The drawing shows a PDI G101/ASME Type A grease interceptor connected to a the three compartment sink that is trapped and vented, an external flow control with air intake and a vent on the downstream side of the grease interceptor. Grease Interceptor. 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. I would size it as half the size of the inlet with a 2-inchminimum, but your AHJ might want you to use the connected fixture units so it is worth checking with your AHJ. It looks like your browser does not have JavaScript enabled. However, these requirements also allow larger HGI models if site conditions are not ideal for a Gravity Grease Interceptor. I would argue the former since, as noted above, each connected fixture is already trapped and the vent just serves to allow for the displacement of air it is not protecting a 1'' trap seal. %%EOF Los Angeles County grease interceptor detail. 691 0 obj <>stream Where to buy.

If it is a smaller indoor interceptor, some municipalities mandate servicing every 30 days. Manufacturer's want to provide guidance for a broad range of installations without providing detailed drawings for every single installation variable that can exist. 1014.3 Gravity Grease Interceptors Required gravity grease interceptors shall comply with the provisions of Section 1014.3.1 through Section 1014.3.7 . Venting is required on the downstream drain line - the same as most other plumbing appliances and fixtures to allow ecient and unrestricted discharge of the waste water . grease interceptor, correctly designed to separate light densitysubstances from wastewater, will not by itself govern or regulate theflow of water through the interceptor at all times to sufficiently assurethe "flotation" separation of the substances which are to be interceptedat maximum efficiency. 0 Copyright 2023 Greenway Waste Solution Site by Outliant | Privacy Policy, Top 3 Reasons for Grease Trap Maintenance, Greenway Waste Solutions Zooms Up with Griffin Brothers. Grease interceptor means an indoor device located in a food service facility or under a sink designed to collect, contain and remove food wastes and grease from the waste stream while allowing the balance of the liquid waste to discharge to the System by gravity. Most of you reading this know that there are different styles of grease interceptors. Hunters Curve doesnt work because it is intended for water flow rates, not drainage.

GRDs are trickier to size than HGIs. Protection Agency", or the authority in charge of the sewerage system into the last fixture serviced, and the inlet of the interceptor. HGIs greater than 500 gallons must have a 60/40 split between compartments. I dont know about you, but, for me, 2016 was a very difficult year, and I am not sorry to see it go. 2.5.5.2 Venting of Oil Interceptors (See Appendix A) (See also Article 4.3.5.2. of Division . not required in garage floor drains in one-, two-, and three-family n3kGz=[==B0FX'+tG,}/Hh8mW2p[AiAN#8$X?AKHI{!7. indicated dishwasher- significant are often of grease water flow and chops the foodSince a food waste grinder into solidified particles, with a cold associated with hot or warm grease laden waste congealing problems is GenerallyManufacturer's good idea to run food recommend a hydromechanicalinterceptor installation, interceptors Does the interceptor require a vent? The service and maintenance cycle for a grease trap or grease interceptor can vary based upon several factors such as capacity, food type, restaurant or kitchen volume, and mandated ordinances. However, since PDI created this procedure, the health departments of the country have mandated indirect waste connections on prep sinks and the like, so drain down time cannot be controlled. The IPC approves the use of and installation requirements for AAVs under section 918.0. Wastewater leaving the grease interceptor must not exceed 300 mg/L of oil and grease and 600 mg/L of solids. Grease interceptors must be selected according to our: The service provider can provide advice on how to configure a solution for your specific situation. TRAP REQUIREMENTS.

The code does allow the interceptor to serve as a trap (assuming that this interceptor is intended to serve as a fixture trap) thus adding a trap to the fixture upstream of the interceptor creates a double trapped fixture installation.

A final requirement is that water flowing through a grease interceptor must not have a temperature above 180F. Both HGIs and GRDs are vented on the outlet. The letter will specify a minimum frequency. Do not use enzymes or other agents that will allow grease to pass through the grease interceptor and into the sewer.

Most inspectors would say yes because the unit itself is trapped and a trap needs a vent, but if you ask the inspectors in Los Angeles City, they would say no, due to the fact that each fixture upstream of the trap is individually vented. Vent the grease interceptor on the inlet side. I am hopeful that 2017 will be much better. If you are designing in the UPC, there is a table in the Code for sizing the interceptors based on pipe size and associated peak flow rate, and then assigns interceptor sizes based on one-minute and two-minute drain down times. {KGGj~]?=^FG.'>rvN_?O%g{ (ye~/^W|_\o\6EU17W2 pM=='.zkZ$b-j`RjFo[n(lw]ot[iQ %[I$tf CtD#"~\An=Chh(3mZP1~GcDn+{*H "4]V4.qAIi`HimHOh1Rc6A- As^3ZX_Q=a6> 75wMw/w[w @4 Y|kf j}`} 2|u}zv&a{e4F;sP|;IR.vuy-S`4y)%)` bc7.
