Prospective directions for the development of water treatment systems with surface water sources in the context of global climate, anthropogenic and socio-economic changes in Ukraine

Traditional water treatment technologies in Ukraine, based on aluminium coagulants and chlorination, are effective for turbid waters but ineffective against organic pollutants, in particular phytoplankton (cyanobacteria) in the Dnieper reservoirs.Global climate change and anthropogenic factors (phosphates, pesticides) lead to water 'blooming', an increase in phytoplankton biomass to 10 million tonnes in the Kremenchuk reservoir, and the appearance of toxins (microcystins).Forecast for 5-7 years: phytoplankton concentration >200,000 cells/cm.It is proposed to reconstruct facilities using chlorine dioxide (ClO) and methods of preliminary phytoplankton removal to ensure water quality for 70% of the population of Ukraine.
