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.

The disclosure relates to a system and method for cleaning filters, such as membrane filters. More particularly, a method and system are disclosed for retaining a plurality of small particulates, preferably in the shape of beads, which contact sludge or other despots on the membrane filters to remove unwanted debris that would otherwise form on the cleaning filters. In various embodiments, the plurality of small particulates are retained in a permeable enclosure formed of wedgewire.

An improved cascade aerator is disclosed, comprising a trough having a low profile slope, whereby the trough is divided into a plurality of adjacent longitudinal channels. In one embodiment, a plurality of low head baffles are mounted in spaced relationship and transversely of the longitudinal channels and are spaced apart from the floor of the trough.

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.
