Fat, Oil and Grease (FOG) Generation
The greatest drainage problems faced in kitchens and food preparation areas is the collection of fat, oils and grease (FOG) within the drainage system. These substances form naturally from animal and vegetable foodstuffs that can expensive burden in sewer pipes, leading to blockage and reduced capacity, causing the need for frequent blockage clearing. Sometimes, sewer pipe must be replaced due to solidification of the grease and other debris.
Why Are Grease Interceptors Needed?
1.To prevent drainage System in buildings from becoming clogged.
2.To prevent sewer lines from clogging and improve operation of sewerage treatment plants.
3.To prevent enviromental problem caused by FOG with other debris at landfills and in Waterways.
4.To promote the recycling of recovered clean grease. Recovered grease can be used in manufacturing of fertilizers, soaps, animal feed, cosmetics, and components of explosive such as nitroglycerine.
BESTEC Biological Grease Interceptor is compact, efficient unit that operate by separating FOG from the drainage water by reducing the velocity and henca the momentum of the incoming liquid into the Interceptor. Any heavier solids in the liquid settle into a removable perforated bucket as the turbulence of the incoming fluid reduces and the FOG globules being less dense than water, float above the water.
The separated water is then forced under a stainless steel baffle plate arrangement to ensure any grease, oil or fat residues are not discharged into the maiin drainage system from the grease interceptor.
When selecting a biological grease interceptor, careful consideration
should be given to the following factors:
– Location of the grease interceptor sited inside or outside the building
– In-ground or free standing application
– Traffic / wheel loads for in-ground applications
– Connecting drainage invert levels for in-ground applications
– Correct hydraulicsize of grease interceptor for the application
