The oil separator you asked is the equipment of a company in Beijing. The equipment looks like the picture below. The equipment has simple structure, limited treatment effect and relatively cheap price. Generally speaking, it is around 30,000 ~ 50,000!

It is suggested to consider the integrated oil separation lifting equipment produced by Tian Jian, the chief editor of national industry standard. It is also a participant in the national building standard atlas "Selection and Installation of Oil Separation Equipment for Catering Wastewater". The appearance of the equipment is as follows:

Tian Jian brand T3(20 15) series integrated automatic oil separation lifting equipment adopts O-type debris cleaner to automatically clean debris, which has the functions of mechanical and manual double oil discharge, automatic sludge discharge and four-stage process joint control. The management and maintenance are convenient, and the price is only about 20% more expensive than MOSE. I suggest the landlord consider it.
