2018/11/1 · How to Reduce Chemical Oxygen Demand (COD) in Wastewater Written by AOS Treatment Solutions on November 1, 2018 Closely related to Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) is another important water quality parameter that industrial and municipal authorities should be familiar with to determine the best wastewater treatment methods for their needs.

Similarly, Chemical Oxygen Demand (COD), is the demand of oxygen required to reduce dichromate (Cr 2 O 72 -, Cr in 6+ oxidation state) to Cr 3 +. The COD test is more robust than BOD because not all organic matter is readily oxidized by bacteria. Additionally, other chemicals, and inorganic substances in the water can be oxidized by dichromate.

Hach New Zealand - Chemical Oxygen Demand (COD 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.

16mm Hach vials for vials for Chemical Oxygen Demand ( COD ) determination. Results displayed as O2 mg/l. Please note a reactor is required for sample digestion. The tube tests are in high-quality glass and the reagent tubes are shipped in special packaging to protect them during transport. All COD tests are available in a box of 25 tubes.
