Hi! I’m Ahmed Hosny, I’m 17-year-old from Giza, Egypt, and I am currently senior at Obour STEM School. I’m passionate about environmental engineering, especially water-scarcity challenges, and I love turning classroom science into real-world solutions.
Tell us what the water concern in your country is!Egypt relies on the Nile for about 90% of its freshwater, yet we are below the UN “absolute scarcity” line. Rapid population growth and 80% agricultural intensify the pressure. At the same time, untreated agricultural and industrial waste was thrown into the river. Together these problems affect drinking water supplies.
AI-Optimized Hydrogel-Zeolite Photocatalytic Wastewater Purifier
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.
