ABSTRACT:
A waste water filtering apparatus includes a vertically extending filter housing having a plurality of filter tubes disposed therein. At least one of the filter tubes has an opening in the bottom end thereof and is closed at the top wherein waste water to be filtered flows in through the interior of the filter tube and out through openings in the walls of the filter tube into the interior of the filter housing. A second filter tube is provided with a closed bottom end and an open outlet end in flow communication with a discharge outlet from the filter housing. The second filter tube is in spaced parallel relation with the first filter tube whereby water flowing in the interior of the housing flows into the second filter tube and flows upwardly and out of openings in the top end of the filter tube which is in flow communication with the outlet discharge of the filter.
