Abstract

This paper studies the efficiency of iron (Fe+2) and manganese (Mn+2) removal from groundwater using oxidation by potassium permanganate followed by filtration and using conventional treatment consisting of flocculation, sedimentation and filtration. Experiments were done for different combinations of Fe+2 and Mn+2 concentrations. The obtained results show that Potassium Permanganate (PP) gives good results. By using PP dose equals to half of the theoretically required one, it can remove up to 100% and 90% of iron and manganese respectively over different tested concentrations at pH=7.0. Increasing rate of filtration decreases the Mn+2 removal efficiency obviously.    Sedimentation is required when combined concentrations of iron and manganese are greater than 5.0 ppm to reduce filter rapid clogging. Using conventional treatment with adding Alum, flocculation, sedimentation and filtration can remove up to 97% and 18% of iron and manganese respectively. Using PP in addition to alum enhances manganese removal but decreases iron removal. However, using Alum with raising pH to 10 leads to 100% and 95% of Fe+2 and Mn+2 removal and increases filter working period
