Grease traps (also known as grease interceptors, grease recovery devices and grease separators) are plumbing devices designed to intercept most greases and solids before they enter a wastewater disposal system. Common wastewater contains small amounts of fats, oils & grease (referred to as FOG) which enter into septic tanks and treatment facilities to form a floating scum layer. This scum layer is very slowly digested and broken down by microorganisms in the anaerobic digestion process. However, very large amounts of oil from food production in kitchens and restaurants can overwhelm the septic tank or treatment facility, causing a release of untreated sewage into the environment. Also, high viscosity fats and cooking greases such as lard solidify when cooled, and can combine with other disposed solids to form blockages in drain pipes.

 They work on the basic principal that FOG’s float on water and solid particles sink. Baffles within the trap slow the inflow of wastewater from the kitchen sinks. This allows for a settlement period where the separation of oils, water and food particles within the unit. A trap on the outlet prevents FOG’s from flowing directly through the unit with the FOG’s retained within the unit along with food particles allowing clean water to flow through. The retained waste will build up over time and requires regular servicing and removal of waste for environmental disposal.

The grease trap can be used in the following areas:
