Ceramic Membranes Have Good Acid, Alkali, High Temperature Resistance

Inorganic tubular ceramic membranes are precision ceramic filtration materials with a porous structure formed by high-temperature sintering of alumina, titanium dioxide, zirconia, etc. The porous support layer, transition layer, and microporous membrane layer are asymmetrically distributed, and the filtration accuracy covers microfiltration, ultrafiltration, and nanofiltration. Ceramic membrane filtration is a form of "cross-flow filtration" fluid separation process: the raw material liquid flows at high speed inside the membrane tube, and under pressure, the clarified permeate containing small molecular components passes through the membrane in a direction perpendicular to it, while the turbid concentrate containing large molecular components is retained by the membrane, thereby achieving the purpose of fluid separation, concentration, and purification.
