Analysis on the working process of activated carbon filter cartridge

date:2020-6-14 16:27:11   Number of times:



The activated carbon filter cartridge is made of natural coconut shell, activated carbon and coal activated carbon as the main body, supplemented by edible grade material binder heating and sintering. It is a relatively new replacement product in the air and liquid purification industry integrates adsorption, filtration or catalysis.

The most inner layer of the filter cartridge is polypropylene skeleton, which is used to strengthen the compressive strength of the filter element. There are two layers of polypropylene ultra-fine fiber felt on the skeleton, which can intercept the particles more than 10-20 microns in the liquid, so that the filter element has the dual functions of filtration and purification. The most outer layer is a white plastic net, which makes the filter cartridge have a complete and neat appearance. The two ends are soft butyl rubber end cover, so that the filter cartridge has a good sealing property after being loaded into the filter housing.

Working process of granular activated carbon filter.


The water enters the fixed seat through the inlet of the B-type fixed seat, the channel of the filter core center of the water purifier, and passes through the activated carbon fiber + PP composite filter material. In the process of passing through the filter material, the activated carbon fiber absorbs large particle impurities, organic matter, heavy metals, residual chlorine and other pollutants in the water, so that the purified water of the water gathers in the space between the outer wall of the filter element and the filter core shell, and then flows to the outlet of the filter element fixed seat through the outlet of the shell of the top side. Therefore, the water flow mode is the internal water intake mode. The flow mode is controlled by the fixed seat, which must be taken into account in the design of the filter element. In special cases, activated carbon filter cartridge can also be used with A-type fixed seat.
