Removal of residual chlorine

kdf can remove oxidants in water, such as residual chlorine. This effect is accomplished through an electrochemical redox reaction. In some cases, such as free chlorine, through this chemical reaction, it can be turned into beneficial substances, completely remove chlorine and trihalomethane and other by-products, hydrogen sulfide and other harmful gases in the water, and then pass through the next layer of filtration.

Zn + HOCl + H2O + 2e → Zn2 + Cl + H + 2OH
