Abstract
This article discusses ways to intensify the natural water treatment plants operation using foamed polystyrene as a contact and filtering medium for bioreactors and filters. The reagent schemes with polystyrene foam filters are offered for the surface water treatment. The improved physicochemical and biological methods for slightly acidic and neutral groundwater preparation are recommended to use. The use of ferrobacteria metabolism products for the ammonium nitrogen oxidation in a slightly acidic medium was investigated. The x-ray spectral analysis of bio-minerals matrix structures was conducted. The reasons of unsatisfactory technical condition of sewage treatment plants in Ukraine were analyzed. The ways of increasing their work efficiency using sedimentation aerotanks of large hydraulic height and using the simultaneous nitrification-denitrification were offered.
