    Abstract: A filter assembly is provided that includes a hood, a drain manifold, a filter disposed between the hood and the drain manifold, a drainage space that is disposed between and in fluid communication with both the filter medium and the drain manifold, a check valve that is configured to permit air to escape but not to enter the drainage space so that a siphon can be established that draws additional fluid through the filter medium and into the drain manifold, the siphon continuing until air entering the hood disrupts the siphon, and a check valve cap that is configured to permit air to escape the check valve while preserving an air-filled void above the check valve when the filter assembly is submerged.

    Abstract: A large vault or tank receives the runoff water to be cleaned. There are one or more small tanks in the large tank (vault). Each small tank is inverted and receives water at its open lower end, from the large tank. The water entering the small tank rises, as the water level in the large tank rises, and flows upward through a filter. When the water level rises above the top of the filter it enters an outlet tube or pipe and then flows downwardly along the center-line of the filter. A float, a valve and a check valve may cause the system to function as a siphon and feed the filtered clean water to an outlet. Alternatively the siphoning effect will occur if the inside diameter of said outlet tube is small enough to form a partial vacuum.

    Abstract: A system for filtering liquids like cooling water and emergency cooling water in nuclear power stations and other industrial plants wherein a continuous circulation of a coolant or other liquid has to be secured. The system comprises a first filtering surface and a first filtrate space which is at least partially limited by the first filtering surface and at least one further filtering surface with a second filtrate space which is at least partially limited by a filtering surface. A filtrate outlet channel is connected to the first filtrate space and a siphon connects the filtrate spaces.

    Abstract: A filter centrifuge wherein a drum is rotated about a central axis at high speed so as to drive the liquid phase of a liquidsolid suspension out through a filter medium has a liquidcollecting chamber radially outside of the filter medium and provided with an outlet from which the liquid passing through the filter cake is expelled. A venturi pump in the drum has a suction side connected to the liquid-collecting compartment radially inwardly of the outlet thereof so as to produce a negativepressure gas head that serves to draw air and any remaining liquid through the filter cake after most of the liquid phase has been drawn off. In addition during operation of the filter centrifuge this venturi pump, which may be driven by the liquid phase as it issues from the compartment or by a fluid fed especially into the drum for this purpose, serves to maintain a predetermined negative pressure in the compartment under the filter medium.
