Oil-water separators are available in both powered and automatic types. The non-powered oil-water separator is typically used for smaller capacity applications and requires simple manual maintenance. Its advantage is that it can achieve oil-water separation without the need for power connection, saving energy and reducing emissions, in line with today's environmental protection concepts. The automatic oil-water separator does not require manual maintenance, features automatic waste water and sludge discharge, and automatically detects the oil-water interface for oil discharge. Its advantage is that it does not require manual maintenance and can achieve visual monitoring capabilities. If installed in a basement, it needs to have lifting functions.
