COD Testing Advantages. COD is most suitable for rapid and frequent monitoring of treatment plant efficiency and water quality. This method is more accurate than BOD (with a 5-10% relative standard deviation) and it offers a relatively short analysis time (2-hour digestion time), compared to the 5-day BOD test.

Nov 01, 2018 · COD value is usually expressed in milligrams per liter of water (mg/L). The Significance of Chemical Oxygen Demand. High chemical oxygen demand in water indicates greater levels of oxidizable organic matter and consequently, a lower amount of Dissolved Oxygen (DO). Critical DO depletion due to organic contamination can kill off aquatic life forms.

COD that can be measured using a 50-ml sample and 25-ml 0.25 N di chromate is 1,000 mg/1. A sample containing 10 g/1 chloride (equivalent to about 50-percent seawater) has a COD due to chloride of 2,300 mg/1. This restricts the sample volume to less than 20 ml and makes the measurement of COD's due to organic matter of 200
