Sažetak
In recent years, concern about occurrence and fate of pharmaceuticals that could be present in water and wastewater has gained increasing attention. Pharmaceutical industry wastewater may contain raw materials, catalysts, additants, intermediates, organic solvents and active pharmaceutical ingredients, which makes them difficult to treat. If compared to chemical or physical processes for treating industrial wastewaters containing organic pollutants, biological treatment is the preferred option in terms of economical costs and ecological footprint. Bioremediation process is a green technology, microorganism mediated transformation or degradation of contaminants into nonhazardous or less- hazardous substances. Bioaugmentation is an introduction of specific strain or a consortium of microorganisms with the aim of accelerating and enhancing the removal efficiency of recalcitrant and/or toxic compounds in polluted sites and bioreactors. Inoculating activated sludge with additional microorganisms able to produce versatile enzymes to enhance biodegradability, is gradually considered as a possible solution for the recalcitrance of biorefractory organic compounds, such as active pharmaceutical ingredients. The goal of this study was to investigate the bioremediation efficiency of wastewater from pharmaceutical production. The experiments were conducted in batch reactor under submerged conditions, using bioaugmented activated sludge with isolated mixed bacterial culture. Initial concentrations of biomass, expressed as mixed liquor suspended solids, ranged from 1.15 to 3.96 g dm-3. Initial concentrations of organic matter in pharmaceutical wastewater, expressed as COD, which was used as a substrate, were 5010 mg dm- 3 in Exp.1 and 3475 mg dm-3 and Exp. 2. During the experiments, monitoring of COD, pH-level, concentrations of dissolved oxygen and biomass was performed. Microscopic analyses were performed to monitor the quality of activated sludge. Pharmaceutical wastewater average bioremediation efficiency was 64.9 % and 69.1 % in Exp. 1 and Exp. 2, respectively.
