Abstract
A spacer for guiding flowing medium, especially in apparatus for filtering and separating flowing medium via reverse osmosis and ultrafiltration. The spacer has a central hole that essentially serves for the clamping together of a plurality of disk-like spacers. A filter element is disposed between each two spacers, with flowing medium flowing about both sides of the filter element. To reduce pressure loss in the flowing medium, a plurality of spaced-apart openings through which flowing medium passes are disposed about the central hole of the spacer.
