ABSTRACT:
A portable curb inlet sediment filter which has a box filter frame and a primary baffle panel defining a filter chamber, to be filled with a particulate filter medium, such as gravel, for sediment removal, and an overflow chamber. The overflow chamber has at least one overflow baffle panel in order to provide a hydraulic opening and a peripheral end cap chamber. The end cap chamber is gravel filled in order to clarify water escaping around the front of the frame and into the hydraulic opening through the side panel. The filter frame and baffle panels are a mesh construction having apertures smaller in size than the particles of gravel to be contained.
