COMPARATIVE STUDIES REGARDING THE HEAVY METALS IONS AND CONDUCTIBILITY, IN WASTE WATERS FROM SMITHFIELD –PERIAM SWINE FARM, TIMIS COUNTY
Keywords:
pollution, swine, pH, ions, wastewatersAbstract
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.
