Chlorine Dioxide System Bello Zon CDVd

2.5 – 2,000 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: 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.

Product description

Chlorine dioxide system Bello Zon CDVd is for the treatment of medium to large volumes of water with diluted chemicals.

The system control offers impressive and intuitive menu guidance 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 special reactor concept generates chlorine dioxide Chlorine dioxide is an exceptionally reactive gas, which is not stored due to its instability ... more in the glossary safely and simply. Food-compatible PVDF is used instead of the PVC generally used in the industry. You benefit from maximum yield with the lowest possible consumption of chemicals and maximum operating safety. Communication via conventional 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 thanks to PVDF reactors and three-stage safety concept
Communication interfaces via bus systems, DULCONNEX
System does not stop due to empty starting feed chemical tanks thanks to precise level indicators and measuring via radar sensors
Verification of the chlorine dioxide metering and system output: For consumption levels which can be planned and enhanced system availability
Configurable alarms and automatically generated reports: For simplified compliance with documentation obligations and to demonstrate correct operation
Remote monitoring of systems in potentially dangerous environments.

Field of application

Municipal drinking water and waste water treatment
Industrial process and cooling water
Disinfection in the food and beverage industry, above all with inlet water treatment

* 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.
