Assessment of Dissolved Oxygen in SewageContaining Camphor

Camphor is widely used for odor eradication in eateries and homes. The health of the sewage tank is paramount to the environmental engineer as bacteria aid in sewage degradation. This research is geared towards investigating the effects of camphor on aerobic and anaerobic sewage degradation due to its constant usage. Ten 4 liters clean containers having 2 liters sewage where prepared. To one set of four 4 liters containers which was not covered (Aerobic), crushed camphor weighing (7.38g, 14.25g, 21.91g, and 25.75g) were added and the other four 4 liters containers which was not covered (Anaerobic), camphor in solid form (2No., 4No., 6No., and 7No.) with the same weight as described above to check the effects of surface area and two control containers having sewage alone. The pH, Total Dissolved Solid (TDS), Dissolved oxygen (DO) and temperature was observed and compared with a control solution which had no camphor. From the research, dissolved oxygen level showed significant decrease as the weight and number of camphor increased. This could imply that the presence of camphor creates a film over sewage thereby reducing oxygen exchange rate as it was observed during the experimental process. This finding could emerge as one of the reasons for septic tank failures which may arise as a result of increased organic loadings over time. However, the physio-chemical properties which include pH, TDS and temperature
