Abstract: Apparatuses and methods are described herein. An example embodiment may include a balanced diagonal sludge removal assembly configured for use in a basin, the balanced diagonal sludge removal assembly including a discharge pipe, a collection pipe configured to slideably receive the discharge pipe, one or more header pipes extending from the collection pipe to define a first sludge communication path between the one or more header pipes and the collection pipe, and one or more balancing diagonals extending between the collection pipe and the one or more header pipes to define a second sludge communication path between the one or more header pipes and the collection pipe, wherein the one or more balancing diagonals balance flow distribution throughout the one or more header pipes.

Abstract: Various embodiments of the present invention are directed to a plate settler comprising: a plurality of plates, each plate defining a first end, a second end, and a settling surface there between; a plurality of angular support members extending from and structurally supporting the first ends of respective ones of the plurality of plates, each angular support member defining a first lateral flow encouraging surface and a second lateral flow encouraging surface; and a plurality of headloss control gaps defined by the plurality of angular support members. The first lateral flow encouraging surface of each angular support member may combine with the second lateral flow encouraging surface of an adjacent angular support member to define a generally v-shaped lateral flow channel.

Abstract: A lamella panel module is formed from extruded PVC side rails and a plastic plate member secured to the opposing side panels. Each side rail is formed with receiver mounts defining recesses for the mounting of the lamella plates. The plates are preferably affixed to the receiver mounts by adhesives to establish a structurally stable panel module. Each side rail has fore-and-aft opposing mating flanges that prevent horizontal movement of the modules, but allow generally vertical movement to enable any module to be removed from the assembly and replaced. The frame of the lamella separator assembly is formed with a support ledge on the opposing lateral sides of the frame to support a walking grid therebetween. The supported walking grid does not interfere with the flow of clarified water into the collection troughs supported on a vertical member projecting above the support ledge and allows cleaning of the plates.
