Recycling by electrodialysis: from lab to industrial applications

The purpose of this paper is to describe an experimental method developed to study the use of electrodialysis (ED) as a recycling process introduced within some operations in the surface treatment industry. The case study is acid picking before electroplating. The first step is the study and selection of ion-exchange membrane couples. The second step is the development of tools to promote the use of ED applied to industry. Tracer methods and surface treatment models are described.
