✦ Synopsis
A study on the clariÐcation of bakerÏs yeast suspension by Colloidal Gas Aphrons (CGA) employing a cationic surfactant, benzyl-dimethyl-hexadecylammonium chloride, is presented. The variables investigated were the CGA Ñowrate, air Ñowrate and the yeast concentration. A separation efficiency as high as 95% was achieved at the optimum conditions of air Ñowrate and feed concentration. The mechanism of particleÈbubble attachment was identiÐed and a simple model for the monolayer adsorption of yeast cells on the bubble surface derived.
