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.

Strong partitioning in polyamide negatively affects the rejection of organic contaminants in RO and NF filtration. The effect may be significant for larger contaminants having low solubility in water. In extreme cases this may counterbalance the sieving effect and limit the applicability of RO/NF to
