Sažetak
Increase in the world’s population and urbanization, especially in developing countries, leads to higher amount of wastewater. Their discharging without prior treatment can easily cause environmental pollution issues. Biological processes have been widely used for wastewater treatment because of their low cost and effectiveness. Nowadays, biosorption technique is increasingly gaining importance due to the appearance of biologically resistant xenobiotics. Generally, biosorption is a physico-chemical process for removal of substances from wastewater by biological material. In this study the biosorption capacity of activated sludge from pharmaceutical wastewater treatment plant was determined. The initial concentration of activated sludge, with particle sizes 90-125 μm, ranged between 2.82 to 5.98 g L-1 while the initial concentration of substrate was 5.41 g O2 L-1. The toxicity impact index of the pharmaceutical wastewater was TII50 = 84.21. During the experiments, the COD, pH value, electrical conductivity, concentrations of dissolved oxygen and biomass were measured. Microscopic analyses were performed to monitor the quality of activated sludge particles. The highest biosorption efficiency was 25.5 %. No activity of activated sludge was recorded due to microscopic analyses and oxygen uptake rate values which were between 1.62 mg L-1 h-1 and 8.32 mg L-1 h-1.
