ProMinent Bello Zon - Model CDVd -Chlorine Dioxide System

SHARE
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 starting chemicals. The certified yield guarantees efficient chlorine dioxide production. Bello Zon CDVd can be easily and safely integrated into any water treatment process.

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

The chlorine dioxide system CDVd is very user-friendly. The system control stands out due to it`s intuitive menu guidance and ensures the precise production of chlorine dioxide. The special reactor concept generates chlorine dioxide safely and simply. Chemically resistant PVDF is used instead of the PVC generally used within the industry. You benefit from maximum output with the lowest possible consumption of chemicals combined with the maximum operating safety. Communication via popular bus systems, via web server 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.

  • 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.
  • Municipal potable water and sewage treatment
  • Industrial process and cooling water
  • Disinfection in the food and beverage industry, above all with inlet water treatment
