Title
(EN) SYSTEM FOR CONTINUOUS EXTRACTION OF PURE WATER FROM FEEDS WITH RESATURATION AND REUSE OF DRAW
(FR) SYSTÈME D'EXTRACTION CONTINUE D'EAU PURE À PARTIR DE CHARGE D'ALIMENTATION AVEC UNE RESATURATION ET UNE RÉUTILISATION DE L'EXTRACTION
Abstract
(EN)
The present invention relates to a Forward Osmosis-based system and process for continuous extraction of pure water directly into industrial starting materials through their use in the form of draw solutions with recycle and reuse of minor portion of the outlet draw in subsequent cycles while the major portion is made 5 available for industrial use. The invention helps provide a practical and energy efficient alternative to processes such as RO, and with reduced fouling problem, where the ultimate objective of RO is to supply pure water as dissolution medium.
(FR)
La présente invention concerne un système et un procédé à base d'osmose directe pour l'extraction continue d'eau pure directement dans des matières premières industrielle à travers leur utilisation sous la forme de solutions d'extraction avec recyclage et réutilisation d'une partie mineure de l'extraction de sortie dans des cycles ultérieurs tandis que la partie principale est rendue disponible pour une utilisation industrielle. L'invention contribue à une alternative pratique et économe en énergie à des procédés tels que RO, et à un problème d'encrassement réduit, l'objectif final de RO étant de fournir de l'eau pure en tant que milieu de dissolution.
