Chlorine Dioxide Generation Systems

Chlorine Dioxide is a powerful disinfectant and oxidizing agent. It has been used for many years in water treatment systems for the elimination of chlorophenols , the oxidation of inorganic compounds such as iron and manganese, and in the control of taste, odor and color. It is recognized by the EPA as a primary disinfectant and is effective against viruses, bacteria and protozoa, including the cysts of Giardia and the oocysts of Cryptosporidium. Chlorine dioxide does not react with ammonia to form less-active chloramines. It will not form trihalomethanes (THM’s) or other chlorinated organic compounds, nor will it react with the many impurities that normally consume chlorine.

Millennium III™ Chlorine Dioxide System

Chlorine dioxide has proved economical and effective when treating waters high in ammonia or organic nitrogen and in the destruction of phenol-based taste and odor causing compounds. Essentially, this is because chlorine dioxide is not affected by pH, thus it is a cost effective means of water treatment when the pH is high.

Siemens Water Technologies offers a broad range of chlorine dioxide generators, specialized chemical feed systems, and an extensive line of water treatment chemicals.

Applications

Primary disinfectant for water treatment
Pre-treatment for oxidation and removal of iron and manganese
Post-treatment for destruction of phenol and chlorophenol compounds that produce odors and affect effect taste
Control of contaminant bacteria and organics in situations where significant ammonia is present
Control of slime, bacteria and viruses in applications where chlorine is unacceptable

Chlorine Dioxide Generation Case Study

Treating Water With Chlorine Dioxide Reduces THMs, Improves Taste for Arkansas Water Treatment Plant

The 1.8 MGD Greenwood Water Treatment Plant was built in 1964 and upgraded in 1992. The facility provides drinking water to a population of more than 7,000 and, like many small towns, Greenwood has faced major decisions about how to remain in compliance with the Safe Drinking Water Act. Because its water supply is provided by a very shallow lake (less than 10-feet deep), sourcewater quality can vary widely. “We often get a lot of organics, and this had brought about high trihalomethanes (THMs) in our finished water when we prechlorinated,” says Greenwood Water Superintendent, Mack Cochran. THMs were running more than 115 mg/l and as high as 175 mg/l.
