Web1 de nov. de 2005 · To improve the mass transfer efficiency, the interfacial area and the liquid-side mass transfer coefficient have to be controlled closely. The objective of the present study is to evaluate the effect of surfactants on interfacial area and liquid-side mass transfer coefficient. WebHeaviside Theory (HST) based Concept: In oxic bioprocess engineering system in liquid culture transfer of oxygen from air to liquid has been measured by fast response steam sterilizable dissolved oxygen probe on line. In the measurement, the concept of flow of oxygen from higher concentration (heaviside) to lower concentration has been conceived.
