Scientists in Korea have created a new way to clean water using special ceramic filters. These filters can remove tiny, harmful things in water, even when the water isn’t pushed through with a lot of pressure. This new method is better for the environment, uses less energy, and is easier to use than older ways of cleaning water. Dr. Hong-Ju Lee, who led the study, said that this new technology can make water filters that work well and don’t have any defects, even when they’re working with low water pressure. The team used a special method called ‘mutual doping’ to make the filters stronger and more reliable. They also lowered the temperature needed to make the filters, which makes the process safer and more efficient. The filters are so smooth that they don’t crack easily, and they can remove almost all the dye from dirty water while letting safe salt ions pass through. This new technology could help us not just clean water, but also recover useful things from it. The team is now working on making this technology bigger and testing it on a larger scale.
