A grease trap (also commonly known as gas recovery device, grease capsule, grease interceptor, and grease converter) is a type of plumbing device which is used to block or intercept maximum amount of solids and greases before they enter into a wastewater disposal system. Wastewater from the plumbing system contains a small number of oils and solid which gets into the septic tanks and during the treatment process it produces a floating scum layer. It takes a lot of time for the scum layer to get properly digested and broken down by the microorganisms in the anaerobic digestion process. Large amounts of oils present in food thrown out by the restaurants can drown the treatment facility or treatment facility, which ultimately results in the release of untreated sewage into the environment. Grease traps can be maintained by using the denver drain cleaning company, drainage camera inspection and plumbing denver.

Even from the Victorian days people are usin the grease traps. Nathaniel Whiting patented the first grease trap in the late 1800s. The grease traps are available of different materials, such as plastics, concrete and cast iron, stainless steel. The grease traps have a range of capacity varying from 35 litres to 45,000 litres or even greater. Grease traps can be located at different locations such as below the ground, above the ground, outside or inside the kitchen.

Restaurants, hotels, and foodservice kitchens generates waste grease in a huge amount which is present in drain lines transported from various dishwashers, sinks, and cooking equipment such as commercial works and The traps block the entry of fats, oils, solids and greases from entering into the sewers or septic tanks. combi ovens. If this grease waste is not removed properly, then it can cause blockage in drainage and sewer system. In the US only, Sewers back up, estimated at 400,000 times a year and the municipal sewers overflow over on 40,000 occasions.

The EPA has determined that the main reason for sewer flows is the blockages in the sewer pipes and the primary reason for blockages in the sewer is the grease. Even if the collected FOG does not cause blockages and sanitary sewer overflows, it can interrupt wastewater usage operations and increase the maintenance and operations required.

According to a recent report, more than half of all the sewer overflows happens because of grease blockages, with more than 10 billion US gallons (38,000,000 m3)or raw wastewater spills annually.
