Characteristics and Equation of Filtration of O/W Emulsion with Glass-Fiber Filter Paper under Constant Pressure

Abstract

The phase-separation needs of a liquid-liquid extraction operation with emulsification were studied experimentally in the absence of mass transfer.
Objects of this study were to investigate the characteristics of filtration, to search for an excellent filter medium, to clarify the filtration mechanism and to obtain the equation of filtration in the case where emulsion is filtered with glass-fiber filter paper under constant pressure.
It was experimentally confirmed that filter paper made of glass fiber is superior to that of cellulose for filtration of O/W emulsion. There is a critical filtration pressure which is the maximum pressure at which the emulsion can be filtered clearly. The analytically obtained equation of filtration is valid for O/W emulsion with glass fiber filter paper.
