Chemical Oxygen Demand (COD)   What is Chemical Oxygen Demand (COD)? Chemical oxygen demand (COD) is the amount of dissolved oxygen that must be present in water to oxidize chemical organic materials, like

Ascorbic Acid Atrazine Bacteria- see Microbiology BOD (Biochemical Oxygen Demand) Chloramine Chlorine Chlorine Dioxide COD (Chemical Oxygen Demand) Copper Detergents - see Surfactants Dissolved Oxygen Fluoride

be used to model treatment plant processes to increase the efficiency and effectiveness of wastewater treatment. COD versus BOD Like BOD, chemical oxygen demand (COD) can be used to estimate the amount of organic loading in a water sample. COD describes the amount of oxygen required to chemically breakdown the pollutants, while BOD indicates the

. What is the relationship between BOD, COD and TOC? Biochemical oxygen demand (BOD) can be estimated from chemical oxygen demand (COD) measurements, if a correlation is established. This requires historical data
