The term Biological Oxygen Demand (BOD) is used in relation to ______________________?
Correct answer: B. Industrial effluents
- A. Potable water
- B. Industrial effluents
- C. Distilled water
- D. Cooling water
Explanation
BOD measures the oxygen microorganisms require to biologically decompose organic matter in wastewater, so it is important for assessing industrial effluents. Potable and distilled water should have very low BOD.
