Requirements on the quality of water above all depend on the application. Depending on the purpose of use and application of water, the raw water is to be treated correspondingly. Chlorine dioxide has long been known as disinfectant in drinking water treatment and is now also increasingly used for oxidation and disinfection of polluted waters such as industrial, process, and cooling water. The chlorine concentrations prescribed by EU directives can be met by using the corresponding measuring and control technology. In order to avoid random sampling, monitoring can be implemented reliably and comfortably with amperometric sensors by ProMinent (Germany). ProMinent have launched their new dirt-tolerant chlorine dioxide sensor CDR 1 mA.
The design of the sensor type CDR 1-mA was modified such that it can be used especially in polluted industrial, process and waste water as well as in cooling water applications or surfactant-polluted waters. This is ensured by a dirt-tolerant, non-porous diaphragm protect the sensitive measuring electrodes against the sample medium. The diaphragm protect because it is permeable for chlorine dioxide but not for interfering dissolved and undissolved water components. The sensors provides a temperature-compensated 4...20 mA signal for measurements in a temperature range of 1 to 55'C. Precise measurements can be realised in a pH range of 1 to 10.0.
