Abstract: A method and apparatus for filtering a large volume fluid intake system using a modular immersed-filtration array that can be easily scaled for use in a wide variety of immersion filtering applications. The immersed-filtration array is composed of a plurality of individual filtration modules. Each filtration module has a mating end that allows the module to be coupled with a base unit or plenum via a common interface port located on the base unit. The array can be scaled in a plurality of ways.

Abstract: A backwashable filtration system comprises a plurality of filter cartridges each consisting of a column of stacked arcaded wafers disposed on a rigid geometric guide rod. The wafers have arcuate portions interconnected by straight portions to form a filtration portion. An upper and lower surface of the filtration portion has grooves disposed therein. The filtration portion is connected, via a plurality of tabs, to a mounting portion having an inner hexagonal cavity and a circular exterior. The inner hexagonal cavity is tightly toleranced to fit onto the rigid hexagonal guide rod so as to preclude rotation of the wafers about the rod. The relationship of the inner hexagonal cavity to the outer filtration portion ensures that the arcs will always align to each other and that the grooves on a top surface of a wafer will be offset from grooves on the bottom surface of an opposed wafer. Integral passages accommodate flow of filtrate to a clean chamber and accommodate the flow of backwash fluid through the stack.

Abstract: This invention is a filtration structure characterized by radial fluid flow through the wall of a cylindrical configuration that is established by a stack of serrated annular wafers which are constrained for slight axial movement with respect to each other, for the establishment of two conditions. In one condition, the wafers are axially compressed into snug contact under spring bias to establish a labyrinth of radial passages for fluid flow at a selected pressure. In the other condition, the axial compression of the disks is relieved and the disks are slightly separated by back flushing under an elevated pressure in such a way that cleansing is freely effected by reverse fluid flow.
