Chlorine Dioxide System Bello Zon® CDKd

8 – 12,000 g/h chlorine dioxide. The maximum volume of water that can be treated with metering of 0.2 ppm ClO2, depending on the size of the system: 60,000 m3/h

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

Product description

Chlorine dioxide system Bello Zon® CDKd treats medium to large volumes of water with concentrated chemicals.

There is an intrinsically safe pre-dilution station for concentrated hydrochloric acid integrated in this chlorine dioxide Chlorine dioxide is an exceptionally reactive gas, which is not stored due to its instability ... more in the glossary system. The consumption of hydrochloric acid can therefore be automatically adapted on site to the individual operating conditions by means of a patented process. Savings of up to 20 %.

The system control offers impressive and user-friendly menu navigation and ensures the precise production of chlorine dioxide Chlorine dioxide is an exceptionally reactive gas, which is not stored due to its instability ... more in the glossary. The chemicals are mixed perfectly in a reactor made of food-safe PVDF. You thereby benefit from maximum output with the lowest possible consumption of chemicals and maximum operating safety. The requirements set by the Industry 4.0 standards of tomorrow are met thanks to communication via popular bus systems, a web server A web server is a software application executed by the DULCOMARIN® II. more in the glossary and our DULCOnneX Platform.

The construction and operating mode of the system also complies with all requirements of DVGW specifications W 224 and W 624 and the system is intended for operation with concentrated chemicals Bello Zon® chlorite (24.5% NaClO2) and acid (25 – 37% 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

  • Cost savings through optimised acid consumption
  • 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
  • Consumption levels can be planned, enhanced availability and economical operation thanks to verification of chlorine dioxide metering and system output
  • Simple compliance with documentation obligations and evidence of correct operation using automatically generated reports and alarms
  • Remote maintenance thanks to DULCOnneX in a safe environment, yet still on-site. 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.
