Iron & Manganese Removal

Iron is one of our most plentiful resources, making up at least 5% of the earth’s crust. Manganese is naturally occurring in ground and surface water and in soils that may erode into these sources. Usually found in water containing iron, manganese makes up approximately 0.1% of the earths crust. Even small amounts of iron & manganese under regulated limits can cause discoloration, poor taste, foul odor, or deposit build up and therefore need treatment. Next to hardness, the presence of iron is probably the most common water problem faced by consumers and water treatment professionals.

Filtronics designs a simple, proven and cost-effective iron & manganese removal systems based upon influent quality, economics and space management. The filter vessel contains Electromedia® I. A media specifically designed for iron and manganese removal. Its adsorptive surface attracts iron and manganese ions and holds them in the bed. The oxidation of iron and manganese is quite rapid. The reaction with water to form hydroxides or precipitates (filterable substances) requires significant times. Iron requires approximately 20 minutes for a complete reaction to a filterable precipitate at pH of 7 to 8. Manganese requires an hour or more to complete the reaction. The adsorptive qualities of Electromedia® I hold the iron and manganese ions in the filter bed and permit this reaction to occur as the water passes through the filter.

Filtronics uses only ANSI/NSF Standard 60 and ANSI/NSF Standard 61 compliant media.
