We conducted analysis of the currently functioning deferrization station. We demonstrate that in some cases stations built in 1950-60-s became obsolete, and technology based on simplified aeration followed by filtration does not ensure required quality of purified water at all times. Moreover, this article provides an example which justifies the development of tech solutions for the reconstruction of the deferrization station. We propose an introduction of new technology with bioreactors and filters with a floating load, use of technological pipelines from non-laminated polyvinyl chloride and energy-saving fittings. Results show that concentration of iron in purified water after the reconstruction does not exceed 0.075-0.084, manganese - 0.025-0.028 mg/l, turbidity is less than 1 FTU, chromaticity is less than 2.8 degrees. Total energy consumption comprises 0.96 kW per hour.
