A grease interceptor or automatic grease removal device shall be required to receive the drainage from fixtures and equipment with grease-laden waste located in food preparation areas, such as in restaurants, hotel kitchens, hospitals, school kitchens, bars, factory cafeterias and clubs. As waste water flows through a kitchen's plumbing (3-compartment sinks, prep sinks, mop sinks, dishwashers, floor drains, etc.) Both HGIs and GRDs are vented on the outlet. The vent on the flow control is an air intake. Since the interceptor comes with a flow control in the inlet, if your drainage flow rate exceeds the rating of the interceptor the waste will back up and end up on the floor. . This is best done with an empty grease interceptor. %PDF-1.5 % For SI: 1 gallon per minute = 3.785 Protection Agency", or the authority in charge of the sewerage system into "F$H:R!zFQd?r9\A&GrQhE]a4zBgE#H *B=0HIpp0MxJ$D1D, VKYdE"EI2EBGt4MzNr!YK ?%_&#(0J:EAiQ(()WT6U@P+!~mDe!hh/']B/?a0nhF!X8kc&5S6lIa2cKMA!E#dV(kel }}Cq9 1014.3 Gravity Grease Interceptors Required gravity grease interceptors shall comply with the provisions of Section 1014.3.1 through Section 1014.3.7 . 986 0 obj <>/Filter/FlateDecode/ID[<632E8A8118BA4843ACCDCC779BF056AD>]/Index[978 15]/Info 977 0 R/Length 57/Prev 404255/Root 979 0 R/Size 993/Type/XRef/W[1 2 1]>>stream The purpose of a grease interceptor is to catch and collect fats, oils, grease, and solids (FOGS) from commercial and restaurant kitchens.

TRAP REQUIREMENTS. endstream endobj startxref Purchasing an interceptor prior to IW approval exposes the purchaser to risk of rejection and replacement costs. What's important to remember about AAVs is that they only allow for the relief of negative pressure in the drainage system. Some years ago, I was successful in getting a sizing table written in to Chapter 10 of the UPC relating fixture units to grease interceptor size, but the IPC still does not have such a table so it remains a mystery in that code. Extremely large volume GIs may have three compartments; While operating at the GI's rated flow capacity, the first compartment must provide a retention time of no less than seven minutes, and the second compartment must provide a retention time of no less than five minutes (~60/40 split); GI inverts and vents shall be external to the compartments. If you use this piece of equipment, I would get the vendor involved in the sizing. For grease trap or grease interceptor routine or emergency maintenance, please give us a call! Be aware that there is a maximum lift height of the vacuum pump on the service truck, so dont locate the unit more than one story below grade. Note that HGIs are generally located recessed into the floor or on the floor below if that is possible.

The UPC does not include provisions for AAVs except as a part of an "Engineered Vent System" under section 912.0, much to the chagrin of engineers around the country. The location of gravity grease interceptors is critical. H0FVy&K7FL+dR5e The Uniform Plumbing Code (UPC) does not permit a grease interceptor to serve as a fixture trap and also prohibits the installation of a vent between the air intake on the flow control and the grease interceptor. Hydromechanical grease interceptors shall meet the following requirements: Generally, HGIs are ideal for low FOG-producing establishments such as small sandwich shops, coffee shops, and bakeries that use disposable flatware and do not utilize an automatic dishwasher, due to the HGIs compact size. Section 890.510 - Grease Interceptor Requirements. Enzymes, solvents, and emulsifiers are not permitted as they will only change the form of grease, allowing it to be carried out of the grease trap with the wastewater and deposited in the collection system. HyTSwoc [5laQIBHADED2mtFOE.c}088GNg9w '0 Jb . Hunters Curve doesnt work because it is intended for water flow rates, not drainage. If you do provide a vent, how do you size it? To separate them from water an interceptor provides a separation chamber which allows FOG to rise to the surface. processes, meat packing and food processing facilities and similar processing This is a very handy feature indeed.
