Abstract
A study on the clarification of baker's yeast suspension by Colloidal Gas Aphrons (CGA) employing a cationic surfactant, benzyl-dimethyl-hex adecyl-ammonium chloride, is presented. The variables investigated wer e the CGA flowrate, air flowrate and the yeast concentration. A separa tion efficiency as high as 95% was achieved at the optimum conditions of air flowrate and feed concentration. The mechanism of particle-bubb le attachment was identified and a simple model for the monolayer adso rption of yeast cells on the bubble surface derived. (C) 1998 SCI.
