Water-Wise Cities are cities in which 1) we reduce wastage of water and energy, 2) we reuse water and recover the energy from water, and 3) we replenish the environment by ensuring adequate water quality and quantities are available. In this session, we will discuss the concept and origin of Water-Wise City and political, economic, social, and environmental strategies to achieve it.
- Seawater desalination has been an irreplaceable technology to produce fresh water in a large-scale for human use and undoubtedly be key-technology for building Water-wise city. Desalination via reverse osmosis, in particular, has gather more attention to such an extent as to account for more than 60% of total desalination process. In this session, several outstanding ideas and attempts in reverse osmosis process will be presented by speakers from academia and industries, as well.
- There has been a growing interest in rainwater recycling circulation for Waterfront City. The session shows how to approach the green-infra and low impact development technology to improve urban flood, the distortion of water recycle, water quality, etc., worsened by the urbanization and climate change. It also presents a way to maintain sustainable water-cycle systems in cities.
- Conventional activated sludge process for municipal wastewater treatment is highly energy intensive, due to the need for large amount of air into the biological process. Recent novel and energy-efficient wastewater treatment processes based on the anaerobic organic removal followed by anammox process for nitrogen removal without organics will be introduced and discussed in this session.
- As the damage of natural disaster accelerated by climate change, there area need for national hazard mitigation plan considering urban sustainability and hazard mitigation measures at local level through water management. This session presents the necessity and implementation strategy of national hazard mitigation plan and suggests importance of Low Impact Development(LID) technology to establish hazard mitigation measures at local level. This session also discuss future direction of hazard mitigation plan for climate change adaptation.
- With the increase in the desire for health and well-being, it has become a trend that demands more rigorous quality control of city water. Growing interest in micropollutants and non-biodegradable pollutants in water source requires a new water treatment technology. Accordingly, membrane and UV-AOP process, which can be the future of water technology, has engaged public attention and there have been much research and experience on them. Under the theme of “Advanced Technologies for Water Treatment,” the 5th Busan Global water Forum consists of special sessions and a symposium hostedby the water quality laboratory at Busan Water Authority. In this symposium, several research results, technology, and practices in UV/AOP and membrane will be presented by experts at home and abroad.
