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

Effectively removes oils from wastewater, ensuring the drainage system remains clear and preventing blockages and corrosion.

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

Facilitates the recycling of waste oil, reduces dependence on conventional energy sources, and minimizes environmental pollution.

Recycling used oil can also yield economic benefits, providing an additional income source for the catering industry.
