Chlorine Dioxide System Bello Zon® CDVc
1 – 2,000 g/h chlorine dioxide. Max. flow at 0.2 ppm ClO2 metering is 10,000 m3/h
Chlorine dioxide system for monitoring and metering chlorine dioxide and diluted chemicals. Maximum output and safety due to special reactor concept. Bello Zon® CDVc can be easily and safely integrated into any water treatment process.
Bello Zon® CDVc is the convenient system for the treatment of average to large volumes of water.
Continuous water treatment using the chlorine dioxide system Bello Zon®CDVc can be simply and safely integrated into any process. The special reactor concept generates chlorine dioxide safely and simply with maximum output.
Food-compatible PVDF is used instead of PVC generally used in the industry. This results in improved operating safety and reliability and improved purity of the chlorine dioxide generated. The central system controller manages the precise production of the chlorine dioxide. All parameters relevant for water treatment are recorded and logged.
The stroke lengths of ProMinent® metering pumps are monitored online. This rules out hazardous operating statuses arising from incorrect pump stroke length adjustments.
The precise production of chlorine dioxide is managed by the central system control. Chlorine dioxide, chlorite, pH or ORP potential sensors DULCOTEST® are directly connected to the two mA inputs. The chlorine dioxide is monitored in the treated water and documented. The chlorine dioxide concentrations in the water can be adjusted automatically depending on the measurement by the integrated PID controller.
The integrated data logger documents all status messages and measured values, which the screen writer then visualises on the clear colour display.
The systems meet all the requirements of the DVGW specifications W 224 and W 624 with regard to construction and operation and are designed for operation with diluted chemicals Bello Zon® chlorite (7.5% NaClO2) and acid (9% HCl).

| * | The metering figures relate to 5 bar back pressure and an ambient temperature of 20 °C. The minimum capacity/per hour is based on the fact that when the system is operating at below 5% of the nominal power, continuous metering is no longer possible because of the correspondingly low pumping frequency of the metering pumps. When systems are not operating continuously, the reactor contents should be changed at least twice daily. The system should not, therefore, be operated below the stated minimum capacity/day. |
