Abstract[English]
A reverse osmosis system includes a pressure vessel comprising first and second ports. Membrane modules, disposed in the pressure vessel, permeate water through membranes disposed in the modules and block permeation of dissolved solids from concentrate flowing between the first and second ports. A high pressure pump includes an inlet and an outlet. A circulation pump is configured to circulate the concentrate between the first and second ports. The circulation pump includes an inlet and an outlet. A valved circulation apparatus is configured to select between a forward flow mode and a discharge mode of the system. In the forward flow mode, the circulation pump inlet is connected to the second port and the circulation pump outlet is connected to the first port. In the discharge mode, the circulation pump inlet is connected to the high pressure pump inlet and the circulation pump outlet is connected to the first port.[French]
Un système d'osmose inverse comprend un récipient sous pression présentant des premier et second orifices. Des modules de membrane, disposés dans le récipient sous pression, permettent l’infiltration d'eau à travers des membranes disposées dans les modules et bloquent l’infiltration de solides dissous présents dans le concentré s'écoulant entre les premier et second orifices. Une pompe haute pression présente une entrée et une sortie. Une pompe de circulation est configurée pour faire circuler le concentré entre les premier et second orifices. La pompe de circulation présente une entrée et une sortie. Un appareil de circulation à soupape est conçu pour sélectionner un mode, entre un mode d'écoulement vers l'avant et un mode de décharge du système. Dans le mode d'écoulement vers l'avant, l'entrée de la pompe de circulation est raccordée au second orifice et la sortie de la pompe de circulation est raccordée au premier orifice. Dans le mode de décharge, l'entrée de la pompe de circulation est raccordée à l'entrée de pompe haute pression et la sortie de la pompe de circulation est raccordée au premier orifice.
