Abstract: A device for the treatment of an influent with a porous media. The influent passes radially through the porous media and into an internal volume of the device. The treated influent then passes through an open check valve in the internal volume, and then to downstream equipment. During a backwash operation, a backwash fluid is passed into the internal volume of the device in a direction to close the check valve. The blocked path in the internal volume of the device causes the backwash fluid to pass radially outwardly into the porous media and fluidize the same.

Abstract: Fluted filter media includes filter material having a plurality of flutes formed therein having alternating ends of adjacent flutes closed to force fluid through filter material. A first embodiment of the filter media includes tapered flutes which have the open ends of the flutes larger in cross-section than the closed flutes, wherein the upstream open flutes converge toward the downstream end and the upstream closed end flutes diverge toward the downstream end. A second embodiment includes filter media which is asymmetric formed with dissimilar upstream and downstream flute cross-sections with larger flute openings to the upstream side of the filter. A third embodiment includes filter media with an upstream edge crushed to improve flow at the upstream edge. A fourth embodiment includes filter media with the upstream sealing material recessed from the upstream edge for reducing effects from blockages at the upstream edge of the filter.

Abstract: Prior art washer designs have segmented radial ducts feeding the filter valve which collect the filtrate emerging from the longitudinal ducts. Because these ducts are radial, the volume at the periphery is much greater than at the valve entry which creates undesirable conditions such as a large volume where air can escape from the filtrate forming a pocket which will reduce the effectiveness of the vacuum and promote non-uniformity in filtrate velocity. The present invention incorporates a baffle in the radial duct which reduces the volume at the periphery and maintains a uniform cross-sectional area for the filtrate to reach the valve. This maintains a constant filtrate velocity and prevents the possibility of the formation of an air pocket.

Abstract: Disclosed is a mixer-distributor-collector apparatus for use between beds of solid particles in a fluid-solid contacting vessel. The apparatus includes a solids retaining screen, fluid deflector, passageway, fluid distributor, and flow manipulator. The flow manipulator is a device such as a honeycomb, porous solid, perforated plate, screen, or grid having an open area greater than the open area of the fluid distributor and is located below and spaced apart from the fluid distributor. The apparatus improves the fluid flow characteristics by minimizing or eliminating fluid velocity jets and/or other turbulence which can disturb the downstream particle bed. In an exemplary application, the invention finds use in simulated moving bed (SMB) adsorptive separation processes.

Abstract: A filter underdrain system and a method for measuring the water flow through the underdrain filter system. The apparatus includes panel members assembled to form a perforate grid on the filter base structure of an underdrain block. The panels are generally rectangular and have an upper and lower surface. Multiple apertures are provided in the panel member. The number and/or size of the apertures are dimensioned to prevent the egress of filter media and to obtain substantially uniform backwash flow in the underdrain thereby reducing or eliminating water maldistribution.

Abstract: A whirlpool bath has a combination suction fixture and disposable filter. The suction fixture is a plastic semi-cylindrical housing attachable to the tub. A removable faceplate is reinforced and resistant to body and hair entrapment. The disposable filter is fibrous having a porous core, wherein the porous core has a series of holes and/or slots graduating in size from small at the outlet end to large at the remote end. The filter, sloped floor of the housing and drain slots provide for low water retention during shutdown. A safety/sanitation port on the outlet port creates cavitation if the whirlpool bath is operated without the disposable filter. The preferred embodiment removable faceplate is attached to the housing via a magnet and a peripheral ledge providing a pop off design. The preferred embodiment filter also has a pop off design.

Abstract: An agricultural or industrial water filter comprises a spin plate, a flow distributing sleeve, and a cone basin. The spin plate includes fluid passageways disposed at a 20 degree angle relative to the axis of the filter. The flow distributing sleeve is disposed in between the screen and the filter chamber. The screen may be oversize with a screen area that is a multiple of the screen area of a standard screen. The sleeve comprises a plurality of axial slots which are more narrow at the proximal side and wider at the distal side. The end cap is coupled to a bottom of the filter chamber and disposed adjacent to a bottom of the screen. The end cap comprises a cone coupled to the top of a basin. The cone extends upwardly into the space within the screen. A narrow annulus with a small cross-sectional area is formed between the bottom edge of the cone and the top of the basin. The basin includes a flush tube to flush out particles collected in the basin and to cause a high velocity flow through the annulus.
