In this study, the feasibility of Forward–Reverse osmosis processes was investigated for treating oily wastewater. The first stage applied forward process to recover pure water from Sodium chloride (NaCl) and magnesium (MgCl2) salts were used as draw solutions membrane that in (FO) cellulose triacetate (CTA) membrane. operating parameters studied were: solution concentrations (0.25 – 0.75 M), o...

Forward osmosis (FO) as emerging technology for water treatment was reported to exhibit higher solute rejections compared reverse (RO). In this work, the rejection of two uncharged organic compounds (nicotinamide, caffeine) were investigated first time in low-pressure (LPRO) mode and FO under similar process conditions utilizing same hollow fiber forward membrane modules. consistently showed th...

The use of forward osmosis (FO) is of growing interest for water desalination, due to its potential energy savings. However, its industrial implementation is still limited by its actual performance limitation inwater permeation and reverse salt diffusion, due to membrane properties. Assisted forward osmosis (AFO) is a new concept, aiming at pressurising the feed solution to enhance water permea...
