kdf filter material water treatment function and principle (2.remove heavy metals)

By Zhao from Onlyzone,a manufacturer of water treatment bio ceramic ball filter media in China.

kdf filter media can remove up to 99% of inorganic water-soluble heavy metals, such as lead, mercury, copper, nickel, cadmium, arsenic, antimony, aluminum and many other soluble heavy metal ions. Through the electrochemical redox reaction and catalysis, it precipitates on the surface of the filter material, thereby effectively removing it from the water.

Zn/Cu/Zn + Pb(NO3)2 → Zn/Cu/Pb + Zn(NO3)2Zn/Cu/Zn + HgCl2 → Zn/Cu/Hg + ZnCl2
