Under increasing climate change pressures and growing freshwater scarcity, the textile industry urgently needs innovative, low-cost, and sustainable wastewater treatment technologies. This study explores the use of palm waste, an abundant lignocellulosic by-product in arid regions, as an eco-friendly adsorbent for textile effluent purification. A pilot-scale prototype was developed and tested under dynamic flow conditions to evaluate treatment performance, regeneration behavior, and economic feasibility. Results showed pollutant removal efficiencies exceeding 85-95.7%, with total suspended solids and organic loads effectively reduced over three to five regeneration cycles using a simple ethanol-water washing step. The system also achieved a 90% reduction in water costs, confirming its strong potential for industrial water reuse. Complementary kinetic modeling with cationic and anionic model pollutants validated the chemisorption-driven mechanism. Overall, this work demonstrates the technical, economic, and environmental viability of palm-waste-based filters, aligning with national water reuse strategies and circular economy goals for sustainable resource management.
