Iron removal is a problem which occurs with some private (well or borehole) water supplies, and is typically an aesthetic issue - Orange staining on clothing, bathroom tiles and such will usually be evident should your water be excessively high in it.
Pozzani Iron removal systems are all built around the Filox-R media which is designed to remove Iron, Manganese(see note) and Hydrogen Sulphide. Filox-R media removes iron by oxidation requiring a pH between 6.5 and 9 in order to work effectively (in some cases an air pump may be required to assist the oxidation process). The media regenerates through backwashing with plain water each day, and is durable enough to last several years in most correctly configured installations.
Iron removal systems should be installed prior to any chemical disinfection system.
