When ion exchange resin is used in the electronic industry, if these organics enter the equipment, the resin will be polluted by organics. If they enter the fine filtration membrane separation, the precision filter will fail in advance. Therefore, in order to reduce the content of organics, chlorine is added in the pretreatment and maintain a certain amount of residual chlorine.

Natural water contains many organic substances. In order to prevent the residual chlorine from harming the ion exchange resin and separation membrane for subsequent treatment, it is also necessary to consider the removal of residual chlorine. Therefore, both organic matter removal and residual chlorine removal should be considered in water treatment, Activated carbon Filters are a good choice.

Activated carbon The filter is a kind of commonly used water treatment equipment. As the pre treatment of the water treatment desalination system, it can absorb the residual chlorine that cannot be removed in the pre filtration, which can effectively ensure the service life of the post filtration equipment, improve the effluent quality, prevent pollution, especially prevent the free residual oxygen poisoning pollution of the post reverse osmosis membrane, ion exchange resin, etc. At the same time, it also absorbs small molecule organics and other polluting substances leaked from the past level, and has obvious adsorption and removal effect on odor, colloid, pigment, heavy metal ions, etc. in water.

The principle of activated carbon to remove residual chlorine: the oxygen containing functional groups in the porous part of activated carbon react rapidly with the oxidizing hypochlorite in water to remove the oxidizing hypochlorite. The size of activated carbon particles has an impact on the adsorption capacity. Generally speaking, the smaller the activated carbon particles, the larger the filtration area.
