A Bangkok public pool: 2026, 18 swimmers developed swimmer's ear and skin infections; Pseudomonas aeruginosa found in the filter system. Pool closed 5 days for re-validation. Pseudomonas is opportunistic, dangerous in immunocompromised patients, surgical wounds, and antibiotic-resistant. Ozone kills Pseudomonas at 99.99% in 30-60 minutes. WHD is Thailand's only Hospital-Grade ozone service at 10,000 mg/h.
Pseudomonas aeruginosa is a gram-negative bacterium found in water, soil, plants, and hospital systems. Causes swimmer's ear, otitis externa, skin infections, and surgical wound infections.
In cancer, burn, surgical, and immunocompromised patients, may cause sepsis with high mortality. Resists multiple antibiotics — hard to treat.
Forms biofilm on inner pipe walls, pool surfaces, water tanks, HVAC. Tolerates low chlorine.
Pool chlorine at 1-3 ppm does not destroy Pseudomonas biofilm. Requires 20+ ppm shock dose or ozone. Ozone is the strongest oxidizer — destroys biofilm and reaches every cavity in HVAC.
Master Ozone Generator 10,000 mg/h kills Pseudomonas + biofilm at 99.99% in 30-60 minutes.
