1) A drinking water treatment plant uses a cubic rapid mix, rectangular flocculation basin, and rectangular sedimentation basin to treat 10.0 mgd of water. Size the volume for each basin using the characteristic detention time and flow through velocity requirements. What is the rapid mix volume for Dt = 30 sec? What is the floc. basin volume for Dt = 30 min? What is the floc. basin cross-sectional area for a velocity = 10.0 ft/min? What is the sed. basin volume for Dt = 4 hours? What is sed. basin cross-sectional area for a velocity = 0.5 ft/m?

You have been asked to provide a design for a rapid mix tank at a water treatme nt plant which has an average water temperature of 50F. The tank is to have a detention time (td= HRT) of 1.5 seconds, a mixing intensity (G) of 2,000/second, and treat a flow (Q) of 10 mgd. a. Identify the volume of reactor required (in ft^3 and gallons) b. Find the reactor dimensions (i.e., Depth and Diameter, in feet) if the rapid mix...

A rectangular horizontal-flow sedimentation basin in a conventional water treatment plant has been designed to treat a flow of 50,000 m3 /day. It has a length = 80 m, width = 20 m, and depth = 3.6 m. For this problem, assume temperature = 20 °C (density of water = 103 kg/m3 and viscosity = 10-3 kg/m·s) and laminar flow. a. What is the hydraulic detention time? Does this meet the typical criteria for this type of sedimentation basin? b....

The old plant grit removal process, that is used to treat the average flow of 15 MGD consists of horizontal flow grit chamber that have a volume of 15,000 gallons. To reduce the footprint of the process, the new plant will use a Vortex type grit chamber that is capable of achieving the same grit removal performance in a fraction of the reactor volume. Remember that the flow to the new plant is 10 MGD . 11. What is the...
