Biological Oxygen Demand (BOD)

Biological Oxygen Demand (BOD) is a crucial parameter used to measure the amount of oxygen required by microorganisms to decompose organic matter in water. It serves as an indicator of the organic pollution level in aquatic environments, reflecting the overall health and quality of water bodies. High BOD levels signify a significant presence of biodegradable organic materials, which can lead to oxygen depletion when microorganisms metabolize them. This depletion of dissolved oxygen can harm aquatic life and disrupt ecosystem balance.

Monitoring BOD levels is essential for assessing the effectiveness of wastewater treatment processes and ensuring compliance with environmental regulations. By managing and reducing BOD levels, water utilities can improve water quality, protect ecosystems, and support sustainable water management practices.
