How do you calculate grease interceptor capacity?
To size a Gravity Grease Interceptor with the flow determined in GPM you simply multiply the flow number by a detention time, 30 minutes (the time period normally excepted for the grease to separate by buoyancy). Again with our 20 GPM example, the size would be 20X30= 600. A 600 Gallon size interceptor would be used.
What is the difference between a grease trap and grease interceptor?
Grease traps are much smaller (typically about the size of bread box to a small mini-fridge), while grease interceptors are much larger. Capacity/flow. Grease traps handle flow rates of 10–50 gallons per minute, while grease interceptors accommodate flow rates of more than 50 gallons per minute.
How much does a 1500 gallon grease interceptor cost?
The average cost for the installation of a new grease trap (750 to 1500 gallons) is between $4000 and $8500.
What is the minimum capacity of a gravity grease interceptor?
500 gallons
Gravity Grease Interceptors (GGIs) are generally installed in the ground outside the facility, upstream from the “black” water (sanitary waste) drain line, and are at least 500 gallons in capacity.
What is the minimum size of a grease interceptor?
The gravity grease interceptor design incorporates two or more compartments in series, a minimum volume of 300 gallons and uses its larger volume of water to slow the flow velocity down, allowing the time required for the buoyancy of FOG in water to cause separation.
Do I need a grease trap or grease interceptor?
A grease trap works well with a lower volume of flow; less than 50 gallons per minute. Large-scale establishments with a higher volume of flow; more than 50 gallons per minute, will need a grease interceptor, as they are better equipped to handle the extensive FOG that flows through the device.
How much is it to clean a grease trap in a restaurant?
The cost of a professional grease trap cleaning varies and is based on the physical size of the grease trap. Typically, grease traps can be professionally cleaned for $115 to $1040.
How much does a 1500 gallon grease trap weigh?
Top to Center of Outlet 16″ Weight 2800 Lbs.
What is the difference between a hydro mechanical grease interceptor and a gravity grease interceptor?
Gravity-type units are identified by their holding volume in gallons. The other category of interceptors is known as hydro- mechanical. These units increase separation performance through the use of flow control, air intake and baffles, which markedly decreases the time necessary to separate.
How do you size an oil interceptor?
Oil Interceptors are sized according to the rate of incoming flow, in gallons per minute (GPM). For indoor applications, flow rate can be calculated by adding the maximum discharge rates of all poten- tial water sources. For example, a standard 3/4″ hose connection will discharge approx. 10 GPM.
