A review of biological aerated filters for iron and manganese ions removal in water treatment

Water contains iron (Fe) and manganese (Mn) that can be difficult to remove by singular physico-chemical methods This review paper focuses on the potential of biological aerated filter (BAF) technology for the simultaneous removal of Fe and Mn. It also covers the chemical properties of the respective metals, the causes and effects of high Fe and Mn, and other removal technologies including conventional and advanced treatment methods Surface...
