Wastewater from sinks and dishwashers contains small amounts of FOGS (fats, oils and greases) which enter the drainage system which then flow into sewage treatment systems and septic tanks where they form a floating scum layer. This scum layer is very slowly digested and broken down by microorganisms in the anaerobic digestion process. However, excessive or large amounts of FOGS from food production in kitchens and restaurants can overwhelm the sewage treatment facility and septic tanks, 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, which can cause major problems with the drainage system and the environment.
The FOGI Grease interceptor/separator range has been designed to conform to BSEN 1825 the British Standard for Grease Separators. The FOGI design will effectively intercept (FOGS) fats, oils and greases and solids before they enter a wastewater drainage system in so supporting the effectiveness of both the drainage system and the final treatment process. FOGI interceptors/separators are designed for larger kitchens and restaurants as well as use in industrial food processing applications.
