Title (EN) DESALINATION
(FR) DESSALEMENT
Abstract:
(EN) A membrane stack comprising the following components: (a) a first ion diluting compartment (D1); (b) a second ion diluting compartment (D2); (c) a first ion concentrating compartment (C1); (d) a second ion concentrating compartment (C2); and (e) a membrane wall (CEM1, mAEM, mCEM, AEM, CEM2) between each compartment and on the outside of the first and last compartment of the stack; wherein: (i) each membrane wall comprises a cation exchange membrane (CEM1, mCEM, CEM2) or an anion exchange membrane (mAEM, AEM) and the order of the cation and anion exchange membranes alternates from each wall to the next; (ii) the membrane walls (mAEM, mCEM) on each side of compartment (a) both have a higher monovalent ion selectivity than the corresponding membrane walls (AEM, CEM2) on each side of compartment (b); and (iii) the stack further comprises a means for communicating fluid between compartments (a) and (b).
(FR) L'invention concerne un empilement de membranes comprenant les éléments suivants : (a) un premier compartiment de dilution d'ion (D1) ; (b) un second compartiment de dilution d'ion (D2) ; (c) un premier compartiment de concentration d'ion (C1) ; (d) un second compartiment de concentration d'ion (C2) ; et (e) une paroi de membrane (CEM1, mAEM, mCEM, AEM, CEM2) entre chaque compartiment et sur l'extérieur des premier et dernier compartiments de l'empilement ; (i) chaque paroi de membrane comprenant une membrane d'échange de cation (CEM1, mCEM, CEM2) ou une membrane d'échange d'anion (mAEM, AEM) et l'ordre des membranes d'échange de cation et d'anion étant alterné de chaque paroi à la suivante ; (ii) les parois de membrane (mAEM, mCEM) sur chaque côté du compartiment (a) ayant une sélectivité d'ion monovalent plus grande que les parois de membrane correspondantes (AEM, CEM2) sur chaque côté du compartiment (b) ; et (iii) l'empilement comprenant en outre un moyen de communication de fluide entre les compartiments (a) et (b).
