Abstract

Abstract A simple model for the filtration of a destabilized colloidal suspension is proposed. It takes into account the effect of flocculation on the properties of the deposited layer. It is shown that the cake permeability is a function of the quantity ω t R, where ω is the flocculation rate (collision frequency) and t R is the residence time defined by the time from which the particle enters the membrane channel to the time that it attaches onto the membrane surface.
