Ozone is a strong disinfectant and an interesting alternative for the chemical biocides in cooling tower water treatment. During cooling tower water treatment, three main factors must be controlled
Through effective ozone treatment, all these aspects can be controlled collectively, without further addition of chemicals
Scaling is formed as a result of calcium and magnesium ion deposits on the units of a cooling system. This negatively influences heat transport leading to other complications within the system. A bio film can also be formed in the cooling water system, consequentially leading to clogging of microorganisms which increases scaling. Ozone treatment limits scaling. Ozone is a disinfectant that decomposes bio films and decreases chances of scale formation
Corrosion is mainly caused by microorganisms, which enhance corrosion forming conditions. A residual ozone concentration of 0.1 to 0.2 ppm is in most cases very effective in keeping the cooling tower and the cooling circuit clean by forming a corrosion preventing film on metals. Ozone reduces the corrosion rate of metals, including copper heat exchangers
Ozone Destroys all types of micro-organisms instantly as it is 3,125 times more germicidal than chlorine
Ozone is the most environmentally friendly oxidant that is effective in a wide PH range. It is produced on-site and requires no storage of dangerous chemicals. Ozone requires no additional disinfectants
