A PFR is not meeting effluent requirements so baffles are going to be added to the tank to increase contact time. The tank is 12 ft deep, 40 ft wide, and 120 ft long. The engineer is going to add long baffles to the tank. The baffles will be 90% of the tank length. If the current HRT is 0.5 d, and the influent concentration is 9 mg/L with an effluent limit of 1.5 mg/L, how many baffles need to be added? Assume k=1.98/day
