Ion-exchange membrane

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 selecti

This paper first presents a set of experimental data on the measurements of the ionic fluxes through a cationexchange membrane separating two electrolyte solutions with the same concentration, the same co-ion but different counter-ions (bi-ionic system). Then these results are compared with the theo

An electrodeionization post-reverse osmosis (RO/EDI) system was developed for the continuous production of high-purity water without the use of chemicals. The study was carried out with a laboratory pilot. The ion-exchange membrane stack has eight cell-pairs of which four dilute compartments were fi
