Chlorine dioxide generation

Powerful treatment without transporting generated chlorine dioxide

Chlorine dioxide is a powerful oxidising agent and biocide. Because of its chemistry and properties, it is generally produced at or near the point of use. Enaqua configures the generation chemistry, controls and dosing package around the site requirement.

  • Broad-spectrum control of bacteria, fungi, algae, viruses and protozoa
  • On-site generation close to the point of use
  • Two-chemical systems for batch and inline configurations
  • Concentrated or dilute precursor options matched to the application

System configurations

One platform, three practical arrangements

Batch chlorine dioxide generation using sodium chlorite and hydrochloric acid

Batch generation

Produces a 1,500–2,000 mg/L chlorine dioxide solution in a tank for dosing to multiple nearby points with different residuals or injection rates.

Inline bypass chlorine dioxide generation configuration

Inline bypass

Suited to single treatment applications and higher water flows, with concentrated or dilute two-chemical options.

Direct inline chlorine dioxide generation configuration

Direct inline

Typically uses dilute precursor chemistry for single treatment applications and lower water flow rates.

Control and assurance

Built for safe, visible operation

Safety by design

Submerged reactors, chemical low-level switches, flow monitoring and motive-water interlocks protect the process and operators.

Intuitive control

PLC automation and a colour HMI provide detailed alarms, process control, totalisers and run-time tracking.

Connected operation

An IoT edge gateway supports remote alarms, trending, reporting, configuration and web-based system management.

Engineered for your site

Complete systems, not isolated equipment

Systems are backboard mounted as standard, with frames, chemical storage, bunding, dosing packages and full installations available to suit the project.
