Title
(EN) OSMOTIC PRESSURE ASSISTED REVERSE OSMOSIS PROCESS AND METHOD OF USING THE SAME
(ZH) 渗透压辅助的反渗透法及其使用方法
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 reverseosmosis 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 feedsolution stream and a diluted second feed solution stream. Devices and systems for performing the processes are provided.
