| Abstract: | This paper was prepared to provide guidelines for effective ozone use in cooling tower systems based on known scientific actions of ozone and practical cooling system operation. It does not attempt to explain the unknown or unpredictable actions attributed to ozone. Guidelines for ozone use in cooling tower systems usually can be predictable, depending upon the specific industry or site conditions found. Ozone is not a panacea as a stand–alone treatment in most cases, but can be under the right conditions. Applicability of ozone depends upon specific criteria that must be evaluated prior to its consideration or use. If ozone is to be tested, then it is critical to have adequate monitoring tools in place to evaluate its performance, rapidly, before system damage may occur. Ozone has a place today in cooling tower system protection, and likely a greater consideration and use when a better understanding of its mechanisms of action is developed. |
