Abstract
<jats:p>Small amounts of iron and manganese are quite common in domestic water supply because of the presence of iron and manganese in the soil and rock formations through which the water passes in reaching the point of use. Iron and manganese is characterized by red-brown staining of bathroom fixtures and laundry, and cause taste and odor problems. Iron and manganese are brought into solution by biological reactions under anaerobic reducing conditions. When the water is exposed to air or oxygen, oxidation of iron and manganese occurs slowly, forming objectionable colloidal precipitates. The deposition of these precipitates will stain plumbing fixtures, interfer...
