The impact of the Simferopol wastewater treatment system on the chemical and physico-chemical parameters of the Salgir River water

Summary

Based on the analysis of the impact of the Simferopol wastewater treatment system on the changes in the chemical and physico-chemical parameters of the Salgir River water, possible diverting a part of the water source flow to ensure sustainable water supply has been demonstrated. As a result of the failure at the Kakhovka Reservoir hydraulic structure, supplying water from the Dnieper by gravity is currently impossible. Therefore, a comprehensive feasibility study is needed to use the Mezhgornoe off-river storage reservoir by diverting a part of the Salgir River flow. The carried-out analysis showed that generally the efficiency of the Simferopol wastewater treatment system is satisfactory. Considering the high pollution level of the river upstream the effluent discharge point some slight pollution in terms of suspended solids and total iron (COD) caused by the effluent discharge was detected. The Simferopol wastewater treatment system produces a negative impact on the water quality of the Salgir River in terms of the ammonium and nitrite ion levels. The carried-out analysis forms the basis for a feasibility study for design solutions on using the Mezhgornoe storage reservoir for water supply by diverting a part of the Salgir River flow.
