In Brief:
HIL Technology, Inc. offers cost-effective non-point source pollution prevention with the Downstream Defender; a treatment device engineered to capture settleable solids, floatables, oil and grease from storm water runoff. It is one of the family of advanced Hydrodynamic Vortex Separators provided by HIL Technology, Inc. that augments gravitational forces with complex but stabilized vortex forces to maximize solids/liquids separation. The result is a compact separator that requires a smaller land area than conventional gravitational sedimentation. A floatables trap is incorporated within the same vessel.
