Determining the effectivеness of removing heavy metals from modified wastewater by coprecipitation and adsorption with CаCO3

This paper presents the results of the research which was based on leachate from landfill of municipal waste and on modified wastewaters. Water was modified by the Method of Standard Addition of the following metals: Ba, Cu, Cd, Fe, Hg, Mn, Ni, Pb, Sn and Zn. Metals have been removed from the modified wastewater by method of coprecipitation with calcium carbonate and by adsorption to calcium carbonate. The goal of the study was to explain and compare mechanisms of the most common processes for purification of wastewater by using low cost materials. Effectiveness of the processes was determined after the statistical analysis of the gathered data.
