Cooling Towers - The use of chlorine
dioxide in cooling
towers, loops and cooling systems greatly assists
in the control of Legionella bacteria, algae, planktonic
bacteria, biofilm and scale, helping to control the
presence of dangerous bacteria and maintain the efficiency
of heat exchanger surfaces, reservoir intakes, and ancillary
equipment.
Traditional oxidising agents such as chlorine and bromine
suffer from pH constraints and corrosion problems. Chlorine
dioxide is significantly more stable than other oxidising
biocides and is also compatible with most water treatment
chemistry.
Why is it Important to Control Biofilm in Such Systems?
Biofilm protects colonies of unwanted bacteria and
also 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.
Biofilm also creates an environment that promotes the
growth of anaerobic microorganisms, including Legionella
bacteria, which in turn increases microbiologically
induced corrosion (MIC) problems.
