Abstract
Colloidal Gas Aphrons (CGA) are finding increasing application in wastewater processing, bioseparations, etc. This article describes effect of various operating conditions such as pH, power input, impeller location, surfactant type and its concentration and viscosity of liquid on half life of CGA generated. Further, effects of various additives like, polymer, enzyme, solvents, salt, etc. are also investigated. A procedure for predicting the drainage rate of CGA has been proposed.Keywords
