The problem of increased concentrations of iron and manganese compounds usually affects households using a well intake. Iron and manganese removal filters completely get rid of unwanted compounds and all their consequences, such as rusty deposits and unpleasant water odour. Iron removal filters are economical and almost maintenance-free.
Iron removal means conversion of soluble form of iron compounds found in water into insoluble compounds, which are retained on the filtering medium. This technology requires water aeration. As a result of aeration, carbon dioxide is removed and water is saturated with oxygen.
Iron and manganese removal requires precise determination of a water contamination degree. This process uses pre-oxidation. Water aeration initiates the process of iron and manganese precipitation. Contaminants are retained on the filtering medium, which additionally supports oxidation.
Using appropriate filtration media, we can reduce iron and manganese amount without aeration. In case of small exceedances, we can use water softening media. For larger exceedances, ion exchange resins or media regenerated with potassium permanganate should be used.
