摘要： A filtration system having an underdrain block and an underdrain wall adaptor. The underdrain wall adaptor includes a vertical end and horizontal base. The vertical end extends from a top wall to a bottom wall of an underdrain block and mates with an end portion of an underdrain block to secure the underdrain wall adaptor to the underdrain block. The horizontal base extends from the vertical end. The invention also includes a method of installing an underdrain wall adaptor. The underdrain wall adaptor controls air and water passage between the flume and the underdrain.

摘要： An underdrain system for transferring forces and directing flow includes at least one underdrain block having a top wall, a bottom wall, and two side walls connecting the top wall to the bottom wall to define a block interior. An insert is disposed in the interior of the underdrain block. The insert includes force-transmitting buttresses spaced along an exterior of the insert that contacts the two side walls of the underdrain block and act to transfer downward forces acting on the top wall of the underdrain block and internal fluid forces acting on the insert to the side walls of the underdrain block. The force-transmitting buttresses can also direct hydraulic flow.

摘要： A filter system having a filter media retainer seal includes: at least one underdrain block having a top wall, a bottom wall, and a pair of side walls extending between the top wall and the bottom wall; a filter media retainer mounted onto the top wall of the at least one underdrain block; and at least one rib positioned between the underdrain block and the filter media retainer. The at least one rib forms a seal between the underdrain block and the filter media retainer, and prevents filter media from entering the underdrain block. The at least one rib can be monolithically formed to the at least one underdrain block. Alternatively, the at least one rib is monolithically formed to the filter media retainer. The rib is crushable and/or it bites into a surface on the adjoining part to reduce or eliminate the need for a separate sealant.

摘要： A media retainer assembly for retaining filter media in a filter assembly includes a top plate for supporting the filter media, the top plate having a top surface, a bottom surface and a plurality of openings extending therethrough; a bottom plate having a top surface and a plurality of openings extending therethrough; and scouring media, the scouring media being adapted to abrade the surfaces of the top and bottom plates. The top plate is connected to the bottom plate such that the top surface of the bottom plate is spaced from the bottom surface of the top plate to define at least one chamber between the top plate and the bottom plate. The top surface of the top plate is in fluid communication with the chamber via the openings in the top plate. The scouring media is supported by the bottom plate within the at least one chamber.

摘要： A cover for a liquid containment apparatus includes: a platform having a top surface, a first end, a second end opposite the first end, and two opposing sides that extend between the first and second ends. The cover also includes: a front wall extending down from the first end of the platform; a back wall extending down from the second end of the platform; side walls extending down from the opposing sides of the platform; and engagement members extending out from a bottom of the side walls in a lateral direction from the platform and which are configured to engage a surface of a substrate. The platform includes a plurality of holes, and the side walls include a plurality of notches that form a weir for distributing liquids. A liquid containment system is also included.

摘要： A filter media retainer has a plate having a first end wall, a second end wall, and a pair of longitudinal sidewalls connected to opposing sides of the first end wall and the second end wall. The plate has a top surface opposite a bottom surface. A plurality of hopper-shaped compartments are formed on the top surface and have a first sloped wall and a second sloped wall angled toward the first sloped wall in a direction from the top surface toward the bottom surface. The plate further has a top sidewall on the top surface of the plate separating adjacent hopper-shaped compartments from each other. The plate further has at least one first slot extending through at least one of the first sloped wall and the second sloped wall, and at least one second slot extending through the top sidewall.
