Iron filters (such as a manganese greensand filter) are a common treatment for red-water iron levels up to 10-15 mg/L. Aeration (injecting air) or chemical oxidation (usually adding chlorine in the form of calcium or sodium hypochlorite) followed by filtration are options if iron levels are more than 10 mg/L.
