What are grease trap interceptors? Grease interceptors or basically the same as a Grease trap. They are devices that are designed to intercept fats oils and greases before the leave the kitchen or processing center and allowed to flow out into the waste water treatment facility or city sewer and water treatment plant. Waste water produced by restaurants and food processing centers are typically contaminated with fats, oils and grease (FOG). The untreated contaminated waste water must flow through a grease interceptor treating by removing the grease before it can be discharged into the city sewer system or the onsite waste water treatment plant. If the fats, oils and greases (FOG) are allowed to escape into the waste water treatment facilities or city sewers treatment facilities clogging systems the cost of repairs and down time can increase operating expenses dramatically for the facility.
Municipalities are adopting new rules and regulations regarding the oversight of facilities producing fats, oils and greases enforcing corrective procedures and proper disposal of fats, oils and greases (FOG) before leaving the facilities contaminating city sewer lines, onsite treatment system or septic tank and drain fields.
When fats, oils and greases (FOG) contaminate downstream systems, the grease become further contaminated with pathogens, chemical and various types of metals rendering the grease unsuitable for recycling. Fats, oils and grease will eventually coagulate downstream causing system to fail. Municipalities are spending millions on replacing large sewer pipes and systems.
There are several different designs of grease interceptor systems available on the today’s market. Generally speaking, two types are most commonly used. Some systems are automatic also known as AGRU or (Automatic Grease Removal Units) this type of system remove grease automatically when trapped in the unit, a float switch is activated by the rising level of water or effluent. MGT or (Manual Grease Trap) is typically less expensive to operate and most often found in smaller restaurant facilities due to the cost of the unit. A well maintained MGT system will remove almost 100% of fats, oils and grease from the effluent, allowing waste water to flow into the waste water treatment plant for further processing.
When purchasing a grease interceptor, it is important to make the grease interceptor salesman aware of the gallons per day (GPD) being used daily. This will be the determining factor in the size of tank required for your facility.
Remember, a properly installed grease interceptors is key to the successful operation of a restaurant. A smooth operating grease interceptor will ensure odor control and containment of fats, oils and greases (FOG) ensuring safe operation and compliance with any and all municipality rules and regulations.
