The ultimate BOD value of waste is the amount of biodegradable organic matter presents in the sewage sample. At any temperature the amount of organic matter present does not change, so the ultimate BOD will remain same for any temperature.

°C increase in temperature.
b) decreases with temperature.
The BOD (biochemical oxygen demand) value of a waste refers to the amount of oxygen required by microorganisms to break down the organic matter in the waste. As temperature increases, the rate of microbial activity also increases, leading to a faster breakdown of organic matter and a lower BOD value. Conversely, at lower temperatures, the rate of microbial activity decreases, resulting in a higher BOD value. Therefore, the ultimate BOD value of a waste decreases with increasing temperature.
