An improved waste treatment system and improved waste treatment system components are provided. In a preferred form, a waste stream is initially separated into primarily solid and primarily liquid components, and the liquids are then fed to a filter assembly. The filter assembly includes a pair of filter elements, and the flow is introduced into the filter assembly at a location between the filter elements. During a filtering operation, the liquid is pumped so that it is drawn through one of the filter elements. Periodically, the flow can be reversed, so that it is directed through the other filter element, at which time the first filter element can also be purged or back flushed. Advantageous waste treatment system arrangements are also provided for household, commercial, or transportation/marine use.
