors of thousands of regional, independent, and single-location businesses.

Your septic system is in charge of eliminating wastewater from your property and safeguarding you and your family from germs and other harmful substances. This device keeps grease and fats produced by industrial cooking out of the sewage system, where they may otherwise block and damage pipes.

How a Septic System Works

Unified drainage systems (UDS) are a type of wastewater treatment system that is installed underground and used to disinfect water that comes from the residential plumbing system. Typically, this sort of system is employed in rural locations where there are no municipal sewer systems. A septic tank, as well as a drain field or soil absorption field, are used to treat wastewater in a residential septic system. It successfully removes all waste from the water by utilizing a combination of natural processes and established technologies.

  • In this system, wastewater is discharged from the home through a single main drainage pipe and collected in an underground septic tank, which keeps waste away from the surface by isolating it inside. In order for the wastewater to be properly treated, it must be held in the tank until the sediments settle to the bottom and oil and grease float to the top. The liquid wastewater travels from the tank to the drain field after the particles and oil have separated. The pretreated wastewater is channeled onto the drain field where it filters through the soil to remove any remaining contaminants. As water passes through the drain field, it is naturally accepted, treated, and dispersed by the soil
  • Wastewater percolates into the soil, where it is naturally cleansed of dangerous coliform bacteria and other toxins by the soil’s natural processes. The purified water finally finds its way into the groundwater system.

Grease Traps

Grease traps are available from Advanced Septic Services. 2018-01-19T 18:09:36+00:00 Your septic system is responsible for decomposition of waste, not grease. With the ease with which oils and fats now make their way into septic tanks and wastewater treatment systems, they can block pipes and drainfields. Grease traps, on the other hand, can halt this process in its tracks. First, let’s take a look at why grease is detrimental to waste disposal systems and how grease traps may be used to mitigate this problem.

Why is Grease Bad for Septic Tanks?

Upon arrival at your septic tank after traveling from your residence, all of your waste is divided into three layers in your septic tank:

  • Bottom Layer: “sludge,” which is sewage waste that has not been broken down
  • Wastewater and partially digested particles from the sludge layer comprise the middle layer. Top Layer: the “scum” layer, which contains substances such as grease and fats that are lighter in weight than water

In addition to having the exit pipe in the intermediate layer, septic systems also have an exit valve, which allows wastewater and broken down particles to be pushed into the drainfield via. When the scum layer grows too thick, it pushes the middle layer to the bottom of the stack. When your septic tank begins to release grease and oil into the drainfield over treated wastewater, the pipes and field get clogged, reducing the ability of your septic system to properly handle waste. And it’s not just septic tanks that are at risk.

It clogs the pipes of sewer systems and creates obstructions in municipal wastewater treatment facilities, among other things.

How Do Grease Traps Work?

Grease traps are called properly because they catch grease before it enters the pipes that go to the sewer system or septic tank, as is the case with grease traps in general. Their natural waste division system consists of two baffle chambers that naturally partition waste into three levels. Initial separation takes place in the first chamber, which is connected to the second baffle by a conduit that runs from the middle wastewater layer. In the second baffle, there is an exit pipe that permits waste water (without the grease) to be discharged to the sewer or to enter the septic tank.

As the traps fill up, the quantity of money grows.

It will eventually become clogged and cease to function.

Do Residential Septic Systems Need a Grease Trap?

While grease traps are required for commercial systems, particularly in the food service and hospitality industries, they are not required for residential septic systems. The most critical piece of advice for residential properties is to adhere to strict “Do Not Flush” regulations.

Using the trash can instead of the garbage disposal and cleaning dishes and pans before placing them in the dishwasher will help you avoid introducing oil into your system. Installing effluent filters will also assist to limit the quantity of oils and fats that enter your drainfield in the future.

Grease Trap Service

After being clogged, your grease trap will emit a foul odor and may become potentially hazardous due to various safety issues linked with improperly maintained traps. This is when Advanced Septic Services comes in. Unlike some surgeries, our professional experts do not just scrape away the top layer of the skin, leaving hardened deposits behind. We clean the whole trap, including any unbroken down waste, scum, and hardened grease that has accumulated over time. Once your grease trap has been professionally cleaned, it will be clear of any accumulations or unwanted aromas.

Grease traps can save your business waste disposal system, whether it is a sewer or a septic system.

However, grease traps, like the rest of your system, require regular maintenance.

Septic Science: The Anatomy of a Grease Trap

Home»Septic Science: The Anatomy of a Grease Trap»What is a Grease Trap? Grease traps, while not present in every septic system, can play an important part in the operation and maintenance of your septic system if they are installed and maintained appropriately. Septic tanks with grease traps are designed to restrict the entrance of Fats, Oils, and Grease (FOG) into the tank and allow these materials to cool as fluids progress through the system and disperse without clogging the pipes. Despite the fact that grease traps are not sophisticated devices, their design, particularly when used in conjunction with a septic system, is ingenious and makes use of certain fundamental physics and biology to separate items and keep the entire system running smoothly.

For all others, see How Do Grease Traps Work?

Let’s get started!

What are grease traps and why are they important?

First and foremost, let us discuss definitions. Grease traps serve as a link between the plumbing pipes in your house or restaurant and the rest of the septic system, collecting grease and other waste. In order to separate greywater (also known as effluent) from floating FOG and sinking silt, they employ strategically located pipelines and tanks. As a result of FOG and sediment buildup in septic drain pipes, sewage backup can occur, and septic systems may fail to perform as intended.

How do underground grease traps work?

