Guide to Ozone Cooling Towers

This guide provides an overview of how ozone technology can be applied to cooling tower water treatment to improve water quality, reduce chemical dependency, and minimize water waste. The publication explains the principles of ozone injection, contact, and filtration while outlining ozone’s effectiveness in controlling bacteria, algae, organic contaminants, scale formation, and corrosion. It also discusses the operational and environmental benefits of ozone-treated cooling systems, including reduced blowdown requirements, lower maintenance costs, improved heat transfer performance, and enhanced sustainability. The guide serves as a practical introduction to ozone-based cooling tower treatment and the key considerations for successful system design, operation, and monitoring.
