Chlorine Dioxide Bello Zon® CDKc


“Chlorine-Free” Chlorine Dioxide (ClO2) Generation

With its Bello Zon® CDKc ProMinent is setting new safety standards in the production of chlorine dioxide using the chlorite-acid method. In the new process version the safety standard of dilute precursor chemicals is combined with the economy of concentrated chemicals, in that concentrated hydrochloric acid is pre-diluted in an intrinsically safe dilution station. Consequently the risk of inadvertently mixing concentrated chemicals within the system is excluded.

Thanks to the integrated dilution, the chemical consumption can be matched both to various acid concentrations and the local individual operating parameters and consequently be significantly reduced in comparison with existing systems, thus increasing economy.

Instead of the PVC hitherto used in the industry, PVDF is used for the chlorine dioxide reactor. This results in higher operating safety and improved purity of the generated chlorine dioxide.

The central system controller manages the precise production of the chlorine dioxide. Chlorine dioxide, chlorite, pH or redox potential sensors DULCOTEST® can be directly connected via the two mA inputs. This makes possible the online monitoring and documentation of the water parameters associated with the chlorine dioxide treatment. Using the integrated PID controller, the chlorine dioxide concentrations in the water can be adjusted automatically depending on the measurement. All status messages and measured values are documented in the integral data logger and visualized in the easy-to-understand color display via the screen recorder.
