Electric-field nanobubbles: Re-engineering water treatment

Electric-field nanobubbles: Re-engineering water treatment Niall J. English, from the University College Dublin, School of Chemical and Bioprocess Engineering, discusses electric-field generated nanobubbles, including re-engineering water treatment – and beyond. A major and fundamental challenge is limited solubility in many liquids, e.g., gases, such as oxygen, and especially hydrogen, in water. In ecosystems and the environment, lack of dissolved oxygen (DO) is a significant reason for fish kills and water bodies being blighted by algal blooms, in addition to sometimes lack of effectiveness concerning activated-sludge processes in water treatment or poorer-than-hoped results in irrigation.
