SCIENCE

The efficacy of chlorine dioxide as an aggressive oxidizing agent capable of destroying a wide range of compounds, including microorganisms and sulfur compounds, is well documented. CDG Environmental has focused its efforts on making this difficult to handle molecule available to users through a simple production device and as a pure dilute solution.

Analytics

The analytical chemistry of chlorine dioxide, especially in solution, is complicated by chlorine dioxide’s volatility, by its sensitivity to light and instability over time, and by interference from related redox species. Various analytical methods are in use, or have been proposed, with varying degrees of success.

Chemistry

Chlorine dioxide is a relatively small, volatile and highly energetic molecule. Chlorine dioxide is never transported as a compressed gas because of its instability; rather, it is typically generated as needed, at the point of use.

Microbial Kill

Chlorine dioxide is an extremely effective disinfectant, which rapidly inactivates bacteria, viruses parasites such as Giardia and to some extent, even the highly resistant encysted parasite Cryptosporidium. Chlorine dioxide’s combination of power and selectivity enable it to penetrate biofilms and destroy the resident microorganisms.

Legionella Treatment

Legionella and other bacteria thrive in biofilm which is impervious to most biocides. Chlorine dioxide has been shown to be an effective biocide for the destruction of the Legionella bacteria.
