Filtration system for storm water catch basins

摘要

A silt filtration system is adapted for placement at an inlet of a storm water catch basin. The filtration system cooperates with a grate located adjacent a street curb at a mouth of the inlet to separate silt and debris entrained in storm water entering the catch basin. The filtration system includes a frame adapted for residing between the grate and the mouth of the inlet. The frame has elongated front, rear, and opposing side frame members. A filtration medium is supported within the frame, and is arranged to filter storm water entering the catch basin through the grate. A backsplash is attached to the rear frame member. The backsplash extends outwardly from the grate and upwardly into an open curb space between the grate and the curb, such that storm water splashing over the grate and into the curb space is deflected by the backsplash into the filtration medium within the frame.
