CVE 360 - Environmental Engineering Homework 2 AIUS AMERICA INTERNATIONA UNIVERSIT Problem 1 A wastewater treatment plant is required to disinfect its effluent before releasing treated wastewater into a neighboring stream. An inflow concentration of a certain infectious germ in the wastewater is 25,000 mg/L. A concentration of 2,000 mg/L is the highest concentration that can be released. It is suggested that the disinfection process employ a pipe that carries the effluent. The length of the pipe is 1000 m and the reaction rate constant is 0.1 min¹. Assume that the pipe behaves as a steady-state plug-flow system. Determine a) The residence time of this system (min) b) The speed of flow in this system (m/min) c) If the pipe has a diameter of 250 mm, determine the flow rate in the pipe (m³/hr) Cin 25000 mg/L L = 1000 m pipe = Cout 2000 mg/L k = 0.1 min 1
