Peremitko Illia, student of the “Anatoliy Lyhun Technical Lyceum” (Kamyansk City, Dnipropetrovsk Region), will represent Ukraine at the international final of the Stockholm Junior Water Prize with project "Improvement of domestic wastewater treatment system". This research project is dedicated to studying the question of the efficiency of domestic wastewater treatment from nutrients. The process of wastewater treatment at the treatment facilities in Kamyanske, Dnipropetrovsk region were analyzed. Recommendations were developed for optimizing the operation of domestic wastewater treatment and for stabilizing the processes to reduce the content of nitrogen and phosphorus compounds in treated wastewater.
