Abstract

Treatment of polluted water using novel technology is an effective strategy to sustain the water supply; however, current treatments are not adequate to deal with the pollution problems. Conventional treatment using chlorine generate toxic chlorinated by-products while advanced oxidation processes using ozone have potential to generate suspected carcinogenic bromated ion in water containing bromide ion. Ferrate (FeVIO42-, Fe(VI)) is a suitable green chemistry oxidant and disinfectant and can address concerns of traditional oxidants in order to meet the demand of the water supply in coming decades. The by-products of the application of ferrate(VI) are nontoxic iron oxides and oxygen. The efficiency of ferrate for removing dissolved organic matter is higher than that of traditional coagulants ferric chloride and alum. This chapter summarizes the studies performed on the interaction of ferrate(VI) with natural organic matter (NOM) and role of such interaction in removing inorganic and organic impurities of polluted water. Ferrate preoxidation enhanced the coagulation of NOM. This chapter also presents case studies of the effectiveness of a novel ferrate treatment technology for removal of NOM from river water, lake and stream water, wastewater, and sediments and soil samples.
