ABSTRACT:
A filter cloth of long pile fiber bundles is used as a tertiary filter in a wastewater processing method. The filter may be backwashed by a rotating suction head which does not touch the filter cloth. A combination of countercurrent and horizontal flow dislodges entrained solids from the filter cloth. Mounting of the filter media as modular components permits increased capacity within a single tank while avoiding down time in changeover of filter media.
