Problem:
A clarifier designed for a flow of 9,000 m3/day has an area of 400 m2. What is the settling velocity (mm/s) of the particles that this basin is intended to remove? What diameter (mm) sand particles (?= 2,650 kg/m3) will be entirely removed? What diameter (mm) flocculated mud particles (?= 1,030 kg/m3) will be removed?
Note: Please explain comprehensively and give step by step solution.
