The BioSure Professional Water Tank Ozonator is your hassle-free solution for ensuring clean and hygienic potable water in your storage tank. Our WTO systems utilize advanced Electrolytic Ozone Technology to efficiently purify your water, swiftly eliminating germs and stubborn biofilm. Ozone, a safe and residue-free solution, naturally converts into oxygen, creating a clean water environment.

Water Quality Enhancement Benefits
Say goodbye to chlorine usage and harsh chemical treatments. Ozone provides powerful sanitization without the need for traditional chemicals.
Increases oxygen levels in water naturally, improving overall water quality and freshness without any additives.
Stops sediment and sludge accumulation in your tank, reducing maintenance frequency and extending tank life.
Enjoy clean water with no residual odor or taste. Ozone naturally converts to oxygen, leaving nothing behind.
Convenient Operation
Simple installation with no complex configuration required. Just plug in and start enjoying clean water immediately.
Minimal maintenance requirements with straightforward operation. No technical expertise needed for daily use.
Replace capsules quickly and easily when needed. Each capsule lasts up to 1000 operating hours for long-term use.
Can be integrated with timed power supply for automated operation. Set it and forget it for continuous water quality.

Sanitation and Safety
Utilizes dissolved O₃ (ozone) and OH (hydroxyl radicals) for powerful broad-spectrum sanitization that eliminates bacteria, viruses, and pathogens.
Effectively controls microbial growth and eliminates stubborn biofilm that conventional methods often miss. Keeps your tank truly clean.
Unlike some oxidation methods, the electrolytic process produces no harmful nitrogen oxides (NOx), ensuring safe water treatment.
Operates independently of air quality conditions. Reliable performance regardless of environmental factors or location.
Application Guidelines for Potable Water
CT Values are pivotal in calculating disinfectant dosage for drinking water treatment. Measured in mg-min/L, a CT of 1.6 is widely accepted as the minimum threshold for effective ozone disinfection in potable water.
| WTO-Mini Dosage Guidelines | ||
|---|---|---|
| Tank Size | Suggested Dosage | Estimated CT* |
| 100L | 0.3 hour | ≥ 3.0 |
| 200L | 0.5 hour | ≥ 3.0 |
| 500L | 1.0 hour | ≥ 2.4 |
| 1,000L | 1.5 hours | ≥ 1.8 |
| WTO Standard Dosage Guidelines | ||
|---|---|---|
| Tank Size | Suggested Dosage | Estimated CT* |
| 1,000L | 0.5 - 1.0 hour | 1.8 - 3.6 |
| 2,000L | 0.5 - 1.0 hour | 1.8 - 3.6 |
| 5,000L | 1.5 hours (by 2 units) | ≥ 2.2 |
| 10,000L | 2.5 hours (by 2 units) | ≥ 2.2 |
*CT Values are pivotal in calculating disinfectant dosage for drinking water treatment. They result from multiplying the disinfectant concentration (e.g., ozone) by the contact time with the water. Typically measured in mg-min/L, a CT of 1.6 is widely accepted as the minimum threshold for effective ozone disinfection in potable water.
