About Ozone Generating Systems

March 22nd, 2012

We thought you might like to read a concise but thorough overview about ozone generating systems.  So here’s a link to our friends at the Association of Pool & Spa Professionals, who published an Information Bulletin on Ozone Generating Systems in their Recreational Water Quality section.  You can download a brief PDF at that link.  For more information about ozone generating systems, visit our aquatics Ozone Sanitation Systems page, and browse through that website, or visit our residential pool site for information specifically geared to private pools.

Full disclosure:  DEL’s VP Beth Hamil contributed to this article.  That’s partly how we know it’s right.

What’s In the Bulletin

The Bulletin begins with a concise statement about pool and spa ozone systems that is worth quoting:

Ozone generating systems are electromechanical devices that generate and dissolve ozone gas into swimming pool or spa water. They provide antimicrobial oxidation for supplemental sanitation, oxidation of organic and inorganic contaminants, chlorine byproduct reduction and algaecide activity. This Information Bulletin examines the properties and the application of these devices.

Ozone systems are engineered for specific applications, and must be installed according to the manufacturer’s specifications.

All pool ozone systems consist of two basic components:  the ozone generator and the control system.  In commercial pools, the control system can be quite complex, including an ozone degas/destruct component and a built in ORP monitor/controller to manage oxidation potential.  Most residential pool systems control the ozone with the automatic vacuum-driven injection method combined with regular, frequent testing of the water for Free Available Chlorine and proper pH balance.  However, DEL Ozone does manufacture the Mixing Degas Vessel for larger residential pool systems to ensure the destruction of potential ozone off-gas.

Ozone destroys microbial organisms and other oxidizable contaminants on contact. Since these interactions occur in the pool water return line, with only very small residuals of ozone reaching the pool water body, the ozone system must be used in conjunction with an EPA registered sanitizer.  Most commonly, this residual sanitizer is chlorine, and chlorine is specified as the primary sanitizer for commercial pools under NSF/ANSI Standard 50.

DEL Systems Comply

The APSP description certainly fits DEL Ozone spa and pool systems. DEL pioneered the development of the first NSF-listed ozone system for commercial pools and spas in 1985, and continues to develop cutting edge systems known for effectiveness and reliability. Residential pool and spa systems by DEL share the engineering expertise and quality of the larger commercial systems.

DEL ozone generating systems provide the foundation for clean, healthy water in all types of pools and spas.
