Abstract

The invention relates to a method and a device for reducing biofouling on membranes during the purification of an aqueous medium by way of pressure-driven membrane separation processes. Ingredients causing biofouling are removed from the aqueous medium to be purified by attachment thereof to sacrificial filters (3) that are arranged in the supply line (2) to the pressure-driven membrane separation installation (4).
