In most cases raw water entering the home will contain iron in the +2 ionic state (ferrous) which makes it practically impossible to filter out. CQ-BR Filter Media enhances the oxidation reaction of ferrous iron to ferric iron and produces ferric hydroxide, an easily filtered precipitate.
CQ-BR Filter Media’s physical characteristics make it an excellent filter for removing the precipitate once formed. Simple backwashing of the filter system will then remove the precipitate from the CQ-BR Filter Media bed.
Testing for iron and manganese in water
Iron — To test for total iron in water, meaning both ferrous iron and ferric iron at the same time, most testing systems will require conversion of all ferric iron to the ferrous state first. The Visual Iron Test Kit offered by the makers of SenSafe Test Kits does an excellent job of converting all ferric iron to ferrous iron and then detecting the amount of iron in a water sample. Detection Range: 0.01 ppm to 5.00 ppm
Manganese — One testing option, SenSafe Manganese Check allows users to test for dissolved manganese in water in concentrations between 0.02 ppm and 2.0 ppm in under 3 minutes and eliminates interferences from several common ions such as copper, iron, cobalt, lead, nickel, and others.
