(EN) OSMOTIC PRESSURE ASSISTED REVERSE OSMOSIS PROCESS AND METHOD OF USING THE SAME
(FR) PROCÉDÉ D'OSMOSE INVERSE ASSISTÉ PAR PRESSION OSMOTIQUE ET PROCÉDÉ D'UTILISATION DE CELUI-CI
Abstract:
(EN) Devices, methods, and systems for producing a concentrated feed stream and a diluted feed stream using a solute stream provided to the low pressure side of the semi-permeable membrane during a reverse osmosis process. The process includes providing a semipermeable membrane having a first side and a second side and introducing a first feed solution stream on the first side of the membrane and a second feed solution stream on the second side, wherein the osmotic pressure of the of the first feed solution stream is greater than or equal to the osmotic pressure of the second feed solution stream. The process further includes exerting hydrostatic pressure on the first side of the membrane such that solvent passes from the first side to the second side thereby producing a concentrated first feed solution stream and a diluted second feed solution stream. Devices and systems for performing the processes are provided.
(FR) La présente invention concerne des dispositifs, des procédés et des systèmes pour produire un flux d’alimentation concentré et un flux d’alimentation dilué au moyen d’un flux de soluté fourni vers le côté de base pression de la membrane semi-perméable pendant un processus d’osmose inverse. Le procédé comprend la fourniture d’une membrane semi-perméable ayant un premier côté et un deuxième côté et l’introduction d’un premier flux de solution d’alimentation sur le premier côté de la membrane et d’un deuxième flux de solution d’alimentation sur le deuxième côté, la pression osmotique du premier flux de solution d’alimentation étant supérieure ou égale à la pression osmotique du deuxième flux de solution d’alimentation. Le procédé comprend en outre l’application d’une pression hydrostatique sur le premier côté de la membrane de sorte que le solvant passe du premier côté vers le deuxième côté de manière à produire un premier flux de solution d’alimentation concentrée et un deuxième flux de solution d’alimentation diluée. L’invention concerne en outre des dispositifs et des systèmes pour conduire les procédés.
