Iron & Manganese Removal Industrial Water Treatment

Dissolved iron and manganese are common contaminants that require treatment in potable water and industrial wastewater processes. Problems created by iron and manganese include discolored water, undesirable taste, bacterial growth, and fouling of process piping. The Safe Water Drinking Act sets limits of 0.3 ppm for iron and 0.05 ppm for manganese.

Manganese removal physical-chemical way Lenntech

Manganese does not present a danger to human health, nor for the environment but it is unpleasant. In fact, the water gets a black color and a metallic taste. Similar to iron, the manganese removal by physical-chemical way, can be carried out by the oxidation of Mn 2+ in Mn 4+,which precipitates then in manganese dioxide (MnO 2 ).
