PureLine <br />Properties <br />Although chlorine dioxide (C102) contains a chlorine atom, its chemistry and properties make it more <br />similar to oxygen that chlorine -making it an effective and environmentally safe biocide ideal for <br />disinfecting vital water supplies to exacting standards. <br />Chlorine dioxide is an oxidizing biocide that kills microorganisms by disrupting nutrients across the cell <br />rather than disrupting the metabolic process. While non -oxidizing biocides also kill microorganisms, they <br />can only kill them when the microorganisms are active. Since microorganisms spend most of their time in <br />a dormant state, non -oxidizing biocides must be used at much higher concentrations and more frequently <br />to effectively kill microbial pollutants. In addition, microorganisms become resistant to non -oxidizing <br />biocides over time. Chlorine dioxide is an especially effective disinfectant because bacteria can not <br />develop a resistance to it. <br />Ozone and chlorine are very reactive and will react with most organic compounds. As a result, they must <br />be used in much larger doses to maintain a residual effect sufficient to kill microorganisms. But their <br />greatest drawback is that they produce dangerous disinfection by-products (DBPs) which are <br />unacceptable according to new standards established by the Environmental Protection Agency. In <br />contrast, C102 is far less reactive. Regardless of its concentration or contact time, chlorine dioxide reacts <br />immediately with the cell walls of microorganisms. <br />Chlorine dioxide is soluble as a true gas. The C102 molecule remains a true gas in solution -making it more <br />energetic and able to reach all points in a system. Because it is a true gas and soluble in virtually anything, <br />it can penetrate bacterial slime layers-biofilm. <br />Finally, chlorine dioxide and its primary by -products -chlorite and chlorate-all break down to sodium <br />chloride. This, along with failure to form toxic and carcinogenic chlorination by-products and produce a <br />build-up of toxic organic or inorganic by-products like bromates, makes chlorine dioxide the most eco- <br />friendly biocide that can be used. <br />Uses <br />A growing number of industries are relying on the superior disinfection and environmentally -friendly <br />properties of chlorine dioxide. Chlorine dioxide is quickly becoming the preferred bleaching agent in the <br />pulp and paper industry because it minimizes the environmental impact of the bleaching process. C102 is <br />also used to not only disinfect municipal and drinking water supplies, but also control the water's taste, <br />odor and color. In the food industry, chlorine dioxide disinfects water used to sanitize equipment and <br />preparation surfaces, wash fruits and vegetables, and prevent salmonella and e-coli from contaminating <br />meat and poultry. In commercial and institutional applications, C102 is used to prevent the spread of <br />legionella in hotels, hospitals and universities. Industrially, chlorine dioxide is an effective membrane <br />treatment, as well as a biocide for cooling and wastewater. It is used in the production of ethanol, <br />microelectronics, nitrogen and ammonia.
