The aim of this project is to develop a highly efficient technology for producing plasma-activated water (PAW) with low energy consumption. The proposed research will build on strong partnership between researchers in University of Alberta and Disruptive Separation Technology Ltd. (DSLT) specialized in microbubble generation. Expected outcomes of the project will enable high throughput production of PAW to meet the urgent need for green and sustainable technology in agriculture, food and medical disinfection. PAW generated in large quantities will be at low cost without using chemicals in the formulation or leaving toxic by-products to the users or the environment. In this project, plasma treatment will be integrated with micro/nano- bubble technology to greatly improve the efficiency of plasma activation process. A suite of analytic techniques will be explored to understand the fundamental physiochemical properties of PAW that underlie the desirable activity. Quantitative relationship between activation conditions and physicochemical properties of PAW will be established. The activation efficiency will be significantly improved by bubbles so that the power input from solar panel will be sufficient for high throughput production of PAW on-site. PAW application for improved growth of plants will be demonstrated in greenhouse. The close collaboration among the industrial organization and the research team in the University will ensure that the research findings will be taken to the next level in development and commercialization. The project will create an excellent opportunity for training highly qualified personnel through partnership with the industry.
