Cooling Towers

Cooling Tower ozonation – an environmentally friendly alternative that saves water and eliminates the use of hazardous chemicals.

Keeping your cooling towers and heat exchangers free from biological growth, corrosion and scaling are vital for the operation of air conditioning or industrial cooling systems. Yet, the use of chemicals to treat the water in cooling towers is becoming increasingly regulated and restricted. It is not uncommon that when running at high load a cooling tower can discharge 10,000 or more litres of water per day. To make matters worse, the discharged water (or blowdown) is a non-reusable, hazardous trade waste because of the chemical additives.

Combine these issues with the increasing presence of the Legionnaires bacterium in cooling tower water and it is apparent why cooling tower operators are concerned about maintaining clean and hygienic cooling tower water in a reliable, cost-effective and environmentally friendly manner.

Now, saving water and reducing your reliance on chemicals while improving the functional performance of your cooling system has never been easier: ozonate the water.

Using a method developed by NASA in the USA for their own cooling towers, Ozone1 can now provide complete, turnkey cooling tower ozonation systems, a safe and cost-effective alternative to toxic and expensive chemical treatments. Ozone is created on-site and injected into your cooling tower water; your current chemical dosing system will be disconnected and no longer used. Ozone is a powerful and highly effective biocide, yet decomposes quickly into simple oxygen, thereby leaving no harmful residue. Should appropriate plumbing be available, blowdown can be reused, for example, to water gardens. Please contact Ozone 1 for relevant technical white papers.

Numerous case studies attest to the superior biological control properties of ozonating cooling tower water (versus using chemicals), which in turn reduces corrosion and scaling. Importantly, the cycles of concentration can be raised, usually by a factor of 200-300%, thereby saving thousands of litres of water per day.
