Vedclass · Answer

(A) The $BOD$ (Biochemical Oxygen Demand) is a measure of the organic matter present in water. Higher organic content leads to higher $BOD$. $1$. Sewage $(S)$ typically has a moderate $BOD$. $2$. Paper mill effluent $(PE)$ contains cellulose and other organic wastes,resulting in a higher $BOD$ than domestic sewage. $3$. Sugar factory effluent $(SE)$ is rich in sugars,leading to a high $BOD$. $4$. Distillery effluent $(DE)$ is extremely rich in organic matter (molasses residues),resulting in the highest $BOD$ among these options. Therefore,the ascending order of $BOD$ is $S < PE < SE < DE$.

What is the ascending order of $BOD$ for the following: Sewage $(S)$,Paper mill effluent $(PE)$,Distillery effluent $(DE)$,and Sugar factory effluent $(SE)$?
