To fulfil the goals of circular economy, treatment textile wastewater should be focused on recovery valuable components. Monovalent anion-selective electrodialysis (MASED) was applied for separation reactive dyes from mineral salts. Standard cation-exchange membranes (CM membranes) and monovalent selective anion-exchange (MVA were used in (ED) stack. The efficiency evaluated model solutions various (varying molecular weight chemical reactivity) containing NaCl. In course MASED, salt successfully removed dye with an efficacy 97.4–99.4%, irrespectively composition treated solution. transport molecules through ion-exchange (IEMs) diluate to concentrate compartments irrelevant. Nonetheless, a significant adsorption particles observed. Around 11–40% initial mass deposited ED Dye intensity significantly affected by reactivity. This study showed potential MASED process condition that antifouling membrane properties are improved. obtained streams (the rich dye) can reused dye-house operations; however, some loss included.
