Product Overview

COD is an important indicator to reflect the extent of water pollution ,which is polluted by the organism and inorganic reducing substances.

COD means under certain conditions, mass concentration of oxygen consumption, when use strong oxidizer, make organism and inorganic reducing substances oxidation. This analyzer can automatic continuous work for long-term in an unattended manner. And it is widely used in industrial pollution discharge wastewater, industrial process wastewater, industrial wastewater treatment plants, municipal wastewater treatment plants and so on. Depending on the complexity at the scene, for ensure reliable and accurate testing, can choose different pre-treatment system.


Product Principle

Water sample, potassium dichromate digestion solution, silver sulfate solution( Silver sulfate added as a catalyst can oxidize straight-chain aliphatic compounds more effectively), the sulfuric acid mixed and heated to 175℃. The color of the organics in the dichromate ions oxide solution will change. The analyzer detects the change of color, converts and outputs the COD value. The consumption of dichromate ions is equivalent to the consumption of oxidizable organic, that is COD.
