The primary functions of a restaurant oil-water separator are as follows:

Efficiently removes grease from wastewater, ensuring the smooth operation of the drainage system and preventing blockages and corrosion.

Purify wastewater, remove or reduce pollutants in the wastewater to meet environmental discharge standards, and protect the environment.

Helps in recycling waste oil, reduces reliance on conventional energy sources, and lowers environmental pollution.

Reclaiming and utilizing waste oil can also yield economic benefits, providing the catering industry with an additional source of income.
