Chlorine Dioxide System Bello Zon CDKd

7.5 – 12,000 g/h chlorine dioxide. 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 safety concept protects people and the environment. The certified yield guarantees efficient chlorine dioxide production. Bello Zon CDKd can be easily and safely integrated into any water treatment process.

Chlorine Dioxide System Bello Zon CDKd: Treats Medium to Large Volumes of Water with Concentrated Chemicals.

In the chlorine dioxide system there is an intrinsically safe pre-dilution station for concentrated hydrochloric acid. The consumption of hydrochloric acid can therefore be automatically adapted on-site to the individual operating conditions by means of a patent-pending process.

The system control offers impressive and user-friendly menu navigation and ensures the precise production of chlorine dioxide. The chemicals are mixed perfectly in a reactor made of food-safe PVDF. You thereby benefit from maximum yield 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 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 and DULCONNEX
  • Monitoring of starting feed chemical tanks thanks to precise level indicators

* The metering figures relate to 5 or 2 bar back pressure and an ambient temperature of 20 °C. The minimum capacity/hour is based on the fact that when the system is operating at below 5 % of the nominal capacity, continuous metering is no longer possible due to the fact that the metering pumps then have a low pumping frequency. 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.
