Chlo­rine dioxide gener­a­tors

Flexible Effective

Chlorine dioxide is highly effective against all types of germs

The BWT UK range of chlorine dioxide generators have been designed and developed to offer a flexible effective means of water disinfection to a diverse array of business and commercial premises.

Chlorine dioxide is a very effective disinfectant and will attack and remove a biofilm. BWT Chlorine dioxide generators are used to accurately mix two chemicals together in a controlled environment, the product of which is then carefully used to dose the water delivery system. Suitable for flow rates up to 200m3 with the advantage of no taste or odours. The dosing can be controlled manually or modulated automatically.

Typical systems consist of an electronic dosing pump, flow sensors and a state of the art electronic control panel.

Typical Applications

  • Hotels and restaurants
  • Schools, colleges and universities
  • Hospitals and laboratories
  • Food and manufacturing industries
  • Electronics industry
  • Sports and leisure facilities
  • Paper industries

Easily installed

High operational reliability and lower maintenance costs

Chlo­rine dioxide is often used to combat legionella in build­ings, for disin­fecting cooling water systems, and process water. The BWT compact chlo­rine dioxide gener­ator system used in the UK is robust, compact and user friendly ensuring oper­a­tional reli­a­bility, lower main­te­nance costs and ease of use.

This intel­li­gently controlled method for producing chlo­rine dioxide is designed to operate effi­ciently whilst using less chem­i­cals and can save up to 67 % of hydrochloric acid over other types of systems with a compa­rable capacity. In compar­ison with thermal disin­fec­tion, up to 90 % of the oper­ating costs can be saved. While the low chlo­rine dioxide concen­tra­tion of approx. 2 g/l (2000 ppm), means the produced solu­tion can be stored for several days reducing waste and at the same time is safe to handle. The whole system can be installed easily in most loca­tions and can in some cases even be taken into oper­a­tion without inter­rupting the build­ings water supply. This can repre­sent a deci­sive cost factor where water is in use 24 hours a day. Oper­a­tional acces­sories are also avail­able to facil­i­tate assembly and start up.

The flex­i­bility of the system also means measuring devices for chlo­rine dioxide, Ph and Redox can easily be added to the control unit which is supplied with suit­able connec­tions as stan­dard.

Chlorine dioxide generator

BWT’s Plug and Play chlo­rine dioxide gener­a­tors are easy and simple to use and provides very effec­tive disin­fec­tion to ensure safe water for building like hotels, hospi­tals, and resi­den­tial build­ings. The chlo­rine dioxide solu­tion produced is and is added to the drinking water supply as required. They are avail­able in four capac­i­ties, from 5 - 60 g/h of chlo­rine dioxide This capacity is suffi­cient to treat up to 150 m3 of drinking water per hour.
