Specifications 85% Chlorine Reduction : 82,000 Liters @ 20 LPM 85% Iron/Manganese Reduction : 40,000 Liters @ 20 LPM Manufactured by CaWare #IBC Series To know more about how the IBC effect for Iron removal : #IBC altered the media blend in carbon block which us the most sophisticated catalytic water filtration media with extremely high capabilities of removing both Iron (Fe) and Manganese (Mn) simultaneously through catalytic oxidation and retention of precipitate. The plus claiming is also remove arsenic from a water supply given the correct conditions. Catalytic Filter Media : The catalytic filter media is to boost oxidation capacity of low cost oxidant such as NaOCl. (Before the filter you inject oxidant.) Iron and manganese in solution are in the form of lower valence oxi-hydroxides (example, ferrous hydroxide). Higher valence oxi-hydroxides (ferric hydroxide, red color) are not soluble in water around neutral pH. When the water with iron and manganese in solution and oxidant reaches the filter bed, the low valence hydroxides oxidize to high valence; insoluble form and precipitated particles are retained in the filter bed. This process would take place normally in a matter of days to weeks. The catalytic filter media makes this happen in minutes accelerating the reaction a few hundred times.
