Dear Mr.Chris Riley
Good question for save environment,
A grease trap, which is usually made of hard plastic, fiberglass or concrete and placed inside the kitchen or buried underground, is therefore very important when it comes to reducing the impact of our existence to the environment. When grease from foodchains, restaurants and even from residential kitchens get into the ocean unmitigated, it would have the effect similar to an oil spill and that is why water waste management system is enacted to control this effect. But without grease traps, water waste management will have a hard time controlling the influx of FOG thus, this technology is indeed our first line of defense and without it, the price that we will have to pay will be great.
1.A good grease trap must slow down the passing of wastewater so that the greasy waste has time to separate out. This means that it should be able to hold all the wastewater of the kitchen at the time that it is heavily used for as long as 20 minutes ( an example of this is the Watts WD-20 grease trap which has a flow rate of 20 GPM). The capacity of your grease trap should not be smaller than 55 gallons and if there are lots of fixtures that you want to attach, you should opt for a bigger one.
2. The length of the trap should be twice its depth. You have to remember that the content of the trap usually occupies 2/3 of its total depth and the remaining 1/3 is head space. When making this measurement, the thickness of the wall should not be included.
3. The total surface area of the trap should be between 1000 to 2000 times its total depth measured in millimeters. Again wall and cover thickness should not be included in measuring this.
4. So that the wastewater and the greasy top layer will not mix, there has to be a baffle at the inlet of the trap which will slow down the flow of water coming in. The inlet pipe should be bent 90 degrees downwards so that incoming water will terminate below the trap.
5. You should provide proper access to your grease trap. This means that covers should be easy to lift up during maintenance. You should provide proper signs especially if your grease trap is an under-floor type so that people will know of its locations. You should also provide indicators for liquid depth and maximum allowable grease layer. When maintenance time comes, you should put barrier around the grease trap when it is opened.
