Question:
Which is the effective pH range for aluminum sulfate as coagulant in water treatment?
Which is the effective pH range for aluminum sulfate as coagulant in water treatment?
Show Hint
Always ensure the pH is in the effective range for coagulants to function optimally. The proper pH improves the coagulation process significantly.
Updated On: May 3, 2025
- 8.5 and above
- 3.5 to 6.5 and above 8.5
- 4 to 7 and above 9
- 6.5 to 8.0
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The effective pH range for aluminum sulfate as a coagulant in water treatment is 8.5 and above. At pH values below 8.5, aluminum sulfate may not be effective, and the coagulation process may not proceed efficiently.
