Chlorine Dioxide for Cooling Water Disinfection

Chlorine Dioxide is a disinfectant, that, due to it's mutliple advantages, replaces Chlorine more and more often in cooling water applications. Its disinfection force is stronger and independent of the water’s pH. Due to its specific chemistry, no chlorinated by-products can be developed,  AOX-values are decreased by more than 90 % compared to chlorine. The much  longer half-life affords better depot action in treated water. Because almost no microbiological resistances are developed, it can be metered continuously. Contrary to chlorine, chlorine dioxide is able to remove biofilm in pipe systems and tanks to abolish growth of Legionella.

With the help of DULCOTEST® - sensors, a measurement-dependent metering of chlorine dioxide is possible.

Advantages

• high efficacy even at low concentrations at any pH value, thus less corrosion
• high depot action due to long half-life
• almost no microbiological resistances
• no contamination with Legionella
• no chlorinated by-products, strongly reduced AOX-values in waste water  
• online-measurement possible

ProMinent Bello Zon® - plants together with corresponding measurement and control technologies DULCOMETER®  and/or DULCOTEST®  afford optimal tuned systems for disinfection of cooling water circulation.
