Alumina Tubular Ceramic Membrane

Alumina tubular ceramic membrane is a porous asymmetric membrane made of aluminum oxide, titanium oxide, zirconium oxide, and other materials through a special process. It is a fluid separation process in the form of “cross-flow filtration”. Driven by pressure, the raw liquid flows in the membrane tube, small molecules pass through the membrane, and the concentrated liquid containing large molecular components is retained by the membrane, so that the fluid can be separated, concentrated, and purified.

Alumina Tubular Ceramic Membrane

The filtration accuracy of ceramic membrane covers microfiltration and ultrafiltration. The filtration pore size range of the microfiltration membrane is between 0.05μm and 1.4μm, and the filtration accuracy range of the ultrafiltration membrane can be between 10KDa-50KDa. Membranes with different pore sizes can be selected according to the viscosity and suspended matter content of the material to achieve the purpose of clarification and separation.

It has the characteristics of high-temperature resistance, chemical corrosion resistance, high mechanical strength, strong antimicrobial ability, large permeability, strong washability, narrow pore size distribution, good separation performance, and long service life. At present, it has been successfully applied in separation processes in chemical and petrochemical, food, biology, and medicine.
