A method of purifying impure water to provide drinking water using an apparatus, the method comprising the steps of providing a microfiltration unit (14, 20), a reverse osmosis unit (70) and a CIP (clean-in-place) tank (100) containing retentate interconnected to permit backflushing the microfiltration filter (20) with retentate and continued or interrupted operation of the reverse osmosis unit (70) by directing retentate thereto.
L'invention concerne un procédé de purification d'eau impure permettant de produire de l'eau potable en utilisant un appareil. Ce procédé consiste à utiliser une unité de microfiltration (14, 20), une unité à osmose inverse (70) et un réservoir (100) de purification en circuit fermé (CIP) renfermant le concentrat. Ces trois modules sont interconnectés pour permettre la circulation inverse de concentrat dans le filtre de microfiltration (20), ainsi que la poursuite ou l'interruption du fonctionnement de l'unité à osmose inverse (70) en y dirigeant le concentrat.
