Ceramic membranes are porous asymmetric membranes made by high-temperature sintering of materials such as alumina and zirconia through special processes.Ceramic membrane equipment is a "crossflow filtration" process for solid-liquid separation. Under pressure, the feed liquid flows through the membrane tubes, where small molecule substances permeate the membrane, while large molecules and solids are retained in the membrane to form a concentrated liquid, achieving the purpose of separation, concentration, and purification of the fluid. The filtration precision of ceramic membranes covers microfiltration and ultrafiltration, with the microfiltration membrane pore size ranging from 50nm to 1.4μm, and the ultrafiltration membrane precision ranging from 8KDa to 50KDa. Different pore size membranes can be selected as needed to achieve clarification and separation. Ceramic membranes have characteristics such as high temperature resistance, resistance to chemical corrosion, high mechanical strength, resistance to microorganisms, high flux, good cleaning recovery, and long service life. They are currently used in fermentation liquid clarification, oil-containing wastewater treatment, garbage leachate MBR, oilfield water injection, juice, fruit wine, vinegar, and more.
