The number of coliform bacteria is reduced from an initial concentration of 2,000,000 per 100 ml to 400 per 100 ml in a long, narrow chlorination tank under a steady wastewater flow with a hydraulic detention time of 30 min. Assuming second-order kinetics and ideal plug flow, calculate the reaction rate constant. What would be the hydraulic detention time needed to produce the same effluent quality if you assumed perfectly mixed flow in the chlorination tank
