Sažetak
Since discharge limits are becoming stricter for industrial wastes, there is an intensive searching for efficient and economical methods of pollution reduction. The polymer-induced flocculation process was described as the suitable treatment method for wastewater highly polluted by reactive dyes. According to the preliminary tests, in which many flocculants were studied on two types of model reactive dyes wastewaters, a commercial cationic flocculant Levafloc R was shown as most successful flocculating agent for dyes removal. The optimum pH range and flocculant concentration was found. As the effect of mixing parameters on the process was significant, the optimum combination of the initial rapid mixing intensity, and duration of mixing in given flocculation tank geometry was determined as well.
