Effect of detention time on aerobic stabilization pond performance in Southeast Asia Bangkok : Asian Institute of Technology, 1968 53 p. Thesis ; no. 196 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering in the Asian Institute of Technology, Bangkok, Thailand Thesis (M.Eng.) - Asian Institute of Technology, 1968 The performance of aerobic ponds at different detention times was investigated. Performance under indoor and outdoor conditions were compared. Both studies showed better removals at longer detention times. In the first run, with an influent BOD of 50 mg/1, both laboratory and outdoor ponds were successfully operated at 0.4 day, 0.6 day and 1.2 days detentions. Aerobic conditions were maintained at these detention periods. In the second run, with an influent BOD of 100 mg/1, a detention time of 0.8 day led to anaerobic conditions in the laboratory pond. Aerobic conditions were maintained outdoors at0.8 day, 1.2 days and 2.4 days detentions. Best performance was attained at 2.4 days detention period. Generally, the BOD removal efficiency was higher in outdoor ponds. This was attributed to the more favorable environmental conditions such as greater light intensity and warmer temperature. These factors accelerated algal growth and bacterial metabolism and influenced the operational efficiency.
