Abstract

As far as the reduction of the environmental impact of production processes is concerned, the management ofliquid wastes of high salinity remains a key point. In this paper, the possibility to use electrodialysis for the improvement of the management of such problematic liquid wastes is investigated. The ED experiments are carried out to investigate the influence of the operating parameters on the ED performances, i.e. on the variation of the organic loss factor versus the demineralisation factor. It is demonstrated that the demineralisation can be accompanied by a change in the mineral composition, i.e. an increase of the sulphate to chloride ratio. A concentration limit is pointed out. Then, the influence of the salt composition on the biological degradation is investigated
