The sewage water is treated until the BOD is reduced. The BOD test measures the rate of uptake of oxygen by micro-organisms in a sample of water and thus, BOD is indirectly a measure of the organic matter present in the water. The greater the BOD of waste-water more is its polluting potential.

BOD (Biochemical Oxygen Demand) measures the amount of dissolved oxygen that microorganisms require to break down organic matter in water. It is an important parameter in assessing the quality of water, particularly in terms of its pollution levels.
Statement a: Sewage water is treated until the BOD is reduced.
This statement is true. Sewage water undergoes treatment processes to reduce its BOD levels. This is done to ensure that the water is safe for discharge into the environment, as high BOD levels can deplete oxygen levels in water bodies, leading to adverse effects on aquatic life.
Statement b: BOD is a measure of organic matter present in the water.
This statement is true. BOD is a measure of the amount of organic matter, such as decaying plant and animal material, present in water. High levels of organic matter indicate a higher BOD, which can lead to oxygen depletion and subsequent degradation of water quality.
Statement c: Greater the BOD, lesser is the polluting potential of water.
This statement is not true. In fact, the opposite is true. A higher BOD indicates a greater amount of organic matter present in the water, which implies a higher pollution potential. High BOD levels can result in oxygen depletion, leading to the death of aquatic organisms and degradation of the ecosystem.
Statement d: BOD measures the rate of uptake of oxygen.
This statement is true. BOD measures the amount of oxygen that microorganisms utilize while breaking down organic matter in water. It provides an indication of the rate at which oxygen is consumed during the decomposition process.
Overall, statement c is not true because a higher BOD indicates a greater pollution potential, not a lesser one.
