What exactly is ceramic membrane?

Ceramic membrane, also known as inorganic ceramic membrane, is named after the use of inorganic ceramic materials. A solid film is formed by using inorganic ceramic materials of different specifications, such as alumina, zirconia, titania and silica, as a support, coating the surface thereof and firing them at a high temperature.
The pore size of ceramic membranes is mostly between 0.8 nm and 1 micron, and they have a three-layer structure of "porous support layer, transition layer and separation layer" with asymmetric distribution, which are all produced for better filtration and separation.
Among them, the flat membrane is widely used, mainly for small-scale industrial production and laboratory research; the tubular membrane combination is similar to the tube and tube heat exchanger, which can increase the filling and accumulation of the membrane. However, due to its strength problems, it has gradually withdrawn from industrial applications.
The work of ceramic membrane is to make the raw material liquid flow at high speed in the membrane tube, and the clear permeate containing small molecular components will pass through the membrane in the vertical direction under the drive of pressure. At the same time, the turbid concentrate containing macromolecular components will be retained by the membrane, allowing the fluid to be separated, concentrated and purified.
