Abstract: An aquatic organism removal system includes a screen system and a return system. The screen system is adapted to separate aquatic organisms from cooling water entering a cooling water intake of a power producing facility and includes a screen intake and a screen exit downstream of the screen intake. The return system is connected to the screen exit and is adapted to receive the aquatic organisms and transfer the aquatic organisms safely to a source waterbody. When the cooling water and aquatic organisms enter the screen intake, the cooling water flows through the screen system and into the cooling water intake of a power producing facility and the aquatic organisms flow out the screen exit and into the return system.

Abstract: A coreless and spirally wound non-woven filter element is provided. The filter element includes at least one band of base media having a selected porosity and an interlay having a different porosity within at least one band of base media. The presence of the interlay in the filter element can create additional surface area within the contiguous construction of a filter element for filtration. This interlay can also create the ability to change direction of flow and to increase the deposition of specifically sized contaminants.

Abstract: A variety of improved hydroclone based fluid filtering systems are described. The hydroclones generally include a tank having an internal chamber and a filter (preferably a surface filter) that is positioned within the internal chamber. The filter defines a filtered fluid chamber within the internal chamber of the tank. The hydroclone may be operated such that a vortex of flowing fluid is formed between the chamber wall and the filter with the filter being located in the center of the vortex. With this arrangement, the filter acts as a cross-flow filter. In one aspect of the invention, the filter is a stepped filter. In another aspect of the invention, the filter is an surface filter, as for example, an electroformed metal surface filter. In some preferred embodiments, the openings in the filter are arranged as slots that extend substantially vertically so that they are oriented substantially perpendicular to the flow path of fluid flowing in the adjacent portion of the vortex. In another aspect of the invention, a circulating cleaning assembly is provided in the hydroclone region. The cleaning assembly is arranged to help clean the filter and is driven by the vortex of flowing fluid formed in the hydroclone region of the internal chamber. In yet another aspect of the invention, improved hydroclone intake structures are described. The described hydroclones may be used to filter water and other fluids in a wide variety of applications.

Abstract: A strainer is disclosed for filtering a flow stream passing therethrough, while reducing vortex shedding and related minimizing noise and vibration. The strainer includes an elongated member which defines a generally longitudinal axis, and having an opening at one end and a closed end at the opposite end. The opening has a greater dimension than the closed end. The elongated member includes a plurality of rows of apertures located between the opening and the closed end, with the apertures of each row being of generally equal dimension and located in a plane generally perpendicular to the longitudinal axis. The pluralities of rows of apertures are of distinct dimensions and form a semi-random pattern such that a flow stream passing therethrough causes distinct frequencies associated with each row, which frequencies generally reduce or cancel any pulsation resulting therefrom.

Abstract: A filter element (8), especially for use in backwash filtering systems, includes a filtering element through which a contaminated fluid flows in at least one direction (24). An intercepting device (62) has at least one rod-shaped permanent magnet or electromagnet (64) that at least partially removes magnetizable, especially ferritic portions from the fluid, before the fluid flows through the filtering element. A detaching device (68) removes the magnetizable portions from the intercepting device (62). The detaching device (68) is configured by a stripper ring (70) that travels along the rod-shaped magnet (64) and removes the portions retained by the intercepting device (62). When the filtering element is backwashed, the stripper ring (70), moved by the fluid flow, detaches the portions retained by the intercepting device (62). This filter element requires little construction space and allows for the automatic and energetically favorable removal of magnetizable, especially ferritic portions, when the filtering element is backwashed.
