Copper Silver Ionisation Support

Copper Silver Ionisation Support

What is Copper Silver Ionisation and how does it work?

Studies indicate that legionella bacteria is becoming more resilient to control measures such as temperature control, superheat and flush, UV, filtration, chlorine and chlorine dioxide. Copper Silver ionisation units can be effective in deactivating legionella bacteria and biofilms in domestic hot and cold water systems.

Copper Silver ionisation is a dispersive process that introduces stable, positively charged copper and silver ions into the water system. The ions bond electrostatically with negative sites on bacterial cell walls and denature proteins. This means that ionisation disperses and destroys biofilms and slimes that can harbour Legionella bacteria, which can be inaccessible to other disinfectants.

Control of a water system can take in excess of 30 to 45 days and flow cells should be cleaned periodically to maintain the system. We have seen some great results from this solution and clients have benefited from the energy savings, a reduction in their carbon footprint as well as reducing their scald risk and enhancing their legionella compliance.

Validation & Support Service

We provide an independent system validation service. Site visits may include any or all of the following, subject to your circumstances:

  • Check the voltage and current readings on the meters in the control unit.
  • Check erosion and calcification levels of electrodes and clean them (if necessary).
  • Check level of ions in the water.
  • Copper test at various points throughout the site.
  • Take water samples for Legionella and Total Viable Count (TVC).
  • Check for specific bacteria including E.coli and pseudomonas.
  • Provide trending results and regular reports on each system.

Benefits of Copper – Silver Ionisation in comparison with other methods of water treatment

Energy consumption – as Silver and Copper levels become stabilised and effective, temperatures in the system can be lowered leading to lower heating costs, therefore commonly where temperature was the primary control for legionella, elevated hot water temperatures are no longer required.

Savings in time and maintenance of the system – less time is required for cleaning and disinfecting the system, biofilm is attacked and removed in water systems, reducing nutrient sources such as sediment, scale, corrosion and both organic and inorganic matter. Less maintenance is required on tanks, calorifiers, taps, TMVs and shower heads.

Capital Investment – taking away temperature control removes the requirement for Thermostatic Mixing Valves (TMVs). Installation of TMVs resolve the scald risk; however these water blenders are proven to proliferate Legionella bacteria. Copper Silver ionisation is a solution to this. Although building regulations now state that the use of TMVs are required for all public areas with vulnerable and young people, with Copper Silver ionisation, Organisations can save thousands on their energy bills and when stabilised, TMVs can be removed.

Non corrosive – Copper Silver does not corrode metals in the distribution system such as copper, galvanised steel and aluminium.

Energy savings – reduction in hot water temperatures means energy savings and budget compliance
