In this project, the scientists in water science and technology have teamed up with researchers in membrane science, chemistry, toxicology, and engineering to develop a new ground-breaking water system for wastewater treatment and effluent reuse/recycle, with the ultimate goal of mitigating water scarcity. The resulting fully-integrated, compact wastewater-to-resource facility (WWRF) will feature novel technologies (new membrane, AOPs, biotreatment, and resource recovery technologies) for significant production of potable water and expensive biochemicals from saline wastewater, with minimal brine and biological sludge.
As a scientific contribution, the proposed research will demonstrate our total (saline, fresh, grey and brine) water concept through the ‘water is water, resource is resource’ approach. In the near term, the outcomes of the project will facilitate HK in retrofitting conventional water plants or implementing a ground-breaking water system in new town developments to offer an alternative potable water source. In the mid-term, the project will ease the issue of freshwater scarcity on islands and in coastal areas. Through this project, we can make HK the world’s hub for new water resource research and help other water-scarce regions to fulfill the UN’s goals for water, agriculture, sanitation, and hygiene simultaneously.
