Ceramic membranes have outstanding advantages such as corrosion resistance, high mechanical strength, narrow pore size distribution, and long service life. They have attracted widespread attention at home and abroad and have been used in many fields. Ceramic membrane treatment of oily wastewater has stable operation, high flux, good effluent quality, and oil content of less than 10 ppm. The ceramic membrane equipment has a small footprint, does not consume chemicals and does not generate new sludge during normal work, and the quality of recovered oil is relatively good. It has increasingly shown its strong competitiveness in the field of oily wastewater treatment.
