Ceramic membranes, also known as inorganic ceramic membranes, are asymmetric membranes formed from inorganic ceramic materials through a special process. They are primarily made from Al, Si, Ti, or zirconia and silicon carbide. Their filtration range covers microfiltration to nanofiltration, and is capable of filtering colloids, pigments, salts, dyes, and other impurities. Additionally, inorganic ceramic membranes have high mechanical strength, excellent resistance to high temperatures, acid and alkali, oxidation, biological corrosion and backwashing, narrow pore size distribution, and high filtration accuracy. Due to their easy cleaning and sterilization, ceramic membranes are easier to clean and more effective than organic membranes, with a high flux recovery rate after cleaning.

Tubular ceramic membrane
Tubular ceramic membranes often use a 'cross-flow filtration' mode to achieve fluid process separation. The feed liquid flows at a high speed inside the membrane tube. Under pressure, the permeate containing small molecules passes through the membrane layer in the vertical direction, while the concentrate containing large molecular components is retained by the membrane. This process achieves the purposes of fluid separation, purification, and concentration.
Flat ceramic membrane
The flat ceramic membrane adopts an outside-in suction filtration mode. The raw material enters from the membrane surface, and under certain pressure, only water, inorganic salts, and other small soluble molecules are allowed to pass through, while suspending large molecules such as suspended solids, colloids, and microorganisms in the water are retained. After filtration, the water flows through the water collection vertical pipes, and is collected in the horizontal collection pipes at both ends of the membrane, and then is extracted by a suction pump to achieve the purpose of separation.
