Catch basin erosion containment filter assembly

摘要

A catch basin erosion containment filter assembly. The filter assembly includes a rigid frame and a containment bag attached at its open end to the frame. The frame is adapted to be seated and/or held in the horizontal or vertical opening to a catch basin. The bag has one or more layers, preferably at least two layers. The outer layer is preferably a woven geotextile fabric and the inner layer is preferably a nonwoven geotextile fabric. A hydrocarbon absorbent layer, such as a nonwoven oileophilic fabric, may be located between the inner and outer layers for capturing spilled fuel and/or oil.
