Abstract:
A system for removing sediment from water is disclosed. The exemplary embodiments described herein disclose a system comprising a filter chamber, having a deck positioned inside to divide it into an upper chamber and a lower chamber. The deck may have a plurality of holes to hold filtration elements and also may have a ridge or a skirt or both. An inlet line may be tangentially connected to the filter chamber and introduce influent liquid into the filter chamber below the deck and outside of the skirt.
Abstract:
A fluid filter system with cartridge filters housed in a tank in which each cartridge filter has a lift tube positioned concentrically within each cartridge filter. The lift tubes extend from a support plate, which divides the tank into a raw fluid chamber and a processed fluid chamber, toward a tank cover. The lift tubes have inlet ports proximate to the tank cover so that the fluid surface in the tank is maintained at or near an upper end of the cartridge filters. This configuration enables the lift tubes to exhaust excess air in the tank through the lift tubes and out of the filter system through outlet ports in the processed fluid chamber. By exhausting air from the filter system, the capacity of the system is not compromised by the air and the expected life of the cartridge filters is not reduced.

Abstract:
The invention relate to a backflush filter, in particular for water filtration. The cleaning device for the backflush filter comprises a flushing arm (25), connected to the upper perforated plate (21) of a filter set (20) and a second flushing arm (35), connected to the lower perforated plate (31). The flushing arms (25, 35) each comprise a hollow flushing member (27, 37) and also a sealing member (28, 38). The flushing arms (27, 37) and sealing members (28, 38) are arranged at an offset of 180 DEG to each other so that the cleaning device may be used for time-shifted and counter-flow backflushing. The filter element (22') is connected to ambient pressure by means of the flushing member (27) and the outlet valve (50). The upper input end (24') of the filter element (22') is then sealed by means of the sealing member (28). At a later point in time the upper input end (24') is connected to ambient pressure by means of the flushing member (27). In the case of electrical drive the drive energy may be provided by means of a solar panel (57).
Abstract:
An apparatus and method for filtration of solid particles and organisms from a flowing liquid and for cleaning filter elements while maintaining a positive flow of filtered liquid from the system while so cleaning. Turbulent liquid flow, ultraviolet radiation and system pressure are disclosed aspects of the apparatus and method.
Abstract:
A filtering apparatus (10) includes a container barrel (20) and a detachable filtering unit (40) detachably mounted inside the container barrel (20). The detachable filtering unit (40) has a top lid (41), a bottom lid (42), and a plurality of filter cores (43) sandwiched between the top lid (41) and the bottom lid (42). Because the filtering apparatus (10) has the detachable filtering unit (40) that can be totally taken out from the container barrel (20), the works of replacing the filter cores (43) and washing the container barrel (20), especially the bottom portion of the container barrel (20), can be conveniently done.
