Project Details


This research project aims to devise a green sustainable process based on reactive nanobubbles (NBs) technology to control and mitigate harmful algal blooms (HABs). NBs may potentially be produced with air, oxygen, ozone or other reactive gases that promote rapid oxidation and decomposition of algae and associated organic contaminants (e.g., cyanotoxin). Although there has been a growing number of NBs applications (e.g., detergent-free cleaning, water aeration, ultra-sound imaging and intracellular drug delivery, and mineral processing), its potential as a water purification technology remains largely unexplored. The fundamental chemistry of NBs and antimicrobial mechanisms are also not well understood. Accordingly, this project aim to address knowledge gaps to better understand and utilize the unique characteristics of NBs (such as high colloidal stability) and high reactivity (e.g., radical formation) in water dispersion for environmental applications. Our project aims to provide a green technology to protect human health and water quality, especially for impaired water bodies in suburban or rural areas and communities, where the advanced centralized water treatment facilities are lacking.
