The recommended levels of 0.3 mg/L Fe and 0.05 mg/L Mn correspond to concentrations above which iron and manganese will cause problems such as colored water, staining and taste. This can lead to discoloration in laundered goods, “black” water, water main incrustation, deposits on industrial equipment and debris at the water tap.
Though chlorine can be used to control these problems, it reacts so slowly that iron and manganese ions may still remain in the water distribution system after 24 hours and can reach the end user. Chlorine dioxide and ozone react much more rapidly with iron and manganese, oxidizing them to ferric hydroxide and manganese dioxide solids. The Fe and Mn compounds are then removed by filtration.
