8. A water treatment plant with a surface water intake source is being designed for a municipality that has a water demand of 18 million gallons per day (MGD). It has been determined that the maximum daily summertime water temperature is 20oC, and the minimum daily wintertime water temperature is 5oC. It has been determined that the design of the disinfection system must achieve 2.5-log credit for Cryptosporidium removal or inactivation. Ozone will be used as the disinfectant with a concentration of 0.4 mg/L. If the contact basin is designed with three separate tanks in parallel, what volume should each tank be? In formulating your answer, use the Ct table specified in LT2ESWTR (provided below). Assume that the contact basins will behave as ideal plug flow reactors.

A municipal water treatment plant is designed to produce 20 million gallons per day (MGD) of potable water. The plant treats surface water using coagulation followed by sedimentation, filtration, and chlorination. Although the water is hard, it is not presently softened. The water is coagulated using a 30 mg/L dosage of alum (aluminum sulfate, Al2(SO4)3•14.3H2O, MW = 600). This chemical reacts in water to form Al(OH)3 as follows: Al2(SO4)3 + 6HCO3- → 2Al(OH)3(s) + 3SO4-2 + 6CO2 How many mg/L...