Using two subterranean tanks – a primary tank and a secondary tank – grease traps are used to transport greywater (effluent) and wastewater while excluding fats, oils, and grease from the mixture. The primary tank is the container into which sewage from your house or restaurant is discharged. The various elements naturally separate from one another in this basic tank. Heavier debris, such as meals, sinks to the bottom of the tank, while fats and oils float to the surface. The effluent is left in the middle of the process.

Using a crossover pipe, the primary tank is linked to the secondary tank.

A flow diverter may also be included in the primary tank, which acts as a barrier to prevent soils and oils from being pushed into the crossover pipe as a result of momentum.

The two tanks will then continue to fill equally until they reach the exit pipe, where the effluent may be discharged into the septic system.

A little inclination in the outlet pipe will allow the secondary tank to fill past the mouth of the pipe, guaranteeing that whatever fats, oils, and grease did manage to make it into the secondary tank will float above the outlet pipe instead of being drawn through it.

Caring for your grease trap

While the primary function of your grease trap is to prevent fats, oils, and grease from blocking your entire septic system, its secondary function is to break down sediments so that the septic system may continue to function properly. It accomplishes this through the use of naturally existing bacteria, making it critical to maintain the right environment in your grease trap. Pouring dangerous chemicals down your drains will kill microorganisms and inhibit the dissolving of fats, oils, and grease in your grease tap, so be careful not to do so.

Above all, remember to get your grease trap serviced on a regular basis as part of your septic system’s routine maintenance.

Grease Traps & FOG Management

Grease traps or grease interceptors are used by foodservice establishments and restaurants to manage wastewater as well as fats, oils, and grease emitted during food preparation (FOG). Due to the fact that fats, oils, and grease (FOG) are the most common cause of sewage backups and overflows, it is critical to understand how FOG develops and how to properly control it. Jones PlumbingSeptic Tank Service is a competent and qualified grease trap pumping and maintenance service provider in the greater Philadelphia area.

Now is the time to request service.

FOG Explained

Food preparation and cooking produce a lot of fats, oils, and grease (FOG), which are frequent byproducts. When opposed to a residential kitchen, FOG develops on a bigger scale in commercial kitchens, such as restaurants, because to the higher cooking volume. Therefore, the usage of a grease trap or interceptor, as well as frequent maintenance of it, are essential components of FOG control. Following best practices, such as the ones listed below, will aid the plumbing between maintenance visits:

  • Never pour frying grease and/or grill drippings down the sink or into the toilet. Grease spills should be cleaned up using paper towels, and the old towels should be disposed of in the garbage. Make sure to empty oil and food particles into the trash before you wash your dishes or pots and pans.

Don’t Pour FOG Down The Drain

The most common argument for not flushing FOG down the toilet is the blockages that will build as a result of doing so. It is not a question of if, but rather when. When fats, oils, and grease are dumped down a drain, they may appear to be liquids at first, but they will congeal and solidify as the water cools. As a result, buildup occurs fast, and the oils, fats, and grease cover everything in the pipe as they move through it.

Following the development of a clog, wastewater begins to back up in the pipe and creates an unpleasant mess to clear. Jones PlumbingSeptic Tank Service can provide skilled grease trap cleaning services if you fear FOG has collected inside your business’s plumbing.

Difference Between Grease TrapGrease Interceptor

A grease trap is used by some firms to collect grease, but others rely on a grease interceptor to collect grease. So, what exactly is the distinction? Neither has a different flow rate for wastewater, but they both provide the same job in terms of preventing FOG from entering piping. Grease traps are used for flow rates of less than 50 gallons per minute, whereas grease interceptors are utilized for flow rates more than 50 gallons per minute (see diagram). Jones PlumbingSeptic Tank Service conducts routine grease interceptor and grease trap servicing for commercial customers.

Issues Created By FOG

An accumulation of FOG, in addition to producing the issues outlined below, frequently produces an unpleasant odor. Jones PlumbingSeptic Tank Service periodically pumps grease traps, which helps to avoid smells and other sorts of problems that might arise as a result of grease build-up.

Clogged Pumps

If the FOG does not block the drains and piping that are attached to the business’s grease trap, it will go on and clog the pumps at lift stations and wastewater treatment plants. Because lift stations and treatment facilities service a large number of companies, a clogged pump can cause problems for those who rely on them.

Malfunctioning Floats

It is the job of the pumps in a lift station to tell when to switch on and begin transporting wastewater from the business’s plumbing to the main sewage line. However, if a float becomes engulfed in fog, it is unable to communicate with the pump about when to start functioning. Due to the fact that FOG continues to accumulate and wastewater backs up rather than flowing out, this can cause damage to the pump and the entire plumbing system.

Dangerous Gas Formation

Bacteria that feed on FOG produce hydrogen sulfide, a toxic gas that can become trapped in enclosed places such as underground sewer systems and other similar structures. The odor of this gas is comparable to that of a rotten egg. When combined with water, it has the potential to corrode metal and concrete over time, resulting in a breakdown of infrastructure.

City-Wide IssuesRepairs

FOG is an issue for more than just your company’s operations. Another major source of contamination is the dumping of fryer grease and grill drippings into grease traps and grease trap disposals. In a restaurant, a typical week might generate hundreds of gallons of FOG, if not thousands of gallons. Even with a grease trap or interceptor in place, if grease is dumped down a drain, the plumbing and treatment plant at the other end of the line will get overwhelmed. Pumps and other components of the treatment plant become blocked as a result of the buildup of FOG.

Many towns and municipalities have ordinances prohibiting the disposal of fryer grease and grill drippings in a grease trap or sewage system. Businesses who engage in this practice, if discovered, incur substantial fines as well as a tarnished public image.
