ABSTRACT:
A waste water filter for use within a septic tank. The waste water filter comprises a shield including an upstanding peripheral wall, the peripheral wall defining a shield interior within the shield. The shield further includes an inlet opening for allowing the entry of unfiltered wastewater into the shield interior. A filter enclosure is disposed within the shield interior at a spaced apart distance from the shield. The filter enclosure includes an upstanding peripheral wall, a top end, and a bottom end. The bottom end includes a bottom panel for preventing the passage of unfiltered waste water into filter enclosure. The filter enclosure further includes at least one filter surface disposed intermediate the top and bottom ends of the filter enclosure for allowing the passage of water restricting the passage of solids. A filter support is disposed intermediate the top and bottom ends of the filter enclosure adjacent to the filter surface and provides a supporting reinforcement surface for the filter surface during the filtering of waste water to prevent the filter surface from collapsing inwardly away from the shield. The filter support includes at least one opening therein for the passage of filtered waste water into filter enclosure. An outlet is disposed within the filter enclosure for discharging filtered waste water. The filter surface is typically disposed in a substantially vertical orientation and the filter support is typically disposed inside of the filter surface within the filter enclosure.
