Watershape University

Ozone has been used for decades in advanced water treatment facilities from bottled drinking water to Shamu’s personal pool at Sea World. In the last 5 years it has started to infiltrate the pool and spa markets in various ways with multiple manufacturers offering products designed and sized for many applications. Ozone and ultraviolet sterilization will continue to grow in popularity as more builders understand it and the service professionals learn to service it. This two-day program is the first of its kind, offering expertise on everything from sizing and sales to installation, troubleshooting and routine maintenance.

Learning Outcomes

  • Compare and contrast ozone science and performance to other industry sanitizers.
  • Calculate fluid flow, ozone production, contact tank sizing, CT-values and other engineering parameters using guidance from standards and codes promulgated by the Model Aquatic Health Code (MAHC) and the EPA.
  • Describe ozone equipment components, disassembly, reassembly and routine maintenance to extend product life.
  • Explore facilities using ozone in residential and commercial applications to evaluate various installation configurations including bypass versus dedicated-system designs.


  • Duration: 12 hours
  • IACET CEUs: 1.2
  • All students who complete the course and evaluation form receive a Certificate of Completion documenting 1.2 IACET CEUs even if they do not continue with the Certified Watershape Ozone Specialist (CWOS) certification.
