The main purpose of tertiary treatment in a municipal wastewater plant is to:
Correct answer: C. Improve effluent quality beyond secondary treatment
- A. Remove coarse floating debris
- B. Provide preliminary grit removal
- C. Improve effluent quality beyond secondary treatment
- D. Transport sewage to the plant
Explanation
Tertiary treatment provides additional polishing after primary and secondary treatment, such as removing residual solids, nutrients or specific contaminants. Screens and grit chambers are preliminary units, while transport is the function of the sewer network.

About Environmental Engineering
Environmental engineering examines water supply, water quality, treatment processes, wastewater collection and treatment, solid waste management, air pollution and public health protection. It covers sedimentation, coagulation, filtration, disinfection, biological treatment and disposal methods, while distinguishing drinking-water treatment from sewage treatment and BOD from COD.
