US Classification:

210541, 29428

Abstract:

An underdrain flume plate for use in a filter including at least one central opening having an upstanding flange to interface with a cut-out in an underdrain lateral to form a passageway for connecting the lateral to the flume. The flume plate may also include at least one raised channel at each end of the plate with a solid or cut-away top surface, and/or holes and/or slots for connection of the flume plate to anchor rods and may be configured to overlap one another when placed side by side. The present invention also includes a method of installing underdrain laterals in a filter, including arranging a grid of anchor rods on a filter floor such that anchor rods are provided on both sides of the flume, and providing at least one underdrain flume plate adapted for attachment to the anchor rods such that the flume plate covers the flume.

Assignee:

Xylem Water Solutions Zelienople LLC - Zelienople PA

International Classification:

B01D 35/30

US Classification:

210232

Abstract:

A filter system for filtering a liquid containing particles including a single media retainer plate having a top and bottom surface, and defining at least one hopper-shaped compartment having a sloped wall defining a slot spanning the top and bottom surfaces is disclosed. The plate also includes at least one baffle extending from the bottom surface and filter media disposed on the top surface. During a filtering operation of the filter system, the filter media captures the particles, such as dirt, from the liquid as the liquid passes through the filter media to an underdrain system. During a backwash operation of the filter system, the baffle is adapted to direct a backwash fluid in a vertical direction through the slot so that the backwash fluid actuates the filter media to scour the top surface of the plate and prevent the build-up of biological scaling on the plate.

US Classification:

210483, 29428

Abstract:

An underdrain filter block for use in draining and backwashing a filtering media in a filter bed includes a top wall, a pair of side walls extending from the top wall, a bottom wall extending between the pair of side walls, and a transverse wall extending from one of the pair of side walls to the other of the pair of side walls. The top wall, the pair of side walls, and the bottom wall define an upper portion and a lower portion. The lower portion includes a grout chamber positioned between the bottom wall and the transverse wall and at least one of the bottom wall and said side walls contains an opening.

US Classification:

210275, 210293, 210263

Abstract:

A filter system for filtering particles from a liquid includes an underdrain assembly having an underdrain defining at least one underdrain chamber and a media retainer assembly. The media retainer assembly includes an upper filter media retainer plate defining a plurality of hopper-shaped cavities and a lower filter media retainer plate defining a plurality of hopper-shaped cavities corresponding to the plurality of hopper-shaped cavities on the upper plate. The plates are in a nested arrangement such that the hopper-shaped cavities on the upper plate are in alignment with the corresponding plurality of hopper-shaped cavities on the lower plate to define a plurality of passages therebetween and allow for the passage of the liquid while preventing the passage of a filter media. During a backwash operation, the upper and lower plates are relatively moveable such that the backwash fluid releases any particles lodged in the passages between the plates.
