Chemical Oxygen Demand Testing | EBS

Chemical oxygen demand, (,COD,) relies on chemical oxidation with chromic ,acid, (a strong oxidizer). Many organic compounds, including color bodies and fibers, which are not easily biodegradable, along with any inorganic chemicals will show up as ,chemical oxygen demand, but not biochemical oxygen demand (BOD). Some mills have found that filtered ,COD, samples give a […]
