Water Purification Filter Only Requires Sunlight to Work

A photo-thermal water purifier using titanium dioxide nanowires (TiO2NWs) proves to be a viable water filtration system for worldwide commercial applications, according to a recent study published on npj Clean Water.

A photocatalytic filtration system may help solve the global issue of limited access to clean drinking water. This system utilizes nano-variants of titanium dioxide (TiO2), a known semiconductor that can capture ultraviolet (UV) portions of the light spectrum using its large bandgap.

TiO2 nanoparticles (TiO2NPs) produce reactive oxygen species (ROS) by creating an electron hole-pair through sunlight absorption and combining it with water and oxygen. A filtration system that capitalizes on ROS’s capability to eliminate aquatic microbes and pollutants provides an alternative disinfection method for isolated, rural, or war-affected regions and communities.

At present, no photo-thermal TiO2-based system is available yet. The study, however, shows the benefits of using the said strategy to purify water and may set a precedent for future developments.

We look forward to seeing functional photocatalytic TiO2-based systems soon, as providing clean, purified water is essential to Aqua Solutions. We support innovative water purification solutions and recommend the Type I Reagent Grade DI Systems for operations using either ordinary tap water or pretreated water.
