Performance of Commercial Asymmetric Cellulose Acetate Membrane Compared to Polydopamine Modified Thin Film Composite Membranes for Forward Osmosis
In forward osmosis applications the cellulose acetate (CA) membrane offers the best performance but carries the limitation of not tolerating a basic feed water. This characteristic eliminates the CA membrane from use with the ammonia-carbon dioxide (NH3-CO2) draw solution. Treatment of conventional reverse osmosis membrane with polydopamine improve...
Cation Exchange in Forward Osmosis: Study of pH Effects and Alternative Selective Layers to Mitigate it
This paper discusses research aimed at reducing cation exchange in Forward osmosis membranes. The effect of pH and modifying the FO membrane are reported....
