What is a BOD-COD Online Analyzer and Why is It Essential?

What is BOD?
BOD, or Biological Oxygen Demand, measures the amount of oxygen required by microorganisms to decompose organic matter in water. This process, known as biological oxidation, is a natural way for water bodies to recycle and purify contaminants. Higher BOD values typically indicate a more polluted water body, as more oxygen is needed to break down the organic waste.
What is COD?
COD, or Chemical Oxygen Demand, quantifies the oxygen needed to oxidize organic compounds using chemical reagents. Unlike BOD, which relies on biological activity, COD is a chemical process, making it less affected by biological factors and more influenced by the presence of organic compounds that can be chemically oxidized.
The Relationship Between BOD and COD:
While BOD is influenced by biological processes, COD reflects the presence and type of organic matter in the water. Both parameters are interconnected, with BOD often being a subset of COD. This relationship underscores the importance of monitoring both parameters for a comprehensive understanding of water quality.
