Diatomite Filtration for Removal of Iron and Manganese
This study found that the use of diatomaceous‐earth filters for iron removal was feasible both practically and economically. They will also remove manganese, but with shorter runs. Pressure filters were comparable with vacuum filters in removing iron and manganese. The use of magnesium oxide reduces the chemical and body feed costs considerably. Indicated costs for diatomite and magnesium oxide are $13‐15/mil gal. Filter costs are estimated at $30,000‐$60,000/mgd depending on the degree of automation and the type of filter. John D. Hem follows the article with a discussion on maintaining a sufficiently high oxidation potential (Eh) and pH throughout the treatment system so that iron and manganese will be oxidized and kept that way.
