Abstract
In a process and an apparatus for separating solid particles from aqueous suspensions by filtration with continuous cleaning of the filter surfaces, a horizontal introduction of the suspensions is to be made possible even under restricted spatial conditions. According to the invention this is achieved in that the suspension is set in rotation in a plane perpendicular to gravity, a water mist forming under the action of gravity, which water mist is passed over a porous, cylindrical filter surface (5) and in that the solid particles are enriched in the rotating water mist, while the purified water passes through the porous filter surface (5) and is conducted away from there. The separation forces are then applied by utilisation of capillary effects, the sieve device being preferably composed of a double-action filter element, which has an increased development of adhesion forces. The filter element has finely configured capillaries which pass through the sieve body and thus enable solids separation. <IMAGE>
