Activated carbon filter as a kind of tank filter equipment, the shell is generally stainless steel or fiberglass, and the interior is filled with activated carbon, which is used to filter the free matter, microorganisms, and some heavy metal ions in the water, and can effectively reduce the color of the water.

· It can be used as a pre-treatment water treatment and desalination system to adsorb the residual chlorine that cannot be removed from the pre-filtration, effectively guarantee the service life of the post-filtration equipment, improve the effluent water quality, and prevent pollution, especially the free residual chlorine poisoning pollution of the post-reverse osmosis membrane and ion exchange resin. At the same time, it also adsorbs polluting substances such as small molecule organic matter that leaks from the previous stage to the water odor, colloid and pigment, heavy metal ions have a more obvious adsorption removal effect, and also has the effect of reducing COD.

· Widely used in food, medicine, electronics, chemical, industrial wastewater and other industries.
