  2. Which of the following is the first step in the wastewater treatment process?

    Answer: Primary treatment

    Primary treatment involves screening and sedimentation to remove large solids and some organic matter from wastewater.

  3. What is the main goal of secondary wastewater treatment?

    Answer: To reduce the biochemical oxygen demand (BOD) and suspended solids

    Secondary treatment uses biological processes to further degrade organic matter, reducing BOD and suspended solids in the wastewater.

  4. Which process is commonly used for nutrient removal in tertiary wastewater treatment?

    Answer: Biological nutrient removal (BNR)

    BNR processes, such as nitrification and denitrification, are used to remove nitrogen and phosphorus from wastewater during tertiary treatment.
