Abstract

L'invention concerne un système de traitement de l'eau, destiné à éliminer des métaux et des gaz nocifs de puits et d'eaux de fond afin de rendre l'eau potable. Le système utilise des microbulles d'oxygène qui restent en suspension dans l'eau à une concentration supérieure à 100 % de la concentration saturée calculée à une température et une pression particulières. Ces microbulles oxydent les substances indésirables dans l'eau, lesdites substances comprenant du fer, du manganèse, de l'arsenic, de l'antimoine, du chrome, de l'aluminium, des composés de soufre réduits, des résidus de pesticides, des métabolites de médicaments et/ou des bactéries. Les microbulles sont produites par électrolyse ou par barbotage au travers d'un micro-orifice. L'invention concerne également un système de commande pour le système électrolytique.
