Three-Step Grease Trap Method

Grease trap: It uses the different densities of suspended solids and water in the wastewater to achieve the separation objective. The structure of grease trap mainly adopts advection type. Oily wastewater enters the rectangular grease trap through the water distribution tank. and flows in the horizontal direction. It flows slowly in the direction, and the oil floats on the water surface during the flow, and is pushed to the oil collecting pipe by the oil collecting pipe or oil scraper installed on the pool surface and drains. in the dehydration tank.

Heavy oil and other sediments deposited in the oil separation tank feeders, accumulate in the sludge hopper at the bottom of the pool and enter into the sludge pipe through the sludge discharge pipe. treated by oil separation overflows into the drainage channel and basindischarge for further processing to remove emulsified oil and other pollutants. Separation The oil basin is equipped with two oil drains on the left and right, one according to the actual conditions of the installation place. The side can be closed and one side can be closed. The oil drain port on one side should be equipped with a valve when draining the oil, open the valve and temporarily close the outlet if necessary. oil level and drain the floating oil.

You can also open the pool cover and skim off the grease with a spoon. The grease trap is equipped with a stainless steel filter, which has a good grill function. Plant residue and debris can be effectively trapped when discharged into the grease trap. Simply use a strainer to catch them.

If there is too much oil on the filter, you can remove the filter and rinse it with hot water and insert it again. Remet it to its original location. Depending on usage, if the surface grease in the grease trap exceeds 5cm, the oil should be drained to the bottom of the grease trap. By installing a valve, they are usually closed. They can be opened when the grease trap is thoroughly cleaned. Valve to drain all the water and mud at the bottom of the grease trap.

Grease traps are divided into. overhead, underground, semi-buried, suspended and automatic according to different installation methods and processing methods. Oil scraping grease trap, automatic air floating oil scraping grease trap, filter type grease trap. >Brick concrete, steel concrete or carbon steel can be used, as well as anti-corrosion epoxy resin coatings and chemical fiber fabrics. For combined use, generally 1 cloth and 2 oils to 3 cloths and 4 oils are used if the requirements are not high. If the requirements arent high and contain a large amount of acid, alkali or other corrosive substances, use 5 cloths and 6 oils. Oil removal efficiency is closely related to residence time and water distribution structure. If the requirements are not high, brick concrete can be used. If the requirements are high, steel concrete can be used. If the water volume is low. efficiency requirements are high, carbon steel structure is required.
