To allow water recycling and nutrient recovery from reverse osmosis (RO) concentrates from a food industry plant, separation of salts from the organic fraction and from nutrient anions is required. In this study, the use of ion-exchange membranes in electrodialysis was investigated to this purpose.

The Hsgfeldt three-parameter model has been applied to nitrate-chloride ion exchange in diluted and in concentrated solutions. The three parameters of the model have been calculated and their variation with tlqe water activity of the solution, the crosslinking degree of the resin, and the nature of
