Millennium III™ Chlorine Dioxide Generators

Combining technology and expertise to deliver safe, consistent, high-purity chlorine dioxide

​The Millennium III™​ Chlorine Dioxide Generator is the safest, most reliable solution for disinfection by-product compliance, CxT disinfection credits, iron and manganese removal, and taste and odor control. Concentrated chemical precursors are vacuum fed to safely control reactions, maximizing chlorine dioxide yield efficiency at 95 percent and minimizing by-product formation.  Fail-safe mechanisms prevent chemical feed due to loss of motive water or vacuum, ensuring safe operation.

Millennium III generators comply with NSF 61 standards for drinking water applications and are easy to use and maintain. Evoqua’s best in class local service ensures compliance and eliminates down-time.

 Features

​The Millennium III Series Chlorine Dioxide generators are available in the following configurations:

  • Manual
  • Batch
  • Automatic

 Key Benefits

  • ​Disinfection by-product (DBP) Rule II compliance.
  • The cost-effective, safe generation of chlorine dioxide is a primary design consideration. Generation under vacuum is used to minimize and control the reactions and concentrations.
  • Efficiency / yield is maximized by reaction of chemical precursors in their concentrated form. These reaction conditions favor the immediate formation of chlorine dioxide, thereby minimizing by-product formation found in other types of generators.
  • Direct flow path of motive water and chemical precursors provide for minimal pressure losses and improved flexibility.
  • Unique injector design incorporates vacuum based vapor phase reaction chemistry to improve overall performance and safety.
  • NSF 61 certified for drinking water applications.
