Overview
Innovative treatment solutions are needed to prevent pollutants
from reaching valuable water resources. The Downstream Defender®
meets this challenge. The Downstream Defender® is an
advanced hydrodynamic separator designed to remove sediment,
floatables and associated pollutants from stormwater.
The Downstream Defender® provides greater pollutant removal
and retention in a smaller footprint compared to conventional
gravity or simple swirl-type devices. Flow modifying components
create a stable hydrodynamic flow regime that is ideal for
solids / liquid separation and preventing washouts over a
wide range of flow rates.
Captured sediments are contained in an isolated storage area.
A built-in trap retains oil and floatables. These key features
prevent re-entrainment of pollutants even under extreme surcharge
conditions.
