ABSTRACT:
A process is described for filtration of fluids, particularly of beverages like beer, utilizing microfiltration membrane modules operated in alternating filtering cycles and cleansing cycles, in which the cleansing cycles are always carried out when the transmembrane pressure exceeds a pre-set pressure which has been set to equal to the optimum trans-membrane pressure for the particular fluid being filtered, based on an analysis of the fluid after it has been filtered. In beer filteration, this value is preferably set at 1.5 bar. The microfiltration facility is equipped with numerous MF modules, arrayed in series and parallel; with a device for cleansing the MF modules and a measuring device for recording trans-membrane pressure that is attached to a control device which, upon attaining the pre-set trans-membrane pressure, interrupts the filtering cycle and starts a cleansing cycle.
