A grease trap is used to prevent grease from entering the sewage system, which can cause clogs and disrupt wastewater treatment. It consists of a tank that separates solids and grease from water. Regular maintenance is required, and some establishments have contracts with rendering companies to dispose of the grease. Building codes may have specific requirements for grease control, and there are various manufacturers of grease traps. It is recommended to purchase a slightly larger grease trap than needed.
A grease trap is a plumbing accessory that people use to keep grease out of the sewage system. Normal household grease is not a significant problem, but in any environment where people work with a lot of greases, greases, oils and waxes, you need to protect your sewer with a grease trap. Municipal code often requires the use of such devices, and people need to make sure they are in good working order. In establishments such as restaurants, a public health inspector may ask to verify that employees clean it regularly.
If grease leaks into the sewer, it can cause a variety of problems. One is the hooves. Many types of grease and wax can solidify at low temperatures and form plugs in the line, forcing workers to clean out the plumbing line after it begins to clog. Grease can also disturb the balance of microorganisms in wastewater and can make treatment more difficult, as well as create a substantial mess in wastewater treatment plants.
The basic design of the grease interceptor consists of a large tank. Waste water flows into the tank and settles. The solids sink to the bottom, while the light fat floats to the top, leaving clear water in between. The water flows into a second tank and discharges to the sewer through a small pipe. Many also have baffles or screens to trap debris and large chunks of material as they flow into the primary tank.
Maintaining a grease trap requires periodically taking out and cleaning the screens, as well as removing solids and grease. These materials can go into a drum for disposal. Rendering plants can be used for blubber and in some cases it can also be used to produce biofuels, depending on the types of blubber present. Restaurants with large amounts of cooking oil usually have a contract with a rendering company to collect the barrels of grease on a regular basis.
People building a restaurant or other facility where grease will be present can check the building code for any specific requirements regarding grease control. Plumbers familiar with the code in a region can recommend specific products to meet the need based on the type of structure. A number of manufacturers produce grease traps along with replacement baffles and other parts for maintenance and repairs. Some things people might want to think about include ease of cleaning and manageability; It’s a good idea to purchase a slightly larger grease trap than you need, in case production increases.
