The main factor that affects the ceramic filtration accuracy is the maximum pore diameter of porous ceramic filter elements. For the same fluid medium, the smaller the pore size, the higher the filtration accuracy, and vice versa. Secondly, the working pressure also has a slight effect on the filtration accuracy.
The larger the pore diameter of the porous ceramic, the higher the porosity, and the larger the working pressure difference, the greater the flow rate. As the wall thickness of the porous ceramic filter increases and the viscosity increases, the flow rate decreases rapidly.
Main Applications of Ceramic Filter Media
Liquid Ceramic Filtration
1) Chemical liquid filtration. It is mainly used in the filtration of acid and alkaline liquids in the chemical industry, molten metal filtration in the metallurgy industry, aviation kerosene in the petrochemical industry, diesel fuel filtration, and filtration of various organic liquids. The investment can reduce by more than 40%, and the efficiency can increase by 2-4 times.
2) Water filtration: mainly used for industrial wastewater treatment, domestic water, mineral water, ultrapure water preparation, etc.
Gas Ceramic Filtration
Mainly used for oil-containing various compressed gases, impurity treatment, chemical catalytic gas fine filtration, sterile air purification in pharmaceutical and brewing industries, and high-temperature flue gas dust removal. Similarly, the use of ceramic filters can also perform water mist separation, gas separation, etc.
In addition, porous ceramic filter elements can also be used as gas distribution materials. Porous ceramic filter elements can also use as gas diffusion elements for various electrolytes, as well as fluidized beds and adhesive transport plates.
With its many advantages, porous ceramics filters can effectively replace traditional filter materials, such as nylon mesh, fiber filter cloth, porous plastics and powdered metallurgical porous materials, etc. It is foreseeable that with the continuous improvement of porous ceramic materials and filtration technology, porous ceramic filters will become self-contained systems, which play a very important role in gas separation, purification and liquid fine filtration.
