Ozone Treatment for Cooling Towers

COURSE NO: M02-002
Ozone Treatment for Cooling Towers
Course Highlights

This online engineering PDH course describes the basics about ozone treatment of cooling towers as a "new technology". Cost benefits of using ozone in treatment of cooling tower water, application considerations, maintenance issues, utility initiatives, performance of cooling tower and laboratory versus case study perspectives are discussed.


The form of oxygen known as ozone has been recognized for nearly a century for its powerful ability to disinfect water.  Cooling tower water must be treated to limit the growth of mineral and microbial deposits that can reduce the heat transfer efficiency of the cooling tower. The use of ozone to treat water in cooling towers is a relatively new practice that is increasing in popularity, and it has good potential for use in commercial building systems.


This 2 PDH online course is applicable to mechanical engineers, design and construction personnel, technical staff and facility personnel who are interested in gaining a better understanding of ozone treatment for cooling towers.
