Dechlorinated secondary effluent is placed in a storage basin until needed for reuse. The initial DO is 2.5mg/L, estimate the time required for the DO to reach 12.5mg/L due to surface reaeration, assuming the water in the storage basin is circulated and not stagnant. Assume KL= 0.04 m/h,Cs=10.09mg/L. The surface area of the storage basin is 600 m2 and depth is 8 m
