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?

A conventional, rectangular flocculation basin is 38 ft. wide, 90 ft. long and 16 ft. deep. The flow through the basin is 24 mgd and the water horsepower input by the reel type paddles is 15 hp. The dynamic viscosity of water is 2.73 E -5 lb/sec/ft2 at 50 degrees Fahrenheit. The flocculation basin in above is followed by four sedimentation basins which operate in parallel.   Each basin is 30 ft. wide, 240 ft. long and has an effective settling...

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....

A water treatment plant has five identical rapid sand filters. Each is square in plan and has a capacity of 1 MGD. The application rate is to be 4 gal/min-ft2 and the total wetted depth is 10 ft. Each filter will be backwashed every day for 5 min. The rate of rise of the backwash water is 2 ft/min. A) What should be the cross-section dimensions of each filter? B) What percentage of the plant's filtered water will be used...

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...
