Copper silver ionisation
ATECA is market leader in copper silver ionisation for legionella prevention.
Copper-silver ionization is brought about by electrolysis. An electric current is created through copper-silver, causing positively charged copper and silver ions to form.Copper-silver ionization brings us back to basic chemistry: an ion; an electrically charged atom, has a positive charge when it gives up an electron and a negative charge when it takes up an electron. A positively charged ion in called a kation and a negatively charged ion is calles an anion. During ionization, atoms turn into kations or anions. When copper-silver ionization is applied, positively charged copper (Cu+ and Cu2+) and silver (Ag+) ions are formed.The electrodes are placed close together. The water that is disinfected flows past the electrodes. An electric current is created, causing the outer atoms of the electrodes to lose an electron and become positively charged. The larger part of the ions flows away through the water, before reaching the opposite electrode. Generally the amount of silver ions at a copper ion rate of 0,15 to 0,40 ppm lies between 5 and 50 ppb.The ion concentration is determined by the water flow. The number of ions that is released increases, when electric charges are higher.When copper ions (Cu+) dissolve in water, they are oxidized immediately to form Cu2+ ions. Copper can be found in the water in free form. It is commonly bond to water particles. Copper (Cu+) ions are unstable in water, unless a stabilizing ligand is present.What are the applications of copper-silver ionization?Copper-silver ionization is suitable for a large number of applications. It became of interest when NASA used copper-silver ionization for drinking water prodcution aboard Apollo space ships in 1960. The ion generator that was used, was the size of a matchbox.Because of copper-silver ionization, drinking water could be produced safely in space without the use of chlorine.

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.
