Sažetak
The pharmaceutical industry is experiencing a significant increase in production and resulting in wastewater that can pose a hazard to the environment. Bioremediation, as a viable alternative to conventional wastewater treatment technologies, exploits microorganisms for the degradation and / or detoxification of present pollutants. Bioaugmentation, as a strategy for increasing the efficiency of the biodegradation process, implies inoculation of exogenous microorganisms into the wastewater treatment system. In this study, bioremediation of pharmaceutical wastewater by activated sludge, which was bioaugmented with bacterial culture Pseudomonas putida, was investigated. The experiment was conducted during 24 hours in batch reactor at initial concentration of substrate So=5.0 g L-1 and different initial concentrations of bioaugmented activated sludge, Xo=3.7-5.8 g L- 1. During the process, concentration of dissolved oxgen and pH-value were monitored.The quality of bioaugmented activated sludge flocs was monitored by microscopic analysis. The Endo-Haldane kinetic model was used for performing the biodegradation of pharmaceutical wastewater. Estimated values of biokinetic parameters μmax, Ks, Ki, Y and kd were 0.44 h-1 ; 65.53 g L-1 ; 143.63 g L-1 ; 0.45 g g-1 ; 0.0071 h-1. The efficiency removal of substrate was 80 %.
