Summary:This disclosure describes draw solutions for FO processes which increase the available membrane area for permeation and are also This disclosure describes draw solution compositions for FO processes which increase the available membrane area for permeation and are also amenable to reconcentration with standard techniques, such as membrane filtration and evaporative technologies. The composition are comprised of a water soluble draw solute having surface active properties, i.e., a surfactant. La présente invention concerne des solutions d'extraction destinées à des procédés d'osmose directe (FO) qui augmentent la surface de membrane disponible pour la perméation et qui peuvent également être reconcentrées au moyen de techniques standard, telles que des technologies de filtration membranaire et par évaporation. Les compositions sont constituées par un soluté d'extraction soluble dans l'eau présentant des propriétés tensioactives, c'est-à-dire, un agent tensioactif.
