1、 SZ-COD COD online analyzer product overview:
Chemical Oxygen Demand (COD) refers to the mass concentration of oxygen consumed by strong oxidants under certain conditions when oxidizing organic and inorganic reducing substances in water samples. COD is also an important indicator reflecting the degree of pollution of water bodies by organic and inorganic reducing substances.
This analyzer is capable of long-term automatic continuous operation according to on-site settings, and is widely applicable to industrial pollution source discharge wastewater, industrial process wastewater, industrial wastewater treatment plant wastewater, municipal wastewater treatment plant wastewater, and other occasions. According to the complexity of the on-site testing conditions, corresponding preprocessing systems can be selected to ensure the reliability of the testing process, accurate testing results, and fully meet the on-site requirements of different occasions.
24-hour real-time monitoring
2、 SZ-COD COD online analyzer productPrinciple:
The water sample, digestion solution, liusuan silver solution (liusuan silver as a catalyst can effectively oxidize linear fatty compounds), and concentrated liusuan mixture are heated to 175 ℃. After the organic matter in the solution is oxidized by dichromate ions, the color will change. The analyzer detects this color change and converts it into COD value output. The amount of dichromate ions consumed is equivalent to the amount of oxidizable organic matter, which is the COD value.
