“…Several studies comparing desalination technologies with electrodialysis were performed on groundwater, surface water and effluents [22,27,34,38]. These studies led to favorable evaluation of electrodialysis because of several factors, such as: high recovery, simple pretreatment of the feed water, less susceptibility to fouling and deposits and lower operating costs.…”

This chapter focuses on the uses of electrodialysis and specially electrodialysis reversal for the treatment of brackish and groundwater to produce drinking water. Over the last 10-15 years, numerous advances in membrane and system technologies have made EDR an especially attractive technology, both in terms of performance and cost effectiveness. Many applications of EDR technology can be found around the world and different applications are shown here.

“…Indeed, ED/EDR has earned a reputation as a membrane desalination process that works economically and reliably on surface water supplies [23][24][25], reuse water [26][27][28] and some specific industrial applications [29,30] when designed and operated properly [31]. Thus, several studies were interested, especially on CaCO 3 and/or CaSO 4 scale formation risk on the common ED stacks and membranes [32][33][34][35][36][37][38][39].…”

The composition of feed water used in electrodialysis (ED) desalination causes the risk of CaCO 3 scale crystallization in ED equipments, which leads to the decrease of process efficiency. To control scaling in water systems, several scaling indices and tests, permitting to predict the scaling occurrence, have been devised. In this study, an accelerated scaling test allowing to follow CaCO 3 formation in water desalination plant using ED process was proposed. Tests were performed using a pilot unit as a conventional ED in batch recirculation mode. By simple in situ measurements of pH and flow rate of the concentrate, the crystallization onset and growth of CaCO 3 were followed during the pilot operation. This leads to precise determination of the number of concentrate recirculation times and therefore to the highest recovery rate without scaling risk as a function of the inlet water quality and the antiscale pretreatment.
