Capture and retain sediment, oils and floatables from stormwater runoff over a wide range of flows in a small footprint.
Downstream Defender® is an advanced hydrodynamic vortex separator that reliably captures and retains sediments, oil, trash and floatables from surface water runoff.
A compact, low-maintenance stormwater treatment BMP, the Downstream Defender® enables engineers to deliver effective pollutant removal at a single point in the drainage system.
Overview
The Downstream Defender® is an advanced hydrodynamic vortex separator that provides impressive and reliable removal of fine and coarse particles, hydrocarbons and floatable debris from surface water runoff, delivering high levels of stormwater treatment over a wide range of flow rates.
Available in a range of sizes, it can function as either pretreatment or as a stand-alone device, providing engineers and contractors with a flexible, cost-effective stormwater management option.
Targeted Pollutants:
Fine and coarse particles / total suspended solids (TSS)
Floatable trash and debris - now available with 5mm screen to meet 100% trash capture TMDL
Liquid- and sediment-bound oils and hydrocarbons
Sediment-bound heavy metals
Sediment-bound nutrients
Applications:
The Downstream Defender® reliably treats surface water runoff from impermeable surfaces including highways, car parks, industrial areas and urban developments
As part of green infrastructure, LID or LEED systems
Areas where high solids and trash capture are a must
Control of silting upstream of wetlands, ponds and basins
Industrial stormwater pollution control
