Feasibility of Nano-Ozone Bubbles to Treat Drinking Water

Nanobubbles are nano-scopic gases in aqueous solutions that have the ability to change the normal characteristics of water and can oxidize contaminants, thus indicating tremendous potential for the purification of drinking water. Although they are extremely stable and have a much longer lifespan than larger bubbles, there are many unanswered questions such as the reason for the long term-stability and eventual dissolution. In this study we are examining the surface charge density and Brownian motion of the bubbles, as well as the electrical conductivity of the fluid, using molecular modeling techniques and advanced instrumentation. These underlying factors have been proven to significantly influence ozone nanobubble stability, and pave the way for the development of an effective, yet sustainable water treatment process.

Shaini Dilsha Aluthgun Hewage, MSc, PhD Student, New Jersey Institute of Technology, USA.

Shaini Aluthgun Hewage is a PhD student at New Jersey Institute of Technology, USA, in the Civil and Environmental Engineering Department. She did her MSc in Geotechnocal and Earth Resources Engineering from Asian Institute of Technology, Thailand in 2015 and completed the BSc in Civil and Infrastructure Engineering from Asian Institute of Technology, Thailand in 2013. Currently, she is a Teaching/Research assistant at NJIT. Her research area focuses on nanobubbles in aqueous solution and their stability and behavior as well as their applications are studied. She considers the experimental study as well as the theoretical study based on Molecular Dynamic analysis for understanding the nanobubbles behavior. Also, she is contributing to the studies and experiments on the application of nanobubbles for water treatment as well as the contaminate soil treatment. Before starting her PhD, she worked as a civil/structural Engineer at Fong Consult Pte Ltd, Sri Lanka, in 2015.
