Controlling and preventing the growth of microorganisms in a cooling tower is extremely important and required to keep the system running at optimal levels. The presence of microorganisms will cause the system to breakdown and decreases the efficiency of the heat transfer. Typically oxidizing biocides such as chlorine and bromine have been used to treat cooling water. Unfortunately these chemicals are highly reactive with other chemicals and microbiological species found in the water. Chlorine dioxide however is very non-reactive to other compounds found in the water and retains biocidal efficacy. Likewise it is also a superior chemical for removing the biofilm, which leads to the most predominant problems that all cooling towers face.

Chlorine dioxide is used as a biocide in many industrial water treatment applications including cooling towers, process water and mill water. Its selective oxidative properties usually results in lower dosages of ClO2 while also achieving improved microbial performance.
