Ceramic membranes are porous asymmetric membranes prepared from materials such as alumina, titanium oxide, and zirconia through special processes.
Ceramic membrane filtration is a fluid separation process in the form of "cross-flow filtration". Driven by pressure, the raw liquid flows in the membrane tube, with small molecules passing through the membrane while the concentrated liquid containing large molecules is retained by the membrane, thereby achieving the purpose of liquid separation, concentration, and purification.
The filtration accuracy of ceramic membrane is generally based on microfiltration, and the commonly used filtration pore size is 50-800nm.
