Abstract

Mathematical models of batch operation ultrafiltration plants with retentate recirculation and separate venting of the solution from the membrane module outlet are considered. Two variants of process realization with retentate return to the tank with initial solution, or its return to the apparatus inlet are analyzed. It has been shown, that both schemes enable to obtain the final product of the same concentration, but the scheme with retentate return to the module inlet runs more risk of membrane pollution.
