Q1/
Wastewater treatment plant use one circular primary clarifier to treat 10000
m/day of wastewater contain 210 mg/l of BOD and 260 mg/l of SS. the removal
efficiency in this clarifier is 35% for BOD and 60% for SS when the surface over
flow rate is 60m/m'.day and the detention time is 2hr , estimate:
1. The dimensions (diameter and depth) of this clarifier.
2. The mass of solids removed in the clarifier
3. The effluent concentration for BOD and SS.
4. Mass of solids going to the secondary clarifier
