A new water filtration device was developed by Associate Professor Donglei (Emma) Fan, Department of Mechanical Engineering at Cockrell College of Engineering and a team at the University of Texas at Austin can store and filter water. They are inspired by the shape and structure of the rose tree. It has the advantage of low cost and the ability to filter 4.5 gallons of water per hour per square meter. This method takes advantage of solar energy to separate salts and other impurities from the water through the evaporation process.
Mr. Fan said: "We are optimizing the application of solar absorption technology by using a filter paper coated with a special polymer layer called polypyrrole" (polypyrrole has thermal properties, easy Convert from sunlight to geothermal to quickly evaporate).
In an article in the Advanced Materials scientific journal, the team used layers of filter paper to form petals that were connected to a water treatment tube. It has a simple, easy-to-handle structure that delivers the most amount of water filter possible. The structure of the paper layers allows sunlight to directly affect the thermal material from the inside. At the same time provide a wide enough surface to contain evaporation.
This water purifier can remove toxic substances from heavy metals or bacteria. In addition, it also filters salt from seawater to create clean water that meets the drinking water standards set by the World Health Organization (WHO).
