Vedclass · Answer

(A) $BOD$ (Biochemical Oxygen Demand) refers to the amount of dissolved oxygen that would be consumed if all the organic matter in one liter of water were oxidized by bacteria.Greater $BOD$ indicates a higher concentration of organic pollutants in the water,which requires more oxygen for decomposition.Therefore,a higher $BOD$ value directly correlates to a higher polluting potential of the waste water.Thus,the correct statement is that the greater the $BOD$ of waste water,the more is its polluting potential.

Which one of the following statements regarding $BOD$ is true?
