ABSTRACT:
A waste water treatment plant is disclosed that uses aerobic bacteria to digest solid particles in the waste water. The plant includes a filter located just upstream of the outlet through which the water leaves the plant. The filter comprises an elongated sheet of plastic material that is wound upon itself with adjacent layers narrowly spaced to form an elongated narrow passageway. Aerobic bacteria grows on the walls of the passageway and across the top of the filter to digest the last solid particles from the water as the water slowly rises through the filter.
