What is a ceramic membrane?

Ceramic membrane is a kind of inorganic membrane. It is a solid membrane material in membrane separation technology. It mainly uses inorganic ceramic materials of different specifications such as alumina, zirconium oxide, titanium oxide and silicon oxide as supports. After surface coating and high temperature

Made by firing.

Commercial ceramic membranes usually have a three-layer structure (porous support layer, transition layer and separation layer), which is asymmetrically distributed. Its pore size ranges from 0.8nm to 1μm, and its filtration accuracy covers microfiltration, ultrafiltration and nanofiltration levels.

.

Depending on the support body, the configuration of the ceramic membrane can be divided into three types: flat plate, tubular, and multi-channel.

Due to its acid and alkali resistance, high temperature resistance and chemical stability in extreme environments, and because the pore size of commercial ceramic membranes is small (usually less than 0.2μm), it can successfully achieve molecular level filtration, so it is mainly used for

Filtration and separation of liquid and gaseous mixtures can replace traditional separation technologies such as centrifugation, evaporation, distillation, and filtration to achieve the goals of improving product quality and reducing production costs. It has broad application prospects in harsh environments such as the petroleum and chemical industries.
