Water scarcity poses a critical global challenge, especially in arid and semi-arid regions where freshwater resources are extremely limited. Addressing this issue requires innovative and sustainable wastewater treatment technologies. This study introduces a solar-powered Zero Liquid Discharge (ZDD) system for industrial wastewater treatment. It integrates physico-chemical pretreatment to remove suspended solids and hardness-causing compounds, followed by multi-stage solar evaporation ponds enhanced with nanostructured absorbers to maximize heat conversion. Microfluidic channels ensure uniform flow and double evaporation rates. Thermal energy stored in phase-change materials enables continuous operation, including nighttime. The condensed vapor produces high-quality freshwater, while valuable salts and minerals are recovered. This low-energy, membrane-free system offers a sustainable solution for wastewater valorization and water resource management.
