Chlorine Dioxide Generators and Delivery Systems

Clearwater are specialists in the design, installation, operation and maintenance of Chlorine Dioxide Delivery solutions for all types of challenges, including:

  • Continuous mains water Treatment and Secondary Disinfection
  • Legionella Control Using Chlorine Dioxide
  • Bacterial and Pathogen Control Including
    • Biofilms
    • Cryptosporidium
    • Norovirus
    • E.Coli
    • Coliforms
    • Pseudomonas
  • Cold water distribution System Treatment and Disinfections
  • Cold Water Storage Tank Disinfection
  • Chilled Water Systems and Cooling Towers
  • Boreholes and Primary Open Water Treatment
  • Recycling and Grey Water Conditioning
  • Effluent Treatment
  • Odour Control
  • Reverse Osmosis feed water treatment

As well as the important Health and Safety aspect of Chlorine Dioxide Generation and Delivery we always consider the more 'traditional' water treatment aspects; to ensure maximum plant life, minimise unscheduled downtime and reduce energy costs - which means reduced financial outlay for our customers and 'business partners'.

Continuous Mains Water Treatment Using Chlorine Dioxide

National conditions of use of chlorine dioxide allow up to 0.5ppm of chlorine dioxide to be consumed. This means that it is possible to dose into drinking water systems, as well as down water services such as showers and other systems that are likely to generate aerosols. The use of chlorine dioxide as a control measure is described in ACOP:L8: Legionnaires Disease - The control of legionella bacteria in water systems; where it is suggested as a biocide treatment for the control of Legionella bacteria.

The 0.5mg/l limit includes the total concentration of chlorine dioxide, chlorite and chlorate. As chlorine dioxide is far more effective as a biocide than chlorite or chlorate, generation methods that generate purer chlorine dioxide solutions can be significantly more effective control measures than less pure methods. It is here that Clearwater catalytic technology comes into its own.

Chlorine Dioxide Generation

Clearwater are Technological leaders in Chlorine Dioxide Generation. Not only are we able to offer the most modern generation technologies, we can also provide chemicals and service to the vast majority of generators currently in the field.

Our own generation methods include:

  • Catalytic Generation, the purest and possibly safest generation method available
    • Industrial generators
    • Commercial generators
    • Low volume generators
    • Portable generators
    • Bespoke and custom generators
    • Two Pack and Stabilised Chlorine Dioxide Mixing Systems
    • Tablets and Powders

We utilise the best Chlorine Dioxide Monitors and Gas detection systems as part of our robust health and safety packages. These are all installed and serviced by our team of specially trained engineers, site service specialists and technical experts.
