A spacer element for guiding flowing medium, especially for apparatus for separating the medium by reverse osmosis and ultrafiltration, with a respective filter element being accommodated between each two essentially plate-like spacer elements, about which the medium flows. The spacer element comprises a plate member having a rim region in which is provided at least one passage for the flowing medium, with the plate member having two oppositely disposed plate-like surfaces, on at least one of which are disposed a plurality of raised bosses that project from the surface, with the filter element resting on the bosses, whereby the filter element is in the form of a diaphragm pad, with the medium flowing on both sides thereof.
