A water treatment plant is processing water at a flow rate of 1.5 m/s using three parallel treatment trains. The detention times for the rapid mix tank, flocculation basin, and rectangular sedimentation basin are 10 sec, 30 min and 60 min, respectively. The velocity gradients for the rapid mix and flocculation tanks are 900 s and 60:40:20 s1, respectively. The viscosity of water is 0.001 Pa-s. (a) Determine the size and power requirements for rapid mix tanks. (b) Determine the...

A new water treatment facility will be built to supply water to the town of Freemont. The town's population is currently 14,000 and the per capita water use is 100 gal per day. The new facility will be designed to account for increases in both per capita water use and population growth, and projections for water use will be determined for fifty years in the future. The population of the town of Freemont...
