    Abstract: A filter cartridge including a frame that is formed of one or more fluid conductive members and has a fluid outlet and a plurality of spaced inlets; and a flexible fabric material that allows the flow of water therethrough, the flexible fabric material being connected to the frame in a manner defining an internal zone, whereby substantially all fluid entering the internal zone from an opposite side of the flexible fabric material passes therethrough; wherein, upon connection of the fluid outlet to a fluid intake system, fluid is drawn through the flexible fabric material into the internal zone, thereby filtering the fluid, and filtered fluid is drawn through the plurality of spaced inlets and passes to the fluid outlet for delivery into the fluid intake system. A system and method for filtering fluid intake are disclosed.

    Abstract: An embedded geometrically variable filter underdrain header and a method for constructing such a filter. Often the variation is a decrease in cross section along the header from the backwash media source, which avoids a pressure loss as liquid is diverted to the laterals along the header. The header is formed inside a filter underdrain basin and is embedded in the basin. The method for constructing the basin and header includes providing a mold for the basin and the header and filling the molds with concrete by pouring concrete into the area between the interior of the mold for the basin and the exterior of the mold for the header. After the concrete cures, the mold for the basin may or may not be removed, while the mold for the header is kept in place.

    Abstract: A filter underdrain system and a method for measuring the water flow through the underdrain filter system. The apparatus includes panel members assembled to form a perforate grid on the filter base structure of an underdrain block. The panels are generally rectangular and have an upper and lower surface. Multiple apertures are provided in the panel member. The number and/or size of the apertures are dimensioned to prevent the egress of filter media and to obtain substantially uniform backwash flow in the underdrain thereby reducing or eliminating water maldistribution.

    Abstract: A fluid control device includes a perforated tubular member and a first and second wrapper. The tubular member is disposed along an axial length of a separator element and includes a first end, a second end, and an outer surface. A flow outlet is disposed at the first end of the tubular member. The first wrapper is disposed on a first portion of the outer surface of the tubular member adjacent the flow outlet. The second wrapper is disposed on a second portion of the outer surface of the tubular member. The first and second wrappers provide different resistances to fluid flow. A portion of the outer surface of the tubular member adjacent the second end is free from wrapping.
