A support grid assembly for use in a vessel. The support grid assembly includes panels each including a first wall including a media-supporting screen and a second wall to be supported by the vessel wall inner surface. A manifold is coupled to the panels and is in hydraulic communication with vessel outlet. The manifold and the panels permit fluid to flow through the screen in each panel, through the panels, into the manifold, and through the manifold to the outlet of the vessel, as well as in the reverse direction. At least a portion of the first wall may slope downward toward the manifold, and at least a portion of the second wall may form a bottom surface that is curved to substantially conform to a curvature of the vessel wall inner surface. The panels may be arranged in a circular configuration extending radially from the manifold.

A screen assembly including at least upper and lower portions each with screen elements having different orientations. The upper portion includes a first plurality of screen elements and the lower portion includes a second plurality of screen elements. The upper and lower portions are coupled together to form a truncated conical arrangement. At least one screen element of the first plurality of screen elements has a different angular orientation relative to a plane that is perpendicular to the central longitudinal axis than at least one screen element of the second plurality of screen elements has relative to the plane. In some such embodiments, the screen elements of the second plurality of screen elements are each oriented to be in a respective plane that is substantially perpendicular to the central longitudinal axis. The screen assembly may be configured to separate a liquid component and a solid component from a slurry.

An adjustable nozzle assembly for a sieve box and a sieve box including same, including a support assembly and nozzles. A pair of elongated support members may be received through openings in support collars. Nozzles may be operatively connected to the collars. The support assembly, which may include collars and rods, are configured to provide at least one of lateral movement and rotational movement of the nozzles. At least one of the first elongated support member and the second elongated support member may be configured to move when coupled to the sieve box to adjust a spray angle of the nozzles. Pivoting of the one rod about the other rod adjusts the angle at which the nozzles are disposed. The rods may be externally threaded, and the collars may be internally threaded, such that when the rods are rotated, the collars translate laterally along the rods to move the nozzles.

A disconnection tool for disconnecting pipes which are connected. The disconnection tool is preferably a two piece cylinder with a leading edge and handles opposite the leading edge, and, can be positioned around a male end of a male pipe that is within a female end of a female pipe. The disconnection tool initially inserts into a clearance between the interior surface of the female end and the exterior surface of the male end while the pipes are connected. As the disconnection tool is further inserted, its leading edge contacts and disengages one or more locking members extending through the clearance thereby allowing the male pipe to be disconnected from the female pipe.

A method and apparatus for a backwash system for cleaning an underwater intake filter assembly. The backwash system includes an underwater tank coupled on one end to a source of compressed fluid and on the other end to the intake screen assembly. The backwash system includes a U-shaped release conduit that is adapted to release a predetermined quantity of fluid to the intake screen in order to clean the filter assembly of waterborne debris.
