COMPARATIVE STUDIES REGARDING THE HEAVY METALS IONS AND CONDUCTIBILITY, IN WASTE WATERS FROM SMITHFIELD –PERIAM SWINE FARM, TIMIS COUNTY

Abstract

The aim of this study was to present the results of the investigation for the surface waters pollution with different ions, Ph, electric conductibility and organic substances from Smithfield-Periam swine breeding complex. Concentrations of magnesium, sulphates, sodium and potassium are situated under the limits accepted for the first class of the surface waters in the new system of cleaning. Electric conductivity values are over the limits accepted by STAS for the surface waters in the old cleaning system and framed in standard limits in the new wastewaters cleaning system. Ph of the analyzed wastewaters is framed in the standard of the surface waters for both cleaning wastewaters systems. With the exception of organic substances, the new system of wastewaters cleaning used in the Smithfield–Periam swine farm is better and in the same is avoiding the pollution for surface waters.
