There are generally three levels of grease trap, the first level is the joint, and the second level is the grease trap. The kitchen grease trap should be correspondingly larger, generally 2000* 1000* 1200. Remember that the grease trap is generally three stages, the first stage is the joint, and the second stage is the grease trap. The grease trap in the kitchen should also be enlarged accordingly.
The oil separation tank is generally designed as advection, with the minimum design length-width ratio of 4: 1, and is generally divided into 2-4 compartments, each of which is less than 6m in length and 2m in design water depth. The grease trap should be equipped with oil scraper or oil suction pipe to remove the accumulated oil floating on the surface in time.

Grease trap:
The purpose of separation is achieved by using the different specific gravity of suspended solids and water in wastewater. The structure of grease trap mostly adopts advection. Oily wastewater enters the rectangular oil separation tank through the water distribution tank and flows slowly along the horizontal direction. During the flowing process, the oil product floats to the water surface, is pushed into the oil collecting pipe by the oil collecting pipe or the oil scraper installed on the tank surface, and flows into the dehydration tank.
Heavy oil and other impurities precipitated in the oil separation tank gather in the sludge hopper at the bottom of the tank and enter the sludge pipe through the sludge discharge pipe. After oil separation, the wastewater overflows to the drainage tank for subsequent treatment to remove emulsified oil and other pollutants.
