Grease interceptors function using gravity and coalescence as a means of separation. Greases, fats and oils are about 89 or 90% of the weight of water. To separate them from water an interceptor provides a separation chamber which allows FOG to rise to the surface.
Temperatures in excess of 140oF will dissolve grease. Typical sink water temperatures will not dissolve grease which allows the grease to be trapped in the interceptor. Mechanical dishwashers operate at temperatures in excess of 160oF.
Many businesses use grease traps (also known as grease interceptors) as part of a waste management system to prevent sewer system blockages from accumulated waste fats, oils, and greases. Workers can be injured if they trip or fall into a grease trap that is not properly covered.
Grease Interceptor When fats, oils and grease (FOG) from preparing, cooking and processing different foods are discharged through dishwashing and other cleaning activities, the food service establishment (FSE) must effectively control those discharges to avoid clogging downstream sewer pipes. That is why applicable plumbing codes require a grease
Eventually, more grease becomes trapped and the buildup continues. These masses of FOG can grow dramatically based on the size of the pipe and lead to complete blockages, which can then lead to sanitary sewer overflows or SSOs. For precast concrete producers who manufacture gravity grease interceptors, the burning question is this: Is my tank
Almost all interceptors and grease traps fall into one of four categories: 1. Hydromechanical grease interceptors (HGIs) 2. Gravity grease interceptors (GGIs) 3. Automatic Grease Remove Devices (AGRD) 4. Chemical and biological systems Below we explain the differences between these four types. 1. Hydromechanical Grease Interceptors (HGIs)
Solidified grease can cause sewer blockages and overflows that pose unnecessary health hazards as raw sewage backs up into residence or commercial establishments. A properly plumbed and maintained grease interceptor will protect sewer systems from these occurrences.
Grease interceptors are installed on “gray” water drain lines and are designed to remove fats, oils and grease (FOG) from wastewater. The retained FOG should be regularly removed or pumped out of the interceptor.
