Question
A water treatment plant treats of water per day. As a part of the treatment process, discrete particles are required to be settled in a clarifier. A column test indicates that an overflow rate of per hour would produce the desired removal of particles through settling in the clarifier having a depth of . The volume of the required clarifier, (in , round off to 1 decimal place) would be _______
Correct answer
495 to 505
Solution
1.Calculate the flow rate () in :
2.Determine the required surface area () using the overflow rate ():
3.Calculate the volume () of the clarifier using the given depth ():
Rounding to one decimal place, the volume is .Continue learning with Success Tracker
