Brief introduction of ceramic membrane:
Ceramic membrane is an inorganic membrane, which belongs to the solid membrane material in membrane separation technology. It is mainly made of inorganic ceramic materials with different specifications, such as alumina, zirconia, titanium dioxide and silicon dioxide, which are coated on the surface and fired at high temperature. Commercial ceramic membranes usually have three layers (porous support layer, transition layer and separation layer), which are asymmetrically distributed. Their pore sizes range from 0.8 nm to 1 micron, and their filtration accuracy covers microfiltration, ultrafiltration and nanofiltration.
According to the different supports, the structure of ceramic membranes can be divided into three types: flat plate type, tubular type and multi-channel type. Ceramic membrane is acid and alkali resistant, high temperature resistant, and has good chemical stability in extreme environment. The pore size of commercial ceramic membrane is small (usually less than 0.2μm).
Molecular filtration can be successfully realized, so it is mainly used for filtration and separation of liquid and gas mixture, and can replace traditional separation technologies such as centrifugation, evaporation, rectification and filtration, so as to improve product quality and reduce production cost. It has broad application prospects in harsh environments such as petroleum and chemical industry.
