摘要：This article discusses and analyses the latest concepts of depositions of colloidal, suspended, and organic substances on membranes. The existing models of concentration polarization in apparatuses of various design are described, the influence of generated deposits on decrease in efficiency and selectivity of membranes is estimated. It is demonstrated that the transient flow rate prevents concentrating of particles and organic molecules near membrane surface providing their detachment. However, despite favorable influence of hydrodynamic conditions on membrane operation, they are not sufficiently studied in order to control fouling which is also influenced by channel geometry and resistance, as well as adhesive and adsorptive properties of membrane material.
