1. Introducing: The Best Disinfectant for Legionella Control! Silver Catalysed Stabilised Hydrogen Peroxide

4. Huwa-San TR50 How does it work ? Hydrogen peroxide stabilised around silver Silver “radiation” 1. The Silver Effect The silver weakens the outer defenses of the micro-organism

5. Huwa-San TR50 2. The hydrogen peroxide effect Increase in kinetic energy due to presence of micro-organism Hydrogen peroxide pull away and head toward micro-organism

6. Huwa-San TR50 The combined effect The presence of the Silver has weakened outer defense mechanism. This in combination with the increased energy of the hydrogen peroxide leads to: Micro-organism oxidised DNA destroyed

7. Huwa-San TR50 The residual H 2 O O 2 After the reaction with the micro-organism we are left with: They disappear into the environment They loose their kinetic energy… … and return to await their next target…

8. Water Microbiology – Biofilm

9. Water microbiology 1. Base layer forms 2. Surface layer develops in columns 3. Polysaccharides secreted by bacteria

10. 4. Protozoa come and graze on biofilm Water microbiology

11. 5. Legionella penetrate protozoa …and live in it multiplying until protozoa bursts Water microbiology An amoeba (red) pulling a Legionella bacterium (green) into the amoeba cell.

13. Huwa-San TR50 The components (%) of an efficient disinfectant clean

18. A Good Legionella Biocide Needs to demonstrate efficacy as: Huwa-San TR50 Better 1. Fast Legionella killer TNO Testing 2. Amoebicide Rennes Testing 3. Biofilm removal chemical VITO /PIDPA Tests
