Abstract
A manifold mounted liquid filtration system including a disposable filter cartridge having first and second radial flow filtration stages containing filtration media of uniform porosity. A first stage includes a pair of annular, concentrically mounted, fibrous sediment and cast carbonaceous filter media. A second stage includes an annular cast carbonaceous filter media. Porous stage separators sequentially direct liquid flow into cavity spaces between the sidewalls of each stage and a liquid impermeable housing where the flow is radially re-directed inward to a center outlet bore. The first stage filters suspended sediments, lead and other heavy metals. The second stage removes suspended bacteria, parasites volatile organic contaminants, herbicides, pesticides, industrial and agricultural contaminants, and the like. Various cartridge constructions having alternative O'ring sealed end caps and internal arrangements of stage separators are disclosed. Also disclosed is a disposable manifold cover/filter assembly.
