The percentage of suspended solid waste in raw water is removed by coagulation is?
Correct answer: C. 80
- A. 60
- B. 70
- C. 80
- D. 90
Explanation
In many coagulation processes, achieving an 80% removal of suspended solids from raw water is indeed feasible. Coagulation, along with subsequent processes like flocculation and sedimentation, can effectively remove a significant portion of suspended solids, leading to clearer water. Therefore, option (c) "80" is correct in this context.(Environmental chemistry,Components of Environment)
