Water Recovery from Brine Solution by Forward Osmosis Process

The present work aims to study the possibility of utilization a forward osmosis desalination process as an alternative method extract water from brine solution rejected reverse process. Experiments conducted in laboratory–scale (FO) unit cross flow flat sheet membrane cell yielded flux ranging (0.0315 0.56 L/m2 .min) when using CTA membrane,and (0.419 2.785 for PA under 0.4 bar. Two possible orientations were tested. Sodium chloride with high concentrations was used draw solute. effect orientation on internal concentration polarization (ICP) studied. regimes ICP; dilutive and concentrative described characterized their governing equations applied. Also feed rate It found that experimental lower than theoretical flux. Using pressure resulted higher desalinated alone without same operating conditions.
