A chlorination process is to be used to disinfect a wastewater treatment plant effluent. The plant treats 1.8MGD (million gallon per day). The water entering this unit has about 4500mg/L of coliforms, and the effluent target is 0.1 mg/L of coliforms. The rate of disinfection can be described by dC/dt=-kC where C equals the concentration of coliforms. A laboratory study determined that the k=0.75min-1. If a plug flow reactor is used, what is the required detention time and tank volume to meet the effluent criteria? Show all work.
