Abstract
The present invention is a composite filter for use with recycling gray water. The filter is comprised of a housing containing a series of filters, a first depth filter, preferably made of cellulose fibers for removing particles and turbidity causing materials, a second depth filter, preferably made of cellulose and diatomaceous earth for removing additional particles and turbidity causing materials, an organics filter, preferably a carbon filter to remove organic material and an ion exchange material to remove dissolved ionic species such as salts, acids and the like.

1) A composite filter comprising a housing having a first end and a second end, each end being sealed in a liquid-tight manner by a first and a second endcap respectively, the first endcap having an inlet from a gray water source, the second endcap having an outlet from the housing, a first filter stage arranged in the housing adjacent and downstream of the inlet and a second stage arranged downstream of the first stage and adjacent the outlet, the first stage comprising a two or more depth filters in series followed by an organics filter, the first stage being arranged in a liquid-tight manner such that gray water entering the inlet must flow through the first stage before reaching the second stage and the second stage comprising an ion exchange media for the removal of dissolved ionic species from the gray water.
