Cooling Tower Water Treatment
Chlorine dioxide provides a safe and cost-effective approach to cooling tower water treatment. While there are other oxidation chemistries available to use in heavy industrial water treatment (e.g. bleach, bromine or chlorine), none offer the combination of performance, safety, shelf-life, environmental and cost benefits like ClO2.
Better Microbiological Control
It is not an exaggeration to say that at least 80% of all cooling water problems relate to poor microbiological control, especially for hydrocarbon processing industries, like refining, petrochemical and ammonia. Microbial growth results in serious problems for these industries, including loss of heat transfer in heat exchangers, a collapse of cooling tower fill, equipment corrosion and more.
Chlorine dioxide is an ideal solution for microbiological control because it:
The biocidal properties of chlorine dioxide are uniquely suited to control Legionella bacteria in industrial cooling water systems. Unlike other disinfection chemistries, chlorine dioxide has a history of effectively eliminating biofilms that protect colonies of Legionella bacteria from disinfectants. ClO2 is proven to be highly effective at penetrating and eliminating biofilms that develop inside cooling systems. Competitive disinfectants require “hyper” dosage treatment levels to achieve effective Legionella kill. The selective nature of the ClO2 allows the chemistry to be fed at very low dosages to effectively eliminate the Legionella bacteria versus alternative disinfection programs. ClO2 is effective against viruses, bacteria, fungi, cysts, protozoa, Cryptosporidium, Giardia, amoebae and algae over wide temperature and pH ranges. Additionally, as a weaker oxidizer, ClO2 disinfection minimizes the formation of THM’s, carcinogens, and other harmful disinfection byproducts.
Chlorine dioxide’s selective reactivity results in favorable cost-effective economics compared to alternative oxidizing biocides, especially when the system is heavily contaminated.
