Overview of innovation

This invention introduces a photocatalytic water filtration system designed to purify contaminated water using nanotechnology, capillary coils, and light-activated self-cleaning filtration. The system incorporates a spongy nanofiber-based photocatalytic filter bed within coiled capillary tubes. When exposed to sunlight or artificial LED light, the embedded metal oxide and carbonaceous nanoparticles degrade pollutants, making the filter self-regenerating. The system is powered optionally by solar panels and rechargeable batteries, making it suitable for off-grid use.
