Thermo Scientific Orion 3106 COD analyser

The Thermo Scientific Orion 3106 COD analyser is the latest addition to the portfolio of Orion products serving the wastewater industry. Chemical oxygen demand (COD) analysis is used to detect levels of organic pollutants in water; early identification of these contaminants can indicate an issue in the treatment process of wastewater.

The analyser combines a digestion step with colorimetric analysis to measure the concentration of organic compounds that can affect water quality. Particularly high levels of COD may require additional treatment processes. The presence of high COD levels during the disinfection process will lead to additional hypochlorite dosing. This results in the formation of chloramines, which, if present in high levels, can be carcinogenic.

The analyser is designed to reduce ongoing operating costs due to its low maintenance and reagent consumption. Furthermore, by controlling the treatment process, users can reduce disinfection costs. The intuitive user interface simplifies navigation for an enhanced operator experience.
