Chlorine Dioxide - The Ideal Biocide

For most of the history of use of chlorine dioxide, it has been applied dissolved in water, as a liquid. Great effort had been used to keep the gas entrained within the water during use. Over the past ten or twelve years, however, the unique properties of gas phase chlorine dioxide has been recognized. Research using chlorine dioxide in its natural gaseous state, as a fumigant, rather than as a rinse, spray or fog, has produced an exciting new frontier in ClO2 applications.   Gas phase chlorine dioxide has the following benefits:

  • It is effective against a wide variety of bacteria, yeasts, viruses, fungi, protozoa, spores, molds, mildews and other microbes. It is particularly effective at killing Giardia, Cryptosporidium and Legionella.
  • It exhibits rapid kill of target organisms, often in seconds.
  • It specifically targets bonds that are only present in harmful or odorous molecules or species. Hardly any of it is consumed by reactions with harmless substances. This means that it is highly effective as a biocide at very low concentrations.
  • Chlorine dioxide is biodegradable.  No residue and no trace of the gas is left after treatment.

Most importantly, because a gas will expand from an area of high concentration to an area of low concentration, fumigation applications are ideal for disinfection of a wide array of areas when the elimination of bio-contaminates is critical. Using a fumigant rather than a fog or spray is the only application technique that assures total coverage of the active ingredient into every crack and crevice in the treatment space.
