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.

Settler with a settler plate that includes a hollow support

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.

Nozzle for a fluid

Settler plate

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.

Method and apparatus for helical flow in a header conduit

Apparatus for simultaneously taking up and paying out first and second ends of respective first and second cables is provided for traversing a carriage in a clarifier basin. Each of the cables has the same active length. A reel has a cylindrical drum, opposite ends, and a pair of cable retainers. One of the retainers is adjacent to one of the opposite ends and on a first diametric side of the drum. The other of the retainers is adjacent to the other of the opposite ends and on a second or opposite diametric side of the drum. The second diametric side is opposite to the first diametric side. In a method of the invention, the first end of the first cable is secured to the one retainer the drum is adapted to receive all of the active length of the first cable in one layer thereon or all of said active length of the second cable in one layer thereon or a wound portion of the active length of each of the cables in one layer thereon, with the wound one layer portions sharing the drum in side-by-side relation. The method winds the active length of the first cable completely onto the drum and then the second cable is secured to the other retainer. The drum is then rotated to pay out the first cable and take up the second cable and traverse the carriage in the basin.

Apparatus and method for controlling the positioning of substrates for supporting bacteria in a waste treatment container use an aerator manifold which supplies bubbles of gas to the container from adjacent the bottom of the container. A hollow open mesh tube forms the substrate and is extended under the manifold to define a leg extending upwardly from each side of the manifold. A buoyant array piece is secured to each such end and urges the tube upwardly toward the upper surface of the waste. The bubbles establish a rolling upward flow of the waste in the container between the legs of the tube, which urges the buoyant array pieces apart both during the treatment operation and during draining of the container. Such urging during draining urges the buoyant array pieces away from the manifold, which pieces carry the ends of the tube away from the manifold as they become located lower in the basin. Such urging avoids tangling of the tubes with the manifold and facilitates more efficient cleaning of the manifold. Units of the array pieces are formed by clipping the array pieces together in various configurations, which additionally assists in keeping the array pieces and tubes away from the manifold.
