Ceramic membrane is called Chinese inorganic ceramic membrane, which is an asymmetric membrane formed by inorganic ceramic composite materials, which can be designed and manufactured by special treatment process. Ceramic membranes are divided into tubular ceramic membranes and planar ceramic membranes. CT membrane is not another name for ceramic membrane. The name is actually an abbreviation of ceramic membrane, which is misunderstood by non-professionals.
The wall of the tubular nano-ceramic membrane has micropores. Under the action of pressure, the raw material flows in the membrane tube or outside the membrane tube, the small molecule provides the substance (or liquid) through the membrane, and the large molecule chemical substance (or solid) is blocked by the membrane to realize the separation of China. Centralize, purify and protect environmental information. There are micropores on the surface of the planar ceramic membrane, and the molecular diameter and permeability of the substances permeating in a specific pore size range are different. The pressure differential across the membrane is the driving force, and the membrane is the filtration medium.
When the material flows through the membrane surface under a certain pressure, it can only prevent water, inorganic salts and small molecules from passing through, but not suspended solids, adhesives, microorganisms and other molecular substances from passing through the water.
Ceramic membrane has the advantages of high efficiency, stable effect, stable chemical structure, acid and alkali resistance, organic solvent resistance, bacteria resistance, high temperature resistance, pollution resistance, mechanical design strength, regeneration performance, simple separation and development process, etc. It has many advantages such as low energy consumption, convenient operation and maintenance, long service life, and has been successfully applied in food, beverage, meal and other fields.
