Sažetak
The objective of this study was to achieve better efficiency of phosphorus removal in an enhanced biological phosphorus removal process upgrading the system by different amounts of natural zeolite addition. The system performance for synthetic wastewater containing different carbon sources applied at different initial concentrations of phosphorus, as well for municipal wastewater, was investigated. Natural zeolite addition in the aerobic phase of the anaerobic/aerobic bioaugmented activated sludge system contributed to a significant improvement in phosphorus removal in systems with synthetic wastewater and fresh municipal wastewater. Improvement of phosphorus removal with regard to the control reactors was higher with the 15 g / L than with the 5 g / L of natural zeolite addition. In reactors with natural zeolite addition with regard to the control reactors a significant higher decrease of chemical oxygen demand, ammonium and nitrate, higher increment and better-activated sludge settling were achieved, without changes in the medium pH-values. It was shown that the natural zeolite particles are suitable support material for the phosphate-accumulating bacteria Acinetobacter calcoaceticus (DSM 1532), which adsorbed themselves on the particle surface, resulting in increased biological activity of the system. The mechanism of phosphorus removal in a system with bioaugmented activated sludge and natural zeolite addition was: metabolic activity of activated sludge, phosphorus uptake by phosphate-accumulating bacteria adsorbed on the natural zeolite particles and suspended in solution, and phosphorus adsorption on the natural zeolite particles.
