KDF 85 Media For Iron Removal

Iron removal

KDF process media remove iron from water, either alone or in combination with other treatment technologies used at the point-of-entry.
KDF process media act as catalysts to change soluble ferrous cations into insoluble ferric hydroxide, which is easily removed by regular backwashing.
KDF 85 medium removes more than 90% of iron from groundwater supplies.

Hydrogen sulfide removal
KDF 85 medium eliminates H2S by converting the hydrogen sulfide gas to insoluble sulfide, an inert, harmless precipitant.
When hydrogen sulfide contaminated water enters the KDF filter, the copper in the KDF media loses an electron and the sulfur gains an electron and copper sulfide and water are formed. The copper sulfide is insoluble in water and can be backwashed off the KDF filter media.Periodic backwashing eliminates accumulations of the precipitant from the media bed.

Heavy metals removal
KDF 55, KDF 85 media can remove up to 98% of water-soluble cations (positively-charged ions) of lead, mercury, copper, nickel, chromium, and other dissolved metals.
When filtered through KDF media, soluble lead cations are reduced to insoluble lead atoms, which are electroplated onto the surface of the media. Other heavy metals bond to the media and may be recovered when the exhausted media pass through a copper smelter.
