Grit removal in a waste water treatment plant :
Answer: D
The answer is All of the above.
Grit chambers in preliminary treatment let heavy inorganic particles such as sand, gravel and cinders settle, while the lighter organic solids pass on (C).
Removing this abrasive material protects pumps and other mechanical equipment from wear (A) and stops it from depositing in channels and pipes, where it could cause plugging (B; the paper prints 'pip'). It also keeps grit from building up in digesters and clarifiers. As all three statements describe grit removal, no single option is complete.
