Sažetak
In this paper, the results of wastewater treatment (water before treatment in Krofta flotation clarifier, after flotation and pasing through sand filters) in the company of papermaking PAN, Croatia, are presented. The results obtained after removal with clinoptilolite-rich tuff were compared with removal of heavy metals by means of coagulation with iron (III) chloride and using activated red mud. The results proved that iron (III) chloride and activated red mud are more efficient in removal of metals from wastewaters. It is to assume that wastewater of paper industry contain complex agents which bind a paper of meta ions and that way influence efficiency of ion exchange on zeolite.
