Abstract:
A filter system comprising:a chamber having a first end and a second end; inlet hydraulic conduit means connected to the first end of said chamber for admitting liquid to be filtered; a plurality of filter elements within said chamber, each of said filter elements having a first rod-shaped end and a second rod-shaped end projecting from said filter element; a first structure which includes a first manifold near the first end of the chamber, said first manifold having a chamber connecting end that allows liquid to flow in or out of the first manifold, and an element connecting end with means to couple the first rod-shaped end of each of the filter elements to the first manifold; a second structure which includes a second manifold near the second end of said chamber, said second manifold having a chamber connecting end that allows liquid to flow in or out of the second manifold, and an element connecting end with means to couple the second rod-shaped end of each of said filter elements to said second manifold; a first hydraulic means having a first end coupled to the chamber connecting end of the first manifold for conducting liquid to and from the first manifold, and a second end connected to the chamber and extending externally therethrough; a second hydraulic means having a first end coupled to the chamber connecting end of the second manifold for conducting liquid to and from the second manifold, and a second end connected to the chamber and extending externally therethrough; means carried by said chamber for supporting the plurality of filter elements, said supporting means co-acting with the first and second hydraulic conduit means to maintain the filter elements in a fixed predetermined relation within the chamber and permitting ready removal of said elements from the chamber as a unit; and a flow control device located between the first rod-shaped end and the second rod-shaped end of each of the plurality of filter elements.
