Surface Water Treatment Vortex Hydraulic Separators

Effective treatment of stormwater runoff

Precipitation interacting with impervious surfaces within the built environment generates stormwater runoff. This runoff often contains pollutants, including suspended solids, hydrocarbons. Upon entering stormwater conveyance systems, these pollutants are transported and ultimately discharged into receiving waters, necessitating robust stormwater management practices.

What is a Vortex Hydraulic Separator?

Vortex Hydraulic Separators are engineered to facilitate the separation and retention of insoluble particulate matter, such as silt, hydrocarbons, and floatable debris, from surface water drainage. These systems are designed to function within Sustainable Drainage Systems (SuDS), providing a reliable water quality treatment stage that contributes to improved downstream amenity and biodiversity.

STORMSHARK

The STORMSHARK is a cutting-edge hydrodynamic vortex separator that sets the standard in the industry with its unique patented design and exceptional performance. Engineered specifically for Sustainable Drainage Systems (SuDS) treatment trains, the STORMSHARK delivers outstanding water quality treatment while significantly enhancing amenity and bio diversity downstream. It serves as a powerful guardian, effectively protecting controlled waters from harmful sediment-bound pollutants.

Manufactured in Germany for the global stormwater management market, every model in the STORMSHARK range not only meets but exceeds the most stringent German Stormwater Treatment standards, including DWA M153 D24 and D25. Furthermore, the STORMSHARK has undergone rigorous testing in the United States, fully complying with the guidelines established by the New Jersey Department of Environmental Protection (NJDEP).

The STORMSHARK's remarkable flexibility allows it to operate both online and offline, seamlessly integrating with or without an external bypass unit. This adaptability positions it as the definitive solution for a wide range of multi-treatment water purification processes

 What sizes are available in STORMSHARK?

The STORMSHARK sizes range to suit 750mm diameter chamber to 1,800mm diameter chamber or larger if required. These include the option of a stand alone unit, installed on site, inside a concrete, PE or GRP chamber or a pre-fitted unit inside a high strength PE twinwall chamber.

Design Certification and Testing 

• NJDEP 2021
• NRW Trennerlass (Independent German Lab & field test)
• DIBt

Performance

The STORMSHARK removes sediment bound contaminants. Available in differing sizes to suit site flows and conditions. The STORMSHARK removes over 50% of fine TSS (0−200 microns, median size 75 microns) at design flows and up to 99% of TDS 0.1 to 0.4mm (coarse).

Key Features
