This study aimed to use the bipolar electrodialysis process that contains bipolar membranes, cation and anion exchange, and an electric field that deionized water and elaborate NaOH and HCl from NaCl. A pilot model of electrodialysis with a cell configurated in (B + A +C + B) device’s operational parameters was evaluated by using the standard solution of NaCl as indicated in the Taguchi method. The results showed that the voltage was 15V; the flow was 400ml per minute; the initial concentration of acid-base was 0.05N and the brine concentration, was 50 g/l de NaCl in 240 minutes. The acid concentrates in 0.16N, the base in 0.132N, which it demonstrates current efficiencies to 90% and a mathematic model was determined to the acid concentration = 6×10^(-4) + 206×10^(-4), and the base concentration = 5×10^(-4) + 174×10^(-4). After 30 hours, an extrapolation of the module operation was performed and the concentrated solution was 1.1N to acid and 0.9174N to the base. desalination electrodialysis bipolar membranes acid base Full Text Additional Declarations No competing interests reported.
