Researchers in the Faculty of Science at the University of Calgary, led by Dr. Peter Kusalik, PhD, and Dr. Susana Kimura Hara, PhD, are developing an energy-efficient method for generating nanobubbles tiny bubbles with a range of applications including wastewater treatment and brewing.
Current methods of producing nanobubbles consume excessive energy. The researchers are exploring a novel approach using electric fields to create nanobubbles, reducing energy consumption and also enhancing the bubbles' unique properties, making them valuable for various sectors.
"When I introduce nanobubbles into water, I've introduced a whole bunch of extra surface into the system, which is a highly reactive environment that can lead to a lot of interesting chemistries going on," Kusalik explains.
For instance, nanobubbles can improve water disinfection processes by introducing ozone to degrade contaminants. One project found that seedlings watered with nanobubble-infused water grew 40% more than those watered with regular water. Other research found the large surface area of nanobubbles enhanced the dissolution of gases necessary for the fermentation process of beer, improving the final product.
