It is widely used in food, pharmaceutical, electronics, chemical, industry waste water and other industries.

    The main function of activated carbon filter is to remove macromolecular organic matters, iron oxide and residual chlorine. This is because organic matter, residual chlorine and iron oxide can easily make ion exchange resin poisoning. Residual chlorine and cationic surfactants, not only can make resin poisoning, but also destroy membrane structure, make reverse osmosis membrane failure.

    Active carbon adsorption principle is: in the surface of the particles form a layer of balance surface concentration, then absorb the organic material into active carbon, ensure its high adsorption effect at the early stage. But the active carbon adsorption ability will abate subsequently, so is the adsorption effect. If the water quality in aquatic box is cloudy and the organic matter content in water is high, activated carbon will soon lose filter function. So, activated carbon should be regularly clean or replace.
