Title
(EN) WATER PURIFICATION APPARATUS
(FR) APPAREIL DE PURIFICATION D'EAU
Abstract
(EN)
Apparatus which is adapted to purify water by the introduction of metal ions into the water. A chamber (16) is provided which houses two electrodes (E1 & E2) which are made of metals whose ions are known to have water-purification properties. Water to be purified is passed through the chamber, whereupon a controlled concentration of purifying ions are passed into the water. The metal ions preferably include silver and/or copper to control respectively bacteria and algae. Furthermore, in order to minimise adverse electrolytic effects it has been found advantageous to reverse the polarity of the potential difference across the electrodes at regular intervals.

Appareil destiné à purifier de l'eau par l'introduction d'ions métal dans cette dernière. Une chambre contient deux électrodes composées de métaux dont les ions possèdent des propriétés de purification d'eau connues. L'eau à purifier circule au travers de la chambre, traversée à son tour par une concentration régulée d'ions de purification. Les ions métal comprennent de préférence de l'argent et/ou du cuivre agissant respectivement sur les bactéries et sur les algues. En outre, afin de réduire au minimum les effets négatifs électrolytiques, l'on a remarqué qu'il est avantageux d'inverser la polarité de la différence de potentiel aux bornes des électrodes à des intervalles réguliers.
