Invention:
This invention is a photocatalytic water purification system that utilizes ultrathin metal oxide film deposited on reflective substrates to enhance light absorption and increase overall efficiency of water purification in a variety of small- and large-scale applications. The metal oxide film is engineered to absorb light optimally at the interface between the film and the substrate, creating conditions that increase the generation of reactive oxygen species for enhanced photocatalytic reactions, which are crucial for the breakdown of contaminants. This design allows for efficient degradation of pollutants and pathogens in water using minimal amounts of metal oxide, reducing material costs and environmental impact. The system is designed to operate effectively under various light sources, including natural sunlight and artificial illumination, making it versatile for diverse applications. The technology is suitable for integration into compact and scalable water purification devices, such as portable water purifiers, wastewater treatment systems, as well as integration into existing water infrastructure for enhanced purification.
Background:
As of 2020, wide disparities among the regional proportions of household wastewater safely treated were discovered (ranging from 25-80% by SDG region), indicating that progress remains uneven across the globe. Typical methods of water purification, such as reverse osmosis, are disadvantageous due to their lengthy processes, high operating costs, and scalability issues. This method of water purification via photocatalysis allows for a more efficient approach to water treatment by maximizing photocatalytic activity and decreases sensitivity to common barriers allowing for implementation into compact and scalable water purification devices.
