To prevent storm water from a combined sewer overflow overwhelming the maximum capacity of a treatment works, a Hydro CSO screening device and Hydro-Brake® hydrodynamic flow control can operate during peak storm events.
This combination can be designed to store or spill screened storm flow and to prevent downstream flooding, while transferring screenings to the treatment plant.
The Heliscreen® is a compact powered CSO screen with the ability to operate under surcharged conditions. With low headloss and a small footprint, the Heliscreen® is ideal for retrofit installations with hydraulic or physical site constraints.
Hydro-Brake Optimum® is an independently accredited, self-activating vortex flow control with no moving parts and no power requirement. Hydro-Brake Optimum® is used to control the forward flow of water.
The Hydro-Jet® Screen is a self-activating, self-cleansing, CSO screening system with no moving parts and no power requirements. A compact device with high hydraulic throughput, the Hydro-Jet® Screen is perfectly suited for small to medium size CSO sites.
The Hydro-Static® Screen is a non-powered screening technology suitable for sites with infrequent overflows.
The Storm King® Overflow with Swirl-Cleanse™ Screen is an advanced hydrodynamic vortex separator with an integral unique, non-powered, self-cleansing screen. Storm King® Overflow with Swirl-Cleanse™ Screen
