Ecological Systems and Devices Annotation << Back Estimation of filtration through permeable causeway treatment plant Kuznetsov G.I. Balatskaya N.V. Filippov R.A. The calculated and theoretical substantiation method filter cleaning waste solutions. The method consists in a multi-stage filtering waste solutions through a cascade of filter dams, slopes that fit filters from naturally occurring materials that can remove toxic compounds from the filter solution. The authors propose a simplified method of calculation of stationary filtration in homogeneous undrained dike for water resistance and calculation of filtration using a computer simulation based on the method of finite differences. Comparative analysis of the results obtained by the proposed design method and computational modeling shows that the position of the depression curve and flow filtration practically coincide discrepancies do not exceed 5 %. Experimental and numerical study of the proposed method of cleaning solutions, is currently used in the design of one of the existing facilities.
