Water purifier inspired by rose tree

Filter paper coated with a special polymer increases the possibility of water evaporation, creating a water source that meets WHO standards.

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 purify water, take 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 science journal, the team used layers of flower-shaped filter paper connected to a water treatment tube, a simple structure that was easy to handle to bring in the amount of water as much as possible. The structure of the layers of paper allows sunlight to directly affect the thermal material from the inside and provides a surface large enough to contain water evaporation.

This water purifier can remove toxic substances from heavy metals or bacteria, filter salt from seawater, create clean water sources that meet drinking water standards set by the World Health Organization (WHO). .
