H2nanO provides solutions for environmental challenges using the power of nanotechnology. Our reusable, light-activated system destroys hard-to-treat contaminants such as petrochemicals, pharmaceuticals and dyes in industrial wastewater. H2nanO's nano-enabled catalyst uses the UV-lamps or direct sunlight to break down persistent, toxic organic contaminants. We build in recovery from the bottom up with proprietary composites that enable safe and scalable nanomaterial use. We provide low-cost advanced oxidative process treatments that generate no wastes or by-products, making H2nanO the ideal choice for industrial scale treatment.
