Abstract:
A multi-faceted intake filter for an aquarium includes a top surface portion, a bottom surface portion and a plurality of side surface portions that collectively define a filter body is formed from a compressible foam. The intake filter also includes a bore that extends along a longitudinal axis of the filter body. The bore includes a first end exposed at the top surface portion that leads to a second end which terminates prior to the bottom surface portion. The bore is designed to receive an intake portion of an aquarium filter tube. Preferably, the bore is off-set from a central axis of the filter body. The off-set bore allows the intake filter to be placed in a wide range of aquarium configurations, with at least one of the side surface portions abutting a wall of the aquarium.
Abstract:
Filtervorrichtung für das Wasser von Gartenteichen oder Aquarien mit einem Gehäuse (2), einem Wassereinlass (4), einem Wasserauslass (5) und wenigstens einem mittels einer Betätigungsvorrichtung im Gehäuse (2) komprimierbaren Filter (9), welcher im Strömungsweg zwischen Wasserein- und Wasserauslass (4, 5) angeordnet ist und zumindest jeweils eine Wasseranström- und eine Wasserabströmoberfläche aufweist, wobei die Wasserabströmoberfläche wenigstens einen Kanal (14) ausbildet, in dem Wasser in Richtung des Wasserauslasses (5) transportierbar ist.
Abstract:
A filter media backwash removal method and device for transporting backwash fluid and solids away from re-entering a housing containing circulating filter media.
Abstract:
The invention relates to a filter unit (1, 19) comprising: at least one spacer fabric (3) which comprises a first and a second cover layer (4; 5), each of which comprises a plurality of openings (6) that are delimited by edge regions (7). Threads (8) extend from the edge regions (7) of the first cover layer (4) to the edge regions (7) of the second cover layer (5), and the at least one spacer fabric is rolled, twisted, and/or compressed in at least one section.
Abstract:
A filter (2) comprising a body (4), an inlet (6) for a liquid passing into the body (4), an outlet (8) for the liquid passing out of the body (4), and a foam material (10) in the body (4) for filtering the liquid as the liquid passes through the body (4) and also for absorbing water in the liquid.
Abstract:
A filter apparatus connected a container, where the container includes a container neck and is filled with a filling material. The filter apparatus includes a filtrate riser tube in the container, which extends from the base region of the container to the container neck, a container connector head, which is fastened to the container neck and defines passages connected to a liquid inlet line and an inlet filter, and a connector unit with a sealing piston in the connector unit, which is arranged so as to be lowerable to connect the liquid inlet line to the filter material in the container and the filtrate riser tube to the filtrate outlet line.
Abstract:
A stormwater treatment system includes water treatment media that defines a helical flow path within a conduit. The water treatment media may include a plurality of helical water treatment media components that are constructed and arranged to seal against an inside surface of the conduit. The individual helical water treatment media components may be installed in situ within the conduit when the conduit is positioned within a chamber having an access opening, and periodically removed and replaced by passing the components to the access opening. The components further may have a flexible frame, which allows the water treatment media to dynamically adjust to swelling of the filtration media and other forces that may occur during use. The performance of the system may be adjusted by adjusting the helical pitch of the helical water treatment media components.

A filter media backwash removal method and device for transporting backwash fluid and solids away from re-entering a housing containing circulating filter media.
Abstract:
An apparatus and method for filtering fluids with a multi-material filter media. Multi-component fibers where two or more materials are used in the same fiber to achieve desired physical characteristics, such as specific gravity, resilience, chemical resistance, stiffness and fiber diameter. Based on the particular application and fluid to be filtered, component materials provide desired performance characteristics such as specific particle size and/or specific pollutant removal capabilities and desired backwash cleaning characteristics.
