Boilers and cooling towers share two major water related problems: deposits and corrosion. As steam is generated by a boiler or water evaporating from a cooling tower, dissolved minerals are left behind, increasing the concentration of these minerals. Additional minerals are introduced via the water added to makeup the water lost to steam/evaporation. Eventually, the minerals reach a level (or cycle) of concentration that will cause either loss of efficiency due to scale or damage from corrosion. This level can be determined by the Ryznar or Langlier indices and correlated to a conductivity or TDS range. Most people recognize problems associated with corrosion. Effects from scale deposits, however, are equally important. For example, as little as 1/8` of scale can reduce the efficiency of a boiler by 18% or a cooling tower heat exchanger by 40%!

Low maintenance and reliability are key requirements for analyzers in potable water plants. Cost of ownership is another big issue.

Chlorine dioxide (ClO2) is well suited for upstream gas production during oil and gas operations, as well as other oil and gas water applications. Chlorine dioxide is highly effective and more sustainable than other oxidizing or non-oxidizing biocide options.

CleanOxide Chlorine Dioxide can safely be used for washing fruit and vegetables, seafood, meat, mushrooms and many other foodstuffs. CleanOxide Chlorine Dioxide destroys bacteria including potentially harmful pathogens such as E.coli, as well as controlling fungi and fungal spores ensuring reduced risk for the consumer and increased shelf life for the produce. Residual chlorine dioxide left on the produce degrades rapidly leaving no harmful residues.
