Ozone solution helps swim school handle increased bather load
Sue Howlett runs a thriving swim school in the Queensland suburb of Loganholme, just south of Brisbane. Howlett’s unique instructional technique and purpose-built centre have seen it become one of the preferred swim schools in the area, averaging up to 1200 bathers per week in its 130,000 L pool and 300 bathers per week in the smaller 24,000 L pool.
As the business continued to grow, Howlett found that her sanitation system wasn’t keeping up with the increased demand, so she sought a solution that would improve the water quality and give her peace of mind.
Her research led her to fellow Queensland company Ozone1, which installed a primary and secondary disinfection system for the school’s two pools.
Howlett said that the new systems resulted in the water quality being the best it has ever been at the school, continuing to impress patrons and staff alike. Water clarity improved immediately, and combined chlorine levels now sit firmly at 0.3 ppm and below — well below the legal safe limit of 1.0 ppm combined chlorine. Her staff and clients have commented that they no longer experience chlorine odours and eye/skin complaints.
For the primary disinfection, Ozone1 installed its Hydroguard 302 Blue I DPD1 and DPD3 smart controller to ensure consistent levels of primary sanitation (free chlorine and pH).
Ozone1’s Proprietary System Calculation was used for the CO2, along with the company’s Advanced Oxidation Process, Ozone + UV (AOP) as a secondary disinfection system. This was designed and built especially to combat the school’s issues with combined chlorine and, in particular, monochloramine.
The Hydroguard Blue I controllers use a colorimetric DPD method to determine the free chlorine and total chlorine measurements, as opposed to relying on traditional ORP or free chlorine sensors, resulting in extremely consistent sanitation (chlorine and pH) levels.
The Blue I system conducts a DPD1 and DPD3 test every 10 minutes, and each and every test can be uploaded via remote monitoring to the cloud where it is stored for two years, serving as valuable evidence to satisfy a possible complaint. The remote monitoring also allows access to view the school’s water quality at all times and if setpoints aren’t met, alerts are sent to the appropriate personnel via text message or email.
“I have been in the Swim School industry for 33 years and in my current location for the past 20 years. During this time I have struggled, like most operators, to keep my combined chlorine levels within range given my bather load,” said Howlett.
“After installing an Ozone1 system through Brauer Industries this has all changed. The system does what is promised.
“My combined chlorine levels are now well under the required levels. My staff now have a very comfortable environment to work in. I now have peace of mind knowing that my water is of a very high standard.
“Thank you to David Brauer and his team for their very professional service before, during and after installation.”
