The disruption of electricity supply often renders conventional water treatment processes no longer reliable. An ideal treatment technology for disaster relief and less developing regions should be electricity- chemical-free, compact, and highly efficient with the ability to remove contaminant instantaneously. Our team developed a simple yet effective adsorptive filtration device to removal heavy metals (> 99.9%) or bacteria (> 99.9999%) without the need of electricity supply. The filtration can be driven by gravity force - a few centimetres of water height is enough to achieve water permeation. The membrane is designed to be regenerable to enable it being sustainable used.

About Guo Hao

Hao is now a Postdoc Fellow from the Department of Civil Engineering at The University of Hong Kong (HKU). He received his B.Eng from the Wuhan University of Technology in 2010, his M.Eng from the Huazhong University of Science & Technology in 2013, and his Ph.D. from HKU in 2017. His research mainly works with the fundamental mechanism investigation and novel materials development in advanced membrane-based water treatment and seawater desalination for sustainable water production.
