Severe water scarcity in off-grid desert-edge and coastal communities requires desalination methods and contamination removal that are independent of energy-intensive such as reverse osmoses methods that requires about 3 to 5.5 kWh per cubic meter of water. This solution presents a cost-effective, solar-powered system designed to remove a wide range of contaminants then desalinate it by distillation. synthetic zeolite A, synthesized from kaolinite, adsorbs heavy metals and minimizes the chemical oxygen demand (COD). Concurrently, an osmotic-pressure-driven hydrogel formed from poly sodium acrylate, methylenebisacrylamide, ammonium persulfate for absorbing water and making salt rejection, and polyaniline for enhancing light absorption incorporated in a loofah sponge.
