Downstream Defender Performance Verification: OK-110 Sediment Capture

Downstream Defender® performance verification: OK-110 sediment capture. 

To quantify pollutant removal efficacy, a full-scale 4-ft diameter Downstream Defender® was tested under controlled laboratory conditions using silica brand OK-110. The resulting test data demonstrates 80% removal of fine sediment for all flows up to 1.56 cfs and 65% efficiency at the highest flow rate tested at 2.2 cfs.
