The Hydro-Industrial™ Stormwater Separator is an advanced hydrodynamic vortex separator that provides impressive and reliable removal of fine and coarse particles, hydrocarbons and floatable debris from industrial surface water runoff, delivering high levels of stormwater treatment over a wide range of flow rates to keep businesses compliant with local discharge regulations.

Based on the Downstream Defender® and available in a range of sizes, it can function as either pre-treatment or as a stand-alone surface water treatment device, providing engineers and owners with a flexible, cost-effective stormwater management option. 

Stay compliant

The Hydro-Industrial™ Stormwater Separator delivers effective surface water pollutant removal, helping industrial businesses to remain compliant with local environmental regulations and preventing potentially costly and damaging compliance breaches.  

Save space and money

The Hydro-Industrial™ Stormwater Separator can treat high peak flows in as little as half of the footprint of alternative structural systems. A smaller footprint means an easier install that’s less expensive and requires less work.

The system is proven to prevent washout of captured pollutants, providing peace of mind to owners. Carefully designed internal components isolate the pollution storage areas, ensuring that what is captured is retained, even during high flows.

• Fine and coarse particles / total suspended solids (TSS)
• Floatable trash and debris
• Liquid- and sediment-bound oils and hydrocarbons
• Sediment-bound heavy metals
• Sediment-bound nutrients
