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.

Storm Shark

The Storm Shark range offers high-efficiency removal of suspended s

olids, hydrocarbons, and floatable debris from surface drainage networks. Developed in Germany, these units are engineered to meet and exceed the performance criteria outlined in German Stormwater Treatment standards DWA M153 D24 and D25.

 What sizes are available in Storm Shark?

The Storm Shark 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.

What are the benefits of Storm Shark?

• Easy to control and maintain
• Physical treatment of rainwater
• Effective removal of solids
• Underground system, therefore no space required
• No blocking possible
• Can be used on all surfaces from roofs to traffic and industrial areas

Downstream Defender

The Downstream Defender Select Separator, a novel Hydrodynamic Vortex Separator, is engineered for the efficacious treatment of stormwater runoff, thereby ensuring environmental compliance and meeting stringent water quality parameters.

What sizes are available in the Downstream Defender?

The sizes of the Downstream Defender range from 1.2m and 3.7m in diameter.

What are the benefits of the Downstream Defender?

• Available in an extended range of sizes helping engineers match flow rates and removal rates cost effectively, helping to cut costs.
• Design and installation on site is easier and cheaper as it can accept up to three inlets and a wider range of connecting pipes.
• Available in a plastic chamber which is ideal for sites where heavy plant access is restricted or fast installation is required.

V-Septor

The V-Septor employs advanced hydrodynamic separation principles to achieve the removal of sediment-associated contaminants. This is accomplished through the mechanisms & gravitational sedimentation and floatable debris capture.

What sizes are available in the V-Septor?

The ACO V-Septor product line encompasses a spectrum of sizes to address the requirements of both limited and extensive sites.

Furthermore, bespoke units can be fabricated to satisfy the specifications of complex installations.

What are the benefits of the V-Septor?

• Lightweight and easy to handle
• Forms part of the SuDS management train
• Great sediment storage capacity
• Removes solid pollution
• Reduces maintenance requirements of downstream attenuation storage and SuDs components
