A hybrid process combining reverse osmosis and electrodialysis has been shown to be effective in recovering 97–98% of brackish water as product water with chloride levels of 200 mg/L or less. Potential for scaling on the brine side of the electrodialysis unit was prevented by acidification, operating

Boron removal from desalinated seawater is studied. Electrodialysis with improved ionic spacers and modified anion exchange membranes is used for this purpose.

Flat sheet samples of SWRO membranes of the SWC2 type (Hydranautics) were surface modified with hydrophilic polymers formed by redox initiated grafting with vinyl monomers. These were mounted on specially designed stubs along with unmodified membranes and tested at the Mekorot seawater RO pilot plan
