Acids and bases were obtained from a pilot-scale treatment plant as a result of the research. Furthermore, the sustainability and affordability of acids and bases obtained by EDBM systems were investigated. Six cycles were carried out in continuous-flow mode with the EDBM system as batch cycles in the disposal of the concentrate and the production of acids and bases with the EDBM system. For each cycle, the EDBM system was operated for 66, 48, 66, and 80 min, respectively, and the last two cycles were operated for a total of 165 min (70 + 90) with 5 min of waiting. In the EDBM system, a working method was determined such that the cycle flow rate was 180 L/hour, energy to be given to the system was 25 V, and the working pressure was in the range of 0.8-2.5 bar. In the six cycles with the EDBM system, the concentrate, acid and base, conductivity, pH, and pressure increase values were investigated depending on time. Throughout all these studies, the cycles were continued over the products formed in the acid and base chamber. As a result of all the cycles, acid (HCl) production at a level of 1.44% and base (NaOH) production at a level of 2% were obtained.eninfo:eu-repo/semantics/closedAccessDesalination brines productionInnovative beneficial reuseWaste-water treatmentAcidIntegrationSeparationNanofiltrationValorizationBrothNfElectrodialysis bipolar membraneConcentrateAcid recoveryBase recoveryMembraneScience & technologyLife sciences & biomedicinePhysical sciencesTechnologyBiochemistry & molecular biologyChemistry, physicalEngineering, chemicalMaterials science, multidisciplinaryPolymer scienceBiochemistry & molecular biologyChemistryEngineeringMaterials sciencePolymer scienceArticle00075705560000112110.3390/membranes12010083
