The micro-bubble technology in water is widely known and effectively used, but the fundamental mechanisms of the micro-bubble generation and characteristics are not clearly established. To better the understanding, extensive literature survey coupled with theoretical and experimental bubble size estimations and volumetric mass transfer rate calculations were carried out. Observed multitude of increase in the volumetric mass transfer rate is essentially due to the specific interfacial area rather than the liquid mass transfer co-efficient. This signifies the effectiveness of pressurized dissolution type over its counterparts. A second set of experiments were focussed on particle size analysis using Bluewave particle size analyzer. Measurements for bubble size distribution were made alongside two cases of surfactant addition, tween20 at concentrations of 10mM and 1mM. The effect of surfactant on bubble dynamics and stabilization is interpreted and the axial rise distance hence the rise velocity are computed for both experimental and theoretical data.
