Grease Trap

Grease traps (also known as grease interceptors, grease recovery devices and grease converters) are plumbing devices designed to intercept most greases and solids before they enter a wastewater disposal system.

Common wastewater contains small amounts of oils 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 upstream production can overwhelm the septic tank or treatment facility, causing a release of untreated sewage into the environment. Also, high viscosity fats, grease and oil, and can combine with other disposed solids to form blockages in drain pipes.
