Re ECF Project: 2014-70

Project Title: The 12th International Water Association (IWA) Leading-Edge Conference on Water and Wastewater Technologies

Applicant: Prof. Guanghao CHEN of The Hong Kong University of Science and Technology

Total Approved Grant: $400,000 or 70% of the total actual expenditure, whichever will be the less.

Duration: 25/8/2014 to 15/9/2015

Project Status/Remarks: Completed

This project aims to bring together leading researchers, technologies and water experts from all over the globe to enhance co-operation, and to make a marked contribution to the goal of providing safe water for everyone. It also facilitates the exchange of best practices, expertise and experience on the emerging issue of waste reduction and recycling. The conference will also host a tailor-made workshop for local environmental policy makers, regulators and practitioners to tap the expertise in the co-treatment of organic solid wastes in the sewage treatment facilities for waste reduction and energy recovery.

Summary of the Findings/Outcomes:
This IWA Leading Edge conference brought together water leaders, technicians and academics to focus on both innovation and scaling up from pilot to full application, in total 8 major schemes of leading edge technologies: 1) alternative watersources, 2) treating complex industrial wastewaters, 3) direct potable reuse, 4) integrated chemical and biological treatment, 5) E-technology, 6) Resource recovery from wastewater, 7) water technology for densely populated cities, and 8) granular sludge process. 3 workshops and 2 technical visits wre carried out for the topics; among them, the core workshop was tailor-made for HK, to intensively discuss on the food waste management, to convert question from waste treatment to resource recovery. At the conference, science, social sciences and the industrial perspective coalesced to highlight solutions through sharing experiences and lessons learned: 1) using the alternative water sources such as recycled water and seawater in Hong Kong, Japan and South Africa, and 2) managing the relationship between the technological innovation, social acceptance, and transparent communication to showing the treatment processes and risks.
