![b. Find the DUB
10. A water treatment plant treats the water at the rate of 33 MGD. Average initial suspended
solids concentration is 21 mg/L. Coagulation reduces 95% of the suspended solids
concentration. (Average alum dosage = 18 mg/L). Determine the total dry weight of sludge
produced in Ibs/day.
Al2(SO4)3 14H₂O + 6 HCO3
2Al(OH)3(s) + 6CO2 +14H₂O +3S0²
11. The pH of the water is measured as 8.5 and the total concentrations of carbonate species is
found to be 0.00180M. Find the concentrations of H₂CO3, HCO3 and CO² by using
equations.
12. What is the pH of the solution containing 2.5 X 10 of OH- at 25°C?
13. The dissolved oxygen concentration in the fresh water sample was found to be 8.05 mg L
The solubility of oxygen in the sample was measured at 0.83 atm and 22 °C. Compare your
values from the table and report the percentage error. Note: Sample does not contain any salt](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2ad24375-0e35-46d0-ae73-58d7d895a57f%2Fb7612b4e-8a2a-46f9-b533-c6de0289ae98%2Fzr33w56_processed.jpeg&w=3840&q=75)
