Mechanism of Chlorine Catalytic Oxidation
Manganese ions in raw water are removed by being oxidized by sodium hypochlorite using manganese dioxide on the filter media surface as a catalyst, then adhering to the filter media as manganese dioxide. Caution is required as the filter media becomes inactive if the sodium hypochlorite concentration in the water becomes insufficient.
Mechanism of Air Catalytic Oxidation
This contact oxidation filter media utilizes dissolved oxygen without employing oxidizing agents such as sodium hypochlorite. By avoiding chemical use, it helps reduce operating costs. It is also effective in environments where residual chlorine in treated water is undesirable.
