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 connecte...
