Abstract
A showerhead system with internal filtration media includes a fluid-tight pressure housing having a fluid inlet and a fluid outlet, the outlet substantially co-axial with the inlet, the housing having a substantially cylindrical internal surface. The system further includes several porous radial disks axially disposed internally to the pressure housing and having circumferential edges in integral communication with the internal cylindrical surface of the pressure housing. The system also include filtration media positional within regions defined between the porous disks. The system additionally includes at least one rigid radial disk axially disposed within the axial distribution of the plurality of porous disks, the rigid disk including groups of apertures. The rigid disk may or may not have an integral securement to the internal cylindrical surface of the pressure housing such that its axial position, within the system, is defined by filtration media packed on either side of it. As such, water is able to pass both through apertures in the rigid disk and across an annular region between the circumference of the rigid disk and the internal diameter of the internal surface of the pressure housing. Water flows of enhanced general turbulence are obtained.
