Final treatment of wastewater sludge in the City of Zagreb
Abstract
Total sludge disposal costs are quite considerable in case of large-size wastewater treatment plants, where they are approximately equal to personnel costs. The problems relating to the Zagreb wastewater treatment plant are methodically analyzed, from the first conceptual design in 1980, to the present day situation. The issue of final disposal of sludge still remains unsolved, which poses a big problem in the operation and maintenance of this plant. Possible procedures for final treatment and disposal of sludge generated at the Zagreb wastewater treatment plant are presented in full detail.
