Applicability of development of technology using bioreactor and floating media filter is shown. The technology is based on the biological oxidation of iron and manganese by a group of iron oxidizing bacteria (IOB). The description, the operating principle and the results of technology testing are given. If the content of iron is 4,9-5,71 mg/L, manganese - 0,12-0,2 mg/L and carbon dioxide and hydrogen sulphide are present, the quality of treated water meets all normative requirements. A microscopic analysis of the backwash water from bioreactor and filter was carried out. It has been established that Leptothrix type iron oxidizing bacteria are involved in the oxidation of compounds of dissolved forms of iron and manganese.
