Which is the most widely used coagulant for the treatment of turbid water ?
Correct answer: A. Alum (aluminium sulphate)
- A. Alum (aluminium sulphate)
- B. Lime
- C. Ferric chloride
- D. Sodium aluminate
Explanation
Alum, or aluminium sulphate, is the most commonly used coagulant for turbid water because it neutralizes particle charges and forms flocs that settle readily. Ferric salts and lime are also used, but less commonly for routine turbidity removal.
