An Iron Removal Plant (IRP), also known as an Iron Removal System or Iron Filter, is a water treatment system designed to remove iron and other impurities from water. Iron is a common contaminant found in water sources, especially groundwater, and it can cause various issues such as metallic taste, staining of fixtures and laundry, and clogging of pipes and appliances.
An IRP typically consists of one or more filtration units that utilize various methods to remove iron from water. The most common types of filters used in iron removal plants include:
Media Filters: These filters contain a bed of filtration media such as manganese dioxide, green sand, or anthracite coal. As water passes through the filter bed, iron particles are trapped and removed.
Oxidizing Filters: These filters use an oxidizing agent, such as chlorine or potassium permanganate, to convert dissolved ferrous iron (Fe2+) into ferric iron (Fe3+). The ferric iron then precipitates out and can be filtered or settled.
