Abstract

The discharge of dye-containing effluents from textile industries poses a significant environmental challenge due to their toxicity, persistence, and resistance to biodegradation. In this study, a laboratory-scale electrodialysis (ED) system was developed to treat synthetic wastewater containing a model textile dye (Drim Black), with emphasis on cell design, operating conditions, and performance evaluation. The ED cell was fabricated from acrylic and comprised alternating cation- and anion-exchange membranes, carbon clothsupported electrodes (aluminium anode and copper cathode), and a peristaltic feedback loop. Dye removal was monitored by UV-Vis spectrophotometry at 590 nm using a calibration curve (1-20 ppm). Under optimized conditions (12 V, 15 ppm dye, 120 min), the system achieved >90% decolorization, with absorbance declining to ~0.01 (97% removal). Conductivity in the dilute stream decreased by ~70%, indicating efficient ion extraction, while solution pH remained near neutrality due to electrode reactions. Energy consumption was relatively low (~0.5 A at 12 V for 1 h), highlighting the economic feasibility of the process. The results demonstrate that electrodialysis with carbon cloth and sacrificial electrodes offers a cost-effective, energy-efficient, and environmentally sustainable approach for textile dye wastewater treatment. This work underscores the potential of ED technology as a climate-resilient alternative for industrial effluent management, minimizing chemical usage while ensuring high pollutant removal.
