Removal of iron and manganese from groundwater
Thread Content
Let’s discuss what methods are available for removing iron and manganese from groundwater
First is the air sparging method, which involves introducing oxygen to cause the iron ions present in water to react with oxygen and form iron oxide suspensions. These suspensions are then filtered using manganese sand in a deferrization unit; this is essentially the method used in most cases
Methods such as aeration, potassium permanganate oxidation, chlorine oxidation, and manganese sand filtration – several approaches depending on the levels of iron and manganese in the water and the degree of purification required
