This technology applies to any system where removal of toxic industrial chemicals and pathogens are present in water, and where robust, reliable operation with minimal supply logistics is required. The primary application of the AWPS is to provide a compact, high performance wastewater purification device for spacecraft environmental control and life support system (ECLSS) for extending NASA's mission beyond low earth orbit to include long-duration space habitation, Lunar, and Mars colonization missions. This is accomplished by the advanced AWPS device which combines energy efficient UV LED-based source illumination, high photon utilization, highly active photocatalysts, high reactor surface-to volume, in situ reactant use, and low temperature and pressure operation. The technology has numerous applications in municipal water treatment and commercial sectors including pharmaceuticals, food processing, cosmetics, electronics, oil and gas industries, and hospitals. Other government agencies such as the Department of Defense and First Responders would benefit from this technology as a portable water treatment technology against chemical and biological pathogens. The AWPS technology is well suited for the growing market demand of wastewater equipment and is poised to solve a variety of industrial water treatment challenges with minimal environmental impact. The AWPS technology is composed of entirely green chemistry- just light, iron oxide, and environmentally friendly on-site generation of hydrogen peroxide. This technology leads to the facile generation of hydroxyl radical chemistry, which is vital to the complete destruction of industrial chemicals in water. No addition of chlorine is needed and therefore deleterious chlorine byproducts are not generated.
