A rectangular shaped sedimentation tank is to be built for a design flow of 600 m3/h. If the detention time, overflow rate and weir loading rate are 3 hours, 50 m3/m2.d, 100 m3/m.d, calculate the length, width and depth of the tank and the weir length. (assume length to width ratio of 3:1) (8 points)

You have been retained to design a wastewater treatment plant using a conventional activated sludge process for a town of 40,000 people. The industrial flow contribution to the sewer system is 300,000 gallons per day. Effluent discharge standards require effluent BOD5 and total suspended solids concentration of <10 mg/l. Assume the following design criteria are applicable: Domestic sewage flow = 100 gal/cap/day (including I/I) BOD loading = 0.18 lbs/cap/day TSS loading = 0.20 lbs/cap/day BOD removal in primary = 33%...

Design a completely mixed activated sludge process using three different design approaches (i.e. calculate the volume of the aeration basin). Base your design for the first approach on detention time, for the second one on BOD loading, and the third one on kinetics. The influent design flow rate to the activated sludge process is 10,000 m3 /day with a BOD5 concentration of 200mg/L. Completely mixed activated sludge processes typically have a detention time ranging from 3 to 6 hours and...
