Clean water and clean air are vital for public health. This project focuses on developing high-efficiency and environmentally sustainable filters for removing harmful air/water pollutants. The team has developed novel architectures and functionalities for the filters to achieve high permeance, high removal efficiency, and excellent reusability.
All members of the HKU community and the general public are welcome to join!

Engineers traditionally construct networks of drains and pipes to efficiently divert rainwater away from urban areas. However, such conventional approaches do not focus on addressing environmental issues caused by urbanization, such as water quality degradation and reduced groundwater recharge. Nature-based solutions (NBS) are urban rainwater management approaches that support the natural cycle of water and utilize ecosystems’ functions. Commonly used NBS include bioretention cells, porous pavements, and river hyporheic restoration measures. NBS can simultaneously provide multiple benefits in addition to rainwater quantity and quality management, such as promoting biodiversity, increasing aesthetic values, and reducing urban heat island effects. In this TechTalk, Dr. Chui will introduce some NBS and discuss the opportunities and challenges of implementing them in Hong Kong.
