Sažetak
Production of the water-based printing inks, although initiated for strictly environmental reasons, raised some new problems, especially regarding new waste stream treatment. Due to the intensive coloration and loading with organic material conventional treatment methods are not adequate. In this work the possibilities of final treatment of residues after wastewater treatment with bentonites as a natural and cheap treatment material has been studied. The extensive research has been performed to determine optimal pre-treatment system parameters, bentonite types and its concentrations, pH of the system, as well as influence of the ink composition and complexity, and the influence of the filter media. For the parameters where the maximal decolorization extents were achieved, precipitates/residues were analyzed for heavy metal, water and ash content. The behavior of residues itself and their mixtures with natural clay during the thermal treatment was studied. Temperature profile was varied from room temperature up to 1000 &ordm ; ; C because it corresponds to heating profile used in brick production. The behavior of samples was analyzed by differential scanning calorimetry (DSC) and thermal gravimetry (TG). The possibility of adding residues into raw material for brick production have been investigated by preparing model samples with 0.5% to 3.0% of residues in natural clay. Using this approach the highly problematic waste could be managed without any further loading of the environment.
