Kinetics of biodegradation of sewage due to addition of Chlorides


Presence of salinity 9 to 20 g/L of chlorides can cause osmotic stress or inhibit the reaction pathways in the organic degradation process. It results in a significant decrease in biological treatment efficiency or biodegradation kinetics. Research is carried out using glucose–glutamic acid and domestic wastewater to evaluate the amendment of chlorides on biodegradation of sewage at 20°C. The findings confirm the hypothesis of biological oxidation rate ―k‖ has higher value under presence of up to 6 g/L of chloride concentrations, compared to that of fresh water medium. It was also noticed that improvement of ―K‖ value was more pronounced during the first 3 days of BOD test, a fact that needs further detailing study. These values are of significance for co-treatment of sewage and industrial wastewater containing high salt concentrations.
