Title (EN) REVERSE OSMOSIS FILTER FLUSH DEVICE AND METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE RINÇAGE DE FILTRE D'OSMOSE INVERSE
Abstract: front page image
(EN)An apparatus and method for reversing the flow in a reverse osmosis system is described utilizing a single unitary valve. The improved system and method provides a means to reduce operating costs, maintenance and down time associated with a reverse osmosis system by providing a reliable and robust means to reverse the flow of fluid thereby flushing filter membranes.
(FR)La présente invention concerne un appareil et un procédé d'inversion du flux dans un système d'osmose inverse utilisant une soupape monobloc unique. Le système et le procédé améliorés fournissent un moyen de réduction des coûts de fonctionnement, de l'entretien et de la durée d'indisponibilité associés à un système d'osmose inverse en fournissant un moyen fiable et robuste d'inversion du flux de fluide, rinçant ainsi les membranes du filtre.
