Wastewaters, which contain heavy metals, are one of the main sources of environment pollution. This paper presents the data of research findings concerning the combined use of thermally modified organo-mineral waste products of sugar production and brewing industry for purifying test solutions from copper and nickel ions. The most efficient is the sorption material, obtained by heat treatment of brewing industry’s kieselguhr sludge KS450 (94% for nickel ions and 95% for copper ions); the next efficient is the material, obtained from sugar industry’s carbonaceous sludge CS600; the application of combined sorbents showed no increase in wastewater purification efficiency.
