Abstract
A fluid lading clarifying apparatus and process is provided which utilizes an upright-positioned, fine mesh screen that separates an outer influent fluid lading containing chamber from an inner clarified effluent fluid receiving chamber, and which cooperates with an inside positioned transducer means to induce a continuous particulate removing action on the influent fluid lading and provide a clarified fluid that is continuously moved under capillary action and a slight gradient through the interstices of the screen into the effluent receiving chamber. Ultrasonic energy is used to agglomerate the particulate material, to maintain the screen in a clean condition and its interstices free from flow-blocking air bubbles and thereby assure a continuous flow of influent fluid into the effluent chamber.
Claims6
An improved method for clarifying a liquid lading effluent by removing contaminating particles therefrom which comprises, continuously introducing liquid effluent into an outer chamber, employing an upstanding screen mesh to provide a central inner influent chamber for receiving clarified liquid therein, maintaining the screen mesh wetted along both sides thereof, maintaining the liquid effluent at about the viscosity of water at room temperature;
- applying ultrasonic energy within surrounding liquid closely adjacent to and along substantially the full extent of the screen mesh in such a parallel manner as to prevent the forming of a liquid meniscus and the effective forming of air bubbles within the screen mesh, to retain and agglomerate larger contaminant particles within the outer chamber in a spaced relation with respect to the screen mesh, and to continuously prevent clogging of the interstices of the screen mesh by smaller particles;
- all while moving clarified influent liquid solely under a slight pressure head and capillary action through the screen mesh into the inner chamber;
- and during the operation, removing agglomerated aggregate from the outer chamber and clarified influent liquid from the inner chamber in such a manner as to maintain the screen in a wetted condition along both sides thereof and to enable a continuous clarification of effluent liquid being introduced into the outer chamber.
