Abstract[English]
An apparatus and a method for seawater reverse osmosis controls mixing units to perform a first stage treatment of a liquid stream by adding a first set of chemical compounds to obtain a first liquid stream. The apparatus controls an ultrafiltration unit to perform a first stage purification by removing a first set of impurities to obtain a second liquid stream. The apparatus also controls a reverse osmosis (RO) membrane unit to remove a second set of chemical compounds by passing the second liquid stream through the RO membrane. The RO membrane outputs at least one of an RO brine stream and an RO permeate stream. The apparatus also controls an ion exchange unit to remove a third set of chemical compounds from the RO permeate stream to obtain a filtered liquid stream, and the apparatus stores the filtered liquid stream.[French]
L'invention concerne un appareil et un procédé d'osmose inverse d'eau de mer qui commandent des unités de mélange pour effectuer un traitement de premier étage d'un flux de liquide par ajout d'un premier ensemble de composés chimiques pour obtenir un premier flux de liquide. L'appareil commande à une unité d'ultrafiltration d'effectuer une purification de premier étage par élimination d'un premier ensemble d'impuretés pour obtenir un second flux de liquide. L'appareil commande également à une unité de membrane d'osmose inverse (OI) d'éliminer un deuxième ensemble de composés chimiques en faisant passer le second flux de liquide à travers la membrane d'OI. La membrane d'OI délivre un flux de saumure d'OI et/ou un flux de perméat d'OI. L'appareil commande également à une unité d'échange d'ions d'éliminer un troisième ensemble de composés chimiques du flux de perméat d'OI pour obtenir un flux de liquide filtré, et l'appareil stocke le flux de liquide filtré.
