Protection Agency", or the authority in charge of the sewerage system into GRDs are trickier to size than HGIs. Many states that adopt or adapt the UPC have added an allowance for AAVs so you will have to check with your state to see if they are approved. Metro Vancouver respects the diverse and distinct histories, languages, and cultures of First Nations, Mtis, and Inuit, which collectively enrich our lives and the region. This drawing for a PDI G101/ASME Type A grease interceptor appears to be compliant with the IPC. The GI flowline (upstream of inlet invert) must be at least 3 inches above the tanks static water level; The GI vent must be at least 3 inches above the static water level of the tank; The GI inlet must be near an elevation that is one half of the tank's static water level height, and the GI outlet must be at least 12 inches above the tank floor; Adequate flow diffusion features must be provided to evenly distribute flow throughout the GI.

Book -Volume 4, Chapter 8, Grease Interceptors or CSA B481 Series-12 may also be considered. GRDs are similar to HGIs except they have a motorized wheel that skims the floating grease off the top of the waste stream and deposits it in a removable container that makes maintenance quite simple. These large central units are often buried outside or hidden in a parking garage. Fats, oils and grease in the sewer system costs the region over $2.7 million each year.

SPS 382.34(5) - 6/29/01 Is a grease interceptor required for an "auto fry"? This checklist is provided as a reference tool and it is not intended to be exhaustive of all possible plumbing requirements. You would think after being around so long that the plumbing associated with these units would be long established and well defined, but it is not. The unit shown is certified to ASME A112.14.3 Type C (without external flow control) with a built-in or integral flow control and does not require an air intake. As the waste stream flows through the orifice in the flow control device negative pressure is created, drawing in air from the air intake which is intended to mix with the waste water as it enters the grease interceptor aiding in separation efficiency. All exterior interceptors shall be designed and constructed in accordance with this paragraph, so as to constitute an individual structure. What's important to remember about AAVs is that they only allow for the relief of negative pressure in the drainage system. 1046 0 obj

As with the gravity grease interceptors, the sizing of the vent is ambiguous. They can clog sewers and cause back-ups into homes and businesses, and overflows into the environment.

Manufacturer's are required to identify which Type their interceptor is rated to when certifying to the ASME standard. Once the grease interceptor reaches maximum capacity, a certified grease trap cleaning company will need to be called in order to service the grease interceptor. 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. Do not use enzymes or other agents that will allow grease to pass through the grease interceptor and into the sewer. a) All required grease interceptors shall comply with the following: 1) Material and Covers.

Grease and Commercial Kitchens Brochure (English). 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. This very simple concept allows two traps to be vented by the same vent. Most jurisdictions would say no because the interceptor is trapped internally. If such is the case, they should be piped to the vent system and not left plugged, otherwise it may void the interceptor warranty. This installation is compliant with both the IPC and the UPC since it shows a trapped and vented fixture discharging through an approved interceptor without external vented flow control with a vent installed downstream. in size in areas where it may be subject to frost closure. 1014.3 Gravity Grease Interceptors Required gravity grease interceptors shall comply with the provisions of Section 1014.3.1 through Section 1014.3.7 . 2.5.5.2 Venting of Oil Interceptors (See Appendix A) (See also Article 4.3.5.2. of Division . 1093 0 obj

PDI G101 mandates the installation of a vented external flow control. I am hopeful that 2017 will be much better. 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. Therefore, when using an AAV to vent a grease interceptor, it's important that the drainage system has provision for the relief of positive pressure to ensure proper flow. serving chemical waste systems shall not be prohibited. Grease Interceptor. There are no moving parts, but there is a series of baffles that catch the grease in the waste stream creating a hydromechanical process. plants shall be drained in accordance with the rules of the "Ohio Environmental Interceptors and separators shall be designed so as not to become air bound. Grease interceptor. Drain down cant be controlled to two minutes due to the presence of air gaps on many of the fixtures. 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. 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. endstream

For SI: 1 gallon per minute = 3.785 processes, meat packing and food processing facilities and similar processing These take two basic forms, hydromechanical grease interceptors (HGIs) or automatic grease removal devices (GRDs).

@8(r;q7Ly&Qq4j|9 @le&exDxX The retention capacity of grease interceptors (in pounds) must be at least twice the numerical value of flowrate through the unit (in gallons per minute). Generally speaking, most grease interceptors must be serviced at least every 90 days. 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. Model plumbing codes require each fixture discharging into a grease interceptor be individually trapped and vented, and require the installation of a vent downstream of the grease interceptor. 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 Most of you reading this know that there are different styles of grease interceptors. 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.

Either adding a vent to the trap or removing the trap on the fixture altogether would solve the problem. The two traps and their fixture drains can be either at the same level or at different levels, provided that they are on the same floor.

The vent on the flow control is an air intake. the publication as well as the name and address of the promulgating agency are which the wastes are to be discharged. 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 purpose of a grease interceptor is to catch and collect fats, oils, grease, and solids (FOGS) from commercial and restaurant kitchens. PDI G101 and ASME A112.14.3 Type A certified interceptors are required to have a vented external flow control installed upstream of the interceptor. As the waste stream flows through the orifice in the flow control device negative pressure is created, drawing in air from the air intake which is intended to mix with the waste water as it enters the grease interceptor aiding in separation efficiency.
