Efficiency Of The Biological System For Iron And Manganese Removals From Water

Fifty ground water samples were collected from five different localities in El-Sharkia Province Egypt during 2014. Leptothrix discophora W19 was isolated from the collected ground water samples purified and grown on nutrient agar media supplemented with 1mgL of each of iron and manganese. Conventional identification of Leptothrix discophora W19 isolate following the key of Bergeys manual. Standard water containing different concentrations of Fe2 and Mn2 had been examined for both tested metals removal capacity using Leptothrix discophora W19 as a bioleaching. The biological system for iron and manganese removal had provided overall removal efficiency up to 95.25 and 95 for iron and manganese respectively.
