Role of biosorption in the activated sludge process for pharmaceutical industrial wastewater treatment

The manufacture of pharmaceutical products generates wastewater that contains a variety of specific contaminants. The application of biological treatment with activated sludge is a commonly used process in industrial wastewater treatment with the aim of removing organic compounds through the combination of biosorption process and metabolic reactions of microorganisms. The mechanism of the biosorption process is a physicochemical phenomenon in activated sludge that involves both adsorption of organic matter on the cellular structure and storage of soluble organic matter within the cells. The biosorption process plays a key role in the rapid removal of organic compounds in the early stages of biological wastewater treatment and occurs within a short period of time. In this study, the role of biosorption in activated sludge process for pharmaceutical wastewater treatment was investigated. The biosorption experiments were carried out to study the binding of contaminants from wastewater with different initial concentrations of activated sludge. The optimum initial concentration of activated sludge for the biosorption process of contaminants from pharmaceutical wastewater was 5.12 ± 0.13 g/L. By increasing the initial concentrations of the activated sludge, the specific surface area of the sludge increases, which allows better sorption of sorbates. The average value of biosorption process efficiency was 25.55 ± 10.62%, while the average value of toxic compounds removed was 41.14 ± 10.06%.
