ABSTRACT Next to hardness, the presence of iron is probably the most common water problem faced by consumers and water treatment processionals. The secondary (aesthetic) maximum contaminant levels (MCL) for iron and manganese are 0.3 (mg/l) and 0.05 mg/l, respectively . Iron and Manganese are two of the most abundant elements found in earth’s crust. The oxidized forms Fe+3 and Mn+4are most prevalent, but reduced forms (rhodochrosite) [FeCO3] and siderite [MnCO3] that are present in water]. The existence of iron and manganese in drinking water generates certain unpleasant side effects, such as color, precipitates in water, stains on clothing and plumbing fixtures. The objective of the present study is production of ozone by corona discharge (bench scale, which produce 0.3 mg ozone per minute that sufficient to reduce of ferrous and Manganous ions 2 ppm and 4 ppm respectively to permissible limits of WHO specifications as well as disinfecting of water from microorganisms like Escherichia - Coli, streptococcus -Faecalis and Staphylococcus-Aureus. | ||||
