The UDF filter element is made of high-quality coconut shell or fruit shell activated carbon, which has a large specific surface volume and strong adsorption capacity.

In the water quality pretreatment system, the UDF filter element can adsorb the residual chlorine that cannot be removed in the pre-filtration to prevent the post-stage reverse osmosis membrane from being oxidized and degraded, and at the same time, it also adsorbs the polluting substances leaked from the pre-stage, and has obvious adsorption and removal effects on odors, colloids and pigments, heavy metal ions, COD and other substances in the water. The SDI value of the RO influent can be further reduced.

The activated carbon particles in the UDF filter cartridge have a very large number of micropores and a huge specific surface area, and have a strong physical adsorption capacity. The water passes through the carbon bed, and the organic pollutants in the water are effectively adsorbed by the activated carbon. In addition, there are some oxygen-containing tube energy groups on the amorphous part of the surface of the activated carbon, so that the organic pollutants in the water passing through the carbon bed are effectively adsorbed by the activated carbon.

UDF filter element is a more commonly used water treatment equipment, as the pre-treatment of water treatment desalination system, it can effectively ensure the service life of the post-stage equipment, improve the effluent quality, and prevent pollution, especially to prevent the free residual chlorine poisoning pollution of the post-stage reverse osmosis membrane and ion exchange resin. The period of use is 3-6 months.
