A water treatment plant is being designed to process 50,000 m3/d of water. Jar testing and pilot-plant analysis indicate that an alum dosage of 40 mg/L with flocculation at a Gt value of 4.0 × 10^4 produce optimal results at expected water temperature of 15 degrees. (?=1.139×10-3 N.sm2 (@ T=15 degrees). Determine:
1) The monthly alum requirement
2) The flocculation time, assuming G=30 s-1 3) The volume of the flocculation basin (V=Qt) 4) Power requirement
