Copper silver legionella
ATECA is market leader in copper-silver ionisation for legionella prevention.
How effective is copper-silver ionization? Copper-silver ionization can deactivate Legionella bacteria and other microorganisms in slow-running water and still water. Legionella bacteria are very susceptive to copper-silver ionization. Copper-silver ionization also takes care of bio film. Copper remains within the bio film, causing a residual effect.It appears that copper-silver ionization additon causes the number of Legionella bacteria to diminish. After a short period of time, however, the number of Legionella bacteria will rise again because they can also be found in the bio film. Copper that stays behind in the bio film takes care of these bacteria. When copper and silver ions are added to water constantly, the concentration of Legionella bacteria remains low.The deactivation rate of copper-silver ionization is lower than that of ozone or UV. A benefit of copper-silver ionization is that ions remain in the water for a long period of time. This causes long-term disinfection and protection from recomtamination. Copper and silver ions remain in the water untill they precipitate or absorb to bacteria or algae, and are removed from water by filtration after that.Copper-silver ionization affectively deactivates Legionella bacteria and bio film and it improves water quality. Copper-silver ionization has a larger residual effect than most other disinfectants. Copper and silver ions remain in the water for a long period of time. Because of its local affectivity, the effect is larger than that of UV. Copper-silver is effective throughout the entire water system, even in dead-end points and parts of the system that contain slow-running water. Copper-silver use affectivity does not depend on water temperature. When copper-silver is used, less maintenance to the water system is required. Copper-silver is non-corrosive; it causes less strain on the distribution system. Because of a decrease in the use of chemicals, the lids and pumps are not affected. Furthermore, shower heads, tanks and taps are not contaminated. When copper-silver ionization is applied, there are no transport and storage difficulties.Copper-silver affectivity depends on the pH value of the water. At a pH value of 9, only one tenth of all Legionella bacteria are removed. When dissolved solid concentrations are high, silver will precipitate. This means silver ions are no longer available for disinfection.Silver ions easily react with chlorines and nitrates that are present in the water, causing them to no longer be effective.Some species of microorganisms can become resistant to silver ions. They can remove metal from their systems or convert it to a less toxic product. These microorganisms can become resistant to copper-silver ionization.Copper silver legionella:Allthough it is suggested that Legionella bacteria can develop resistance to copper-silver ionization, this disinfectant still appears to be effective for Legionella deactivation.To affectively kill pathogenic microorganisms, copper and silver ions should be present in the entire water system. When the system is used little and the water flow is quite slow, or when there are dead-end points in the system, this can causes problems for disinfection.

This inspection determines the pH balance, conductivity, degree of hardness and chloride content.Analysis of the mains water quality prior to installation One month prior to the installation of the ICA-system, the water quality in the piping network is also analysed. ATECA selects a few tap points for this analysis based on a risk analysis. The analysis concerns the hot water temperature, TVC (22°/37°), copper and silver concentrations and legionella population.Monthly water analysis after installation It is the policy of ATECA to have monthly water analyses carried out during the first year after installation of the ICA-system. The same tap points are always used for these analyses, which provide a good overview of water quality. After the first year, the frequency of the analyses is reduced to once every two months.
