Grease trap or grease interceptors are not only beneficial for our environment but are require by your local municipality.
A grease trap or grease interceptor is basically a plumbing device installed between the drains in a kitchen and the municipal sewer lines. The principle objective of a grease trap or grease interceptor is to separate and collect all FOG’s (fats, oils, grease) and solids (food residue) from the wastewater, preventing such materials from entering the sewer system.
There are several types of grease traps. The most common are; the In-Kitchen grease trap, this type is typically installed in most restaurants, adjacent to a dish-washing sink. In-Ground grease traps are typically installed in high cooking volume establishments, they are typically installed underground outside the facility.
Grease traps achieved their objective by slowing down the water flow from the drain lines, this action allows the FOG accumulated in the wastewater to coagulate to the top of the trap while the accumulated solids sink to the bottom. The remaining water (Grey Water) freely flows through the sewer lines to the municipal wastewater treatment plant.
In order to maintain the operating efficiency of the grease trap, prevent foul odors and drain line back-ups, the grease traps should inspected and cleaned on a regular basis. The frequency of this service is based on the size of the grease trap and cleaning procedures of the kitchen staff. Most municipalities recommend a monthly cleaning service to the grease trap or grease interceptor.
Pump-Out Method “is the most effective and recommended. An increasing number of municipalities have ordinances requiring this method to be utilized on a regular basis.”
Bacteria Additive Method “The applied bacteria, breaks down and digest the FOGs, what remains in the trap is carbon dioxide and water. Bacteria Additives can be introduce into the system in different forms, the most common is in liquid form, which can be manually pour into the drains and trap or by using an automatic injection pump which disperse the additive into the systems at set intervals. Another form is in powder blocks, which are placed inside the trap and slowly dilutes into the system.”
