The external pressure filtration device adopts an asymmetrical ceramic membrane made of inorganic ceramic materials through a special process as the filter element, with a pore size of 0.2-10μm, with good chemical stability, acid, alkali and organic solvent resistance, high temperature resistance, strong antimicrobial ability, high separation efficiency, high mechanical strength, long service life and other advantages, suitable for high temperature, high pressure, strong corrosion of organic membranes can not be used under working conditions, can be widely used in petroleum, chemical, medicine, environmental protection and other industries of filtration, purification, sterilization, etc. Process of removing impurities. 

The working principle of ceramic membrane external pressure filtration device 

1. Filtration: 

The device adopts the method of surface filtration mechanism filter cake filtration, during filtration, the filter material is driven into the filter with a pump, and the clear liquid enters the collection pipe through the pore in the support body through the ceramic membrane, and the solids in the material are intercepted on the surface of the membrane to form a filter cake. 

2. Backflush and slag discharge: 

Relying on compressed air to drive the clear liquid for backflush, the liquid instantly reverses the flow to remove the filter cake from the surface of the membrane and sink to the bottom of the filter. 

3. Continuous and reliable operation: 

Filtration, recoil, and slag discharge are controlled by PLC programs, and the cycle is repeated to realize the continuous and reliable operation of the ceramic membrane filter.
