Underdrain flume plate

摘要

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.
