UV and Ozonation Technology
Integrating advanced water purification technology such as UV and ozonation is crucial for ensuring a clean, safe, and healthy swimming environment. These systems provide efficient solutions for cutting down on chemicals, removing contaminants, and boosting water quality. Here’s a look at how UV and ozonation systems operate and their advantages.

- Step 1: Establish a Chemical Baseline. Before anything else, conduct a full water analysis. You must know your starting values for Total Organic Carbon (TOC), UVT at 254 nm, alkalinity, and iron/manganese levels. This data is non-negotiable and dictates all subsequent design parameters.
- Step 2: Engineer the Ozone Injection System. The goal is complete dissolution of ozone gas into the water. I insist on using a venturi injector followed by a static mixer and a contact tank. The crucial KPI here is the CT value (Concentration x Time). You must ensure sufficient contact time for the ozone to begin its work before it reaches the UV chamber.
- Step 3: Size the UV Reactor with AOP in Mind. Do not size the UV reactor for disinfection alone. You must select a medium-pressure UV lamp, as its polychromatic output is more effective at driving the AOP reaction. The dosage, measured in mJ/cm², must be calculated to both disinfect and catalyze the breakdown of the residual ozone from the previous step.
- Step 4: Integrate Real-Time Monitoring and Control. An AOP system cannot be "set and forget." You must install an Oxidation-Reduction Potential (ORP) sensor after the ozone contact tank and a UV intensity sensor inside the reactor. These sensors should feed back to a PLC that dynamically adjusts ozone output and UV power, maintaining peak performance while minimizing energy consumption.
- Step 5: Install an Ozone Off-Gas Destruct Unit. This is a critical safety and efficiency step. Any undissolved ozone must be safely converted back to oxygen. A thermal or catalytic destruct unit is mandatory for any professional installation.
