Chlorine Dioxide System Bello Zon® CDVd

2 – 2,000 g/h of chlorine dioxide. Maximum volume of water that can be treated with metering of 0.2 ppm ClO2, depending on the size of the system: 50 - 10,000 m3/h

Chlorine dioxide system for the metering of chlorine dioxide with diluted chemicals. The certified output guarantees efficient chlorine dioxide production. The proven three-stage safety concept protects people and the environment. Bello Zon® CDVd can be easily and safely integrated into any water treatment process.

Food-compatible PVDF is used instead of the PVC generally used in the industry. You benefit from maximum output with the lowest possible consumption of chemicals and maximum operating safety. Communication via popular bus systems, via a web server A web server is a software application executed by the DULCOMARIN® II. more in the glossary and our DULCOnneX Platform fulfils all the requirements set by the Industry 4.0 standards of tomorrow.

The system meets all the requirements of the DVGW specifications W 224 and W 624 with regard to construction and operation and is intended for operation with diluted chemicals Bello Zon® chlorite (7.5% NaClO2) and acid (9% HCl). The liquid levels of the starting chemicals can either be displayed and monitored by external liquid level sensors or by adaptive liquid level monitoring for which a patent has been applied.

Your benefits

  • Maximum operating safety and purity of the CIO2 produced by PVDF reactors and three-stage safety concept
  • Communication interfaces via bus systems, web server or DULCOnneX
  • System does not stop due to empty starting feed chemical tanks, thanks to precise level indicators
  • Verification of the chlorine dioxide metering and system output: For consumption levels which can be planned and enhanced system availability
  • Automatically generated reports and alarms: For simplified compliance with documentation obligations and to demonstrate correct operation
  • Remote monitoring in potentially dangerous environments: At a safe distance, but still on-site - DULCOnneX. For more information: https://dulconnex.prominent.com/welcome.html

    *The metering figures relate to 5 or 2 bar back pressure and an ambient temperature of 20 °C. The minimum capacity/per hour is based on the fact that when the plant is operating at below 5% of the nominal power, continuous metering is no longer possible due to the then low pumping frequency of the metering pumps. The reactor contents should be changed at least twice daily with systems that do not work continuously. Therefore do not operate the system below the stated minimum capacity/day.
