摘要： The present invention is directed to a plate settler cover that prevents algae growth, prevents contamination from organic material, and provides structural support for a user who is standing or walking on the plate settler system. The plate settler covers can either float directly on standing water present in the system or may be structurally supported such that the plate cover is positioned above the surface of the water.

摘要： A nozzle is provided for a header conduit. The nozzle includes an inlet that is resistant to clogs caused by flat materials covering the inlet. The inlet generally includes multiple pathways to an elongated passageway through which waste liquid and sludge (“waste”) are guided and enter the header conduit. In one embodiment, the elongated passageway is oriented to guide the waste along a path that is tangential to at least the inner surface of the header conduit which such incoming waste first contacts. When the conduit has an inner surface of circular cross-section, the passageway may optionally be elongated enough that the incoming waste enters the header conduit along a path tangential to the circular surface. To better assure axial flow of the waste in the conduit to an outlet, in one embodiment the passageway provides both the tangential flow and is at an acute angle to the longitudinal axis of the conduit. The incoming waste is thereby provided with an axial component. In this manner, the passageway assures that the energy and momentum of the incoming waste is helical in direction. The waste previously admitted into the header conduit is urged by the newly entering waste to continue to flow helically in the conduit. The passageways are provided at spaced intervals along the length of the conduit to collect sludge from a wide area of the bottom of the basin. Because of the tangential orientation of each of the passageways and the resulting initial tangential flow of the incoming waste, the waste incoming from each of those multiple passageways reinforces the existing helical flow of waste in the conduit.

摘要： The present disclosure relates to settler plates for a plate settler. The settler plates generally include a hollow support with a hollow interior to receive clarified liquid from a flow channel between adjacent settler plates. An orifice is formed through the hollow support to direct clarified liquid from the flow channel into the hollow interior. The orifice can be positioned such that clarified liquid can flow upwardly out of the flow channel and downwardly through the orifice into the hollow interior. The hollow support can be integrally formed with the settler plate. For example, the hollow support can be formed by bending a tab extending from an end of the settler plate. The tab can be bent into a hollow support with a cross section that is generally polygonal.

摘要： An underdrain apparatus and a method for manufacturing such apparatus are provided. The underdrain apparatus can be extruded in long sections as a unitary part. The underdrain apparatus may be extruded in various sizes, shapes, and materials. Further, the underdrain apparatus may include a passageway for transporting water to and from the filter media and/or air to the filter media. In some embodiments, apertures are formed in the underdrain apparatus during an extrusion process to provide a path between the passageway and the filter media.

摘要： Apparatus and methods provide individual blades driven by drives configured to reduce a tendency of sludge to be moved in an undesired return direction. Drive configurations apply “pull” and “pull” forces that only pull on tensile structures, avoiding a need in actual commercial practice for use of extra structural drive members having high resistance to both tension and compressive forces exerted parallel to a sludge movement direction. Each of two separate tensile structures carries one blade, or a separate set of blades, with blade(s) of one structure adjacent to, and alternating with, blade(s) of the other structure. Embodiments move sludge from a corner of a basin and across a floor of the basin. The reduced tendency of sludge movement in the return direction results from moving one tensile structure and blade(s) in the sludge movement direction as the other tensile structure and adjacent opposed blade(s) move in the return direction.
