What does BOD stand for in wastewater treatment?

BOD stands for Biological Oxygen Demand, which is a key parameter used in wastewater treatment. It measures the amount of oxygen that microorganisms will consume while decomposing organic matter in the water. This measurement is vital for understanding the impact of wastewater on the environment; a high BOD indicates a higher level of organic pollution, which can deplete oxygen in receiving waters, harming aquatic life.

Biological Oxygen Demand is important for determining the efficiency of wastewater treatment processes. Treatment facilities aim to reduce BOD levels before effluent is released into the environment to ensure that the ecological balance in water bodies is maintained. Understanding BOD helps operators manage treatment processes more effectively, ensuring compliance with environmental regulations and protecting aquatic ecosystems.
