Apparatus for desalination and purification of water by reverse osmosis

An apparatus for the desalination and purification of water by reverse osis and ultrafiltration. The apparatus includes dish-like carrier plates and water guide plates held between two end plates and alternately stacked one above the other. The apparatus also includes annular diaphragms which lie between respective carrier plates and guide plates and are each backed by a filter layer, so that in use untreated water flows over the diaphragms in the radial direction on the side opposite the filter layer, and permeate or water suitable for industrial use is drawn off at the side backed by the filter layer. The stack of end plates, carrier plates, and guide plates is clamped or held together at the periphery and has a continuous central aperture for the introduction of the untreated water. The carrier plates sealingly engage one another by means of thickened marginal portions lying radially beyond the edges of the guide plates. The marginal portions have continuous bores which are aligned with one another and with bores in the end plates, and provide an outlet for the permeate. The bores, toward the middle of the plates, communicate with the filter layers of the diaphragms by means of gaps 34 produced by reduced thicknesses of the marginal portions of the carrier plates.
