The use of chlorine dioxide in cooling towers, loops and cooling systems greatly assists in the control of algae, planktonic bacteria, bio-film and scale, helping to maintain the efficiency of heat exchanger surfaces, reservoir intakes, and ancillary equipment. Traditional oxidizing agents such as chlorine and bromine suffer from pH constraints and corrosion problems.
Chlorine dioxide is significantly more stable than other oxidizing biocides and is also compatible with most water treatment chemistry. Chlorine dioxide controls algae, plank tonic and sessile bacteria, and bio-film.
Why is it important to control bio-film in such systems? Bio-film acts as an insulator causing deterioration in general heat transfer properties. It creates fouling and corrosion problems by accumulating scale in pipe work and equipment.
Bio-film also creates an environment that promotes the growth of anaerobic microorganisms which in turn increases microbiologically induced corrosion (MIC) problems. Using chlorine dioxide will lead to significant cost savings including water cost, corrosion problem, reduce maintenance cost and Improved system performance.
