Effect of Gas Flow Rate on the Solubility and Lifetime of Liquid-Rotated Aerator Generated-Microbubbles

Ozone was adopted to be an alternative technology for the elimination of various kinds micropollutants. However, ozonation is still limited by poor ozone dissolution in water. Microbubble proposed overcome this limitation. This paper aimed investigate effect inlet gas flow rate on production and solubility liquid phase. A double dielectric barrier discharge (DDBD) -based generator used connected a microbubble aerator. concentration measured both outlet points water under rates. In addition, lifetime best-ozonated micro-bubbles (OMB) investigated storing them at two different temperatures. The application lower increased concentration, which can increase mass input resulted better solubility. Furthermore, size generated bubbles known finer as decrease Lastly, we got that OMB stored temperatures longer retention time than warmer one.
