You have been asked to provide a design for a rapid mix tank at a water treatment plant which has an average water temperature of 50°F. The tank is to have a detention time (ta = 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 and gallons) b. Find the reactor dimensions (i.e., Depth and Diameter, in feet) if the rapid mix tank is cylindrical with a depth 2x the basin diameter. Calculate the water power required (in HP) to achieve the desired mixing. d. If motors are available with an efficiency of 68%, what motor power is required (in HP)? с.

Aluminum (or Aluminum) is a silvery-white in color metal. The chemical symbol of aluminum is Al and it has an atomic number (Z) of 13 in the periodic table. The aluminum name for this metal is derived from the Latin word ‘alumen’, which means bitter salt…
