How it Works
Silver is attracted to cell wall of bacteriaweakening the cell wall

Electrostatic attraction between bacteria and AG+

16 times when silver is present
1. Clean water distribution system2. Attachment of bacteria (sec - min)
3. Growth and division of bacteria (hrs - days)
4. Expolymer production & Biofilm formation (hrs – days)
5. Attachment of other organisms to biofilm (days - months)

• Is perfectly safe in every respect at use concentration (100ppm hydrogen peroxide)
• Is perfectly safe in every respect at use concentration (100ppm hydrogen peroxide)
• Will not cause any wastage to any material it contacts
• Is perfectly safe in every respect at use concentration (100ppm hydrogen peroxide)
• Will not cause any wastage to any material it contacts
• It remains stable up to 95ºC – no breakdown in calorifiers
How do you use it?
How do you use it?• Chemical should be added to water in the water
storage tank following period of heavy use – after early morning baths in a nursing home
How do you use it?• Chemical should be added to water in the water
storage tank following period of heavy use – after early morning baths in a nursing home
• Calculate the volume of the system from tank volume X 1.3 (1.1 if no calorifier)

• Calculate the volume of the system from tank volume X 1.3 (1.1 if no calorifier)
• Add quantity of SafeSol3 indicated in Ready Reckoner
How do you use it?• Pull chemical to furthest hot and cold tap –
check level and then check presence of chemical at each outlet using SafeSol test strip
How do you use it?• Pull chemical to furthest hot and cold tap –
check level and then check presence of chemical at each outlet using SafeSol test strip
• When the correct level is observed at each tap, leave site. The disinfection will be complete 24 hours later assuming normal water use
Quantity to add for system volumeSystem Volume Volume of SafeSol 3
to obtain 100ppm hydrogen peroxide
Bottles you require to purchase
200 litres 500ml 1
300 litres 1 litre 1
500 litres 1.5 litres 2
1000 litres 3 litres 3
Quantity to add for system volume
• The hydrogen peroxide level should always be above 100ppm but below 125ppm to satisfy the DWI requirements - Test using test strips
Quantity to add for system volume
• The hydrogen peroxide level should always be above 100ppm but below 125ppm to satisfy the DWI requirements - Test using test strips
• If too high, run water out of the system via the outlets - if too low add more chemical
Over fussiness costs time!
