A milk factory sited at Boudouaou (40 km from Algiers) rejects a great quantity of effluent which contains soft whey. 8,000 l are treated twice a week and are rejected into a river which supplies drinking water to the town population. Some analyses have shown an increase in the water acidity and bot

The reuse of water coming from electrolysis manufactory effluents is studied by means of the electrodeionisation technique. A neutral water stream which contains small quantities of zinc, copper, cadmium and lead is treated. Results obtained by electrodialysis and ion exchange by resins are presente

Donnan Dialysis is an adequate process to recover metals from dilute solutions, however, when the enrichment is needed, the osmosis phenomenon occurs and reduces the efficiency of the operation. Moreover, a lot of ion exchange membranes are so far from the ideal permselectivity. In this work, the co
