Babenko S. Thin-layer element of the improved design for removing suspended solids from water

The object of researches is the process of removing the suspended solids from the water in the thin-layer settling tank. Subject of researches is the working parameters of the thin-layer elements of improved design. The aim is scientific substantiation and improving the design of the thin-layer element which ensure the required effect of water purification from suspended solids. Experimental researches were performed in the laboratory on the pilot plant using a model suspension. To determine the reliability of theoretical studies were used the methods of mathematical statistics. In the thesis the following new scientific results were received: the theoretical relations, that take into account structural conditions of supply and divert of water, separation of clarification zone on two levels and features of the formation of a sediment layer were received on the basis of developed mathematical model of water clarification in the thin-layer element of improved design; the main results of the theoretical calculations of the influence of the thin-layer element structural parameters on the cleaning effect were experimentally studied and confirmed; structural parameters of a thin layer element of the improved design for water clarification were scientific substantiated and determined. The results of the thesis are accepted for the implementation in CE "Kharkivvodokanal" and used in the development of the Institute JSC "Kharkiv Vodokanalproekt". In addition the results can be used by the project and operational organizations to intensify the process of industrial and surface storm water overflows clarification.
