Which of the following process is employed to gain sufficient head for the waste water?
Correct Answer: D — Pumping
Pumping facilities may be employed to gain sufficient head for the waste water to flow through the treatment works to the point of final disposal. Pumping is also generally required for recirculation of all or part of the flow around certain units within the plant. Pumping facilities are classified as influent, effluent, or recirculation stations and perform a critical function.
