A research team funded in the Aqua-Pulse project has developed a smart water purification method based on the use of ultraviolet rays and photocatalysis, a chemical reaction caused by the use of light.
The scientists built a radiator, which consists of a titanium dioxide coating and a diode which emits UV light directly onto bacteria and viruses, killing them in the process.
According to the researchers, the new method is more eco-friendly than using mercury lamps and more powerful than purifying water with chlorine.
