Abstract
An apparatus for filtering and separating flow medium by reverse osmosis, ultrafiltration, and microfiltration. A plurality of essentially sheet-like filter elements are disposed next to, and spaced from, one another so a to form flow chambers for the flow medium. Filtrate that is produced is withdrawn at the end face of at least one hole formed in a filter element and disposed at essentially right angles to the planar surface thereof. A plurality of sheet-like, self-supporting filter element carriers that are successively arranged have disposed essentially laminarly thereon the filter elements, with the filter element carriers being spaced from one another at such a distance that there is formed between each two facing filter elements one of the flow chambers. Disposed in each flow chamber, between two facing filter elements, is a disk that imparts turbulence to flow medium in the flow chamber.
