Forward Osmosis System And Process

Abstract

A forward osmosis fluid purification system includes a cross-flow membrane module with a membrane, a channel on each side of the membrane which allows a feed solution and a draw solution to flow through separately, a feed side, a draw side including a draw solute, where the draw solute includes an aryl sulfonate salt. The system can be used in a process to extract water from impure water, such as wastewater or seawater. The purified water can be applied to arid land.
