Iron or manganese bacteria is a common problem when there are elevated levels of iron or manganese in water. Sorry, preview is currently unavailable. To remove iron and manganese from drinking water, treatment studies were carried out with chlorine and KMnO4 as oxidants. This is due primarily to the fact that iron and manganese can be present together, they can be present in several forms, and each form of iron in water can potentially require a different method of removal. Iron and/or Manganese Reduction. Mn removal is necessary and often has major implications for treatment train design. 0000035103 00000 n Manganese does not present a danger to human health, nor for the environment but it is unpleasant.
