Oxidation Filtration

Oxidation/filtration refers to precipitative processes that are designed to remove naturally occurring iron, manganese, and sulfides from water. The processes involve the oxidation of the soluble forms of these contaminants to their insoluble forms and then removal by filtration of the precipitated particles.

Arsenic may be removed with the iron in some cases. Arsenic can be removed via two primary mechanisms: adsorption and co-precipitation. In groundwater containing both iron and arsenic, they are usually found in their reduced form. For optimum arsenic removal, a chemical oxidant such as sodium hypochlorite is often needed. Oxidized arsenic then adsorbs onto the iron hydroxide particles that are ultimately filtered out of solution. The arsenic removal efficiency is strongly dependent on the initial iron and arsenic concentrations.

The AdEdge Technologies oxidation/ filtration medias have high catalytic and oxidation activity, superior handling properties and stability, NSF 61 certification, require no permanganate or coagulation addition and low capital and operating costs compared to other alternatives due to the smaller system footprints. We have over 300 public water system installations and over 3,000 residential installations, more than any company in the U.S.
