Description

​The Millennium III™​ Chlorine Dioxide Generator is a safe and reliable solution for disinfection by-product compliance, CxT disinfection credits, iron & 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 service ensures compliance and eliminates down-time.

Read how Chlorine dioxide is an effective solution for disinfection byproduct (DBP) control of TTHM's and HAA5's. This is evidenced in the "", a thesis authored by Erica LaBerge and published by the University of Central Florida. This study utilized an Evoqua chlorine dioxide generator and found that chlorine dioxide minimized DBP formation relative to alternative pre-oxidants.

Features

Configurations

​The Millennium III™ Chlorine Dioxide generators are available in the following configurations, utilizing either 2-chemical or *3-chemical reaction chemistries:

  • Manual
  • Batch
  • Automatic
*3-chemical systems can be designed to accommodate 12.5% sodium hypochlorite or 0.8% on-site electrolytic-generated bleach. For more information on electrolytic-bleach generators, please see our OSEC® Hypochlorite Generation Systems.

Features

  • State-of-the-art control valves specifically designed for low flow control of precursor chemicals
  • Flow controls include PID loop for sodium chlorite
  • Touch screen interface allows for maximum performance, ease in set up, parameter changes and troubleshooting
  • Real time generator effluent analysis using an in-line (full flow) chlorine dioxide analyzer allows self-tuning and performance display

Applications

  • Primary and secondary disinfection for drinking water treatment
  • Pre-treatment for oxidation and removal of Iron & Manganese
  • Control of slime, algae, bacteria, viruses and protozoa, including Giardia, Cryptosporidium and Legionella
  • THM / THAA control (DBP reduction) without the formation of bromate 
  • Taste and odor control
  • Biofilm & Nitrification control
  • Mollusk control
  • Others
