Vedclass · Answer

(A) $1$. $BOD$ (Biochemical Oxygen Demand) refers to the amount of oxygen that would be consumed if all the organic matter in one liter of water were oxidized by bacteria.$2$. $A$ higher $BOD$ indicates a higher amount of organic matter,meaning the water is more polluted. Conversely,a low $BOD$ indicates less organic matter.$3$. Therefore,the statement 'If the $BOD$ of a water sample is low,it contains a high amount of organic matter' is incorrect.$4$. Dissolved oxygen is inversely proportional to $BOD$; thus,high dissolved oxygen implies low $BOD$.$5$. Wastewater treatment involves primary (physical) and secondary (biological) treatment.$6$. During biological treatment,aerobic microbes grow into flocs (masses of bacteria associated with fungal filaments).
