The Hydro Stormtrain® Series

The Series comprises our industry-leading surface water treatment devices, each delivering proven, measurable and repeatable surface water treatment performance. Each can be used independently, in combination, or alongside natural SuDS features.

Applications

Treats runoff from impermeable surfaces across a broad range of catchments.

New build or retrofit at-source pollution control for residential and commercial developments, highways and car parks. Control of siltation upstream of wetlands, ponds and basins.

Remove sediment, trash, oil, dissolved metals and nutrients from surface runoff using the natural power of biofiltration.

Targeted removals

• Fine particles
• Gross pollutants (litter / leaf debris)
• Liquid and sediment bound hydrocarbons
• Sediment bound heavy metals, sediment bound nutrients
• Dissolved pollutants

Benefits

• Remove high levels of pollutants with the natural and engineered filtration technology.
• The Hydro Biofilter™ contributes to attractive urban areas and street scenes and supports local biodiversity.
• The Hydro Biofilter™ is compact, but able to handle a high through flow, making it ideal for both new build and retrofit applications.
• The filter media and internal components are delivered pre-packaged in the concrete chamber to facilitate easy drop-in installation.
• Treated stormwater can be discharged to a drainage outflow, watercourse or onwards for infiltration if soil conditions allow.
• The Hydro Biofilter™ can also be integrated with secondary attenuation or infiltration such as the Stormcell® or Stormbloc® Optimum geocellular systems.

Applications

• Highway runoff
• Integration into street scene
• Low impact development SuDS schemes
• Supermarket car parks
• Park and ride schemes
• Watercourse, pond, basin and wetland protection
• Retrofit to residential, commercial and industrial sites
• First Defense®

Capture and retain stormwater sediment, litter and floatables in a unit that saves site space and adapts to smaller or logistically difficult site locations.

First Defense® is a versatile stormwater separator that works with single and multiple inlet pipes and inlet grates. It is easily maintained from the surface by standard vacuum tanker.

Targeted Pollutants

Coarse particles, gross pollutants (litter / leaf debris), Liquid and sediment bound hydrocarbons.

Benefits

• Space-saving, easy-to-install in standard sized chambers / manholes
• Variable configurations to help you fit First Defense® into a tight spot. It also works well with large pipes, multiple inlet pipes and inlet grates
• First Defense® retains the pollutants it captures. It eliminates excessive agitation of captured pollutants ensuring that they are not washed out during subsequent rainfall events
• Every First Defense® is delivered to site in a chamber – so installation is as easy as fitting any chamber / manhole

Applications

Treats runoff from impermeable surfaces across a broad range of catchments.

Provides at-source pollution control for residential and commercial developments, highways and car parks.

Advanced Hydrodynamic Vortex Separator

Capture and retain sediment, oils and floatables from stormwater runoff over a wide range of flows in a small footprint.

Downstream Defender® offers long maintenance intervals and consolidates pollutant removal to a single point in the drainage system.

Targeted removals

• Fine particles
• Gross pollutants (litter / leaf debris)
• Liquid and sediment bound hydrocarbons
• Sediment bound heavy metals and sediment bound nutrients

Benefits

• Downstream Defender® delivers high pollutant removal in a small footprint so it’s easier to install and therefore less expensive and less work.
• The Downstream Defender® is proven to prevent wash out of captured pollutants. Its internal components isolate the pollution storage areas ensuring that what is captured is retained, even during high flows.
• The Downstream Defender® can accommodate a change in outlet pipe direction to suit site specific requirements, helping meet Building Regulations without the need to construct a second manhole.
• Low headloss means more site flexibility and provides the option for a shallower site.

Applications

Treats runoff from any impermeable surfaces including highways, car parks and industrial areas. Also widely used to control siltation upstream of wetlands, ponds and basins, for example, as an alternative to a sediment forebay.

Fluidised Bed Up-Flow Filtration System

The Up-Flo™ Filter is an innovative surface water filtration technology that delivers a high-performance multi-stage treatment train within a single device.

The Up-Flo™ Filter combines sedimentation and screening with fluidised bed filtration technology to deliver high levels of performance.

Targeted removals

• Very fine particles
• Gross pollutants (litter / leaf debris)
• Liquid and sediment bound hydrocarbons
• Sediment bound heavy metals and sediment bound nutrients

Benefits

• Modular filtration components allow you to adapt your design to meet catchment needs.
• The Up-Flo™ Filter combines pre-treatment, screening and filtration, delivering highly efficient multi-stage treatment in one device.
• Higher loading rates result in a small treatment footprint, which saves construction time and money and makes for an easier installation.
• No moving parts means there is less opportunity for treatment disruption, while the design is suited to long-term maintenance. Longer media life means longer service intervals, and media bags are easily removed and replaced.

Application Information

For high-density urban environments where high pollutant loadings need to be managed in limited space.  For both new-build or retrofit situations for residential, commercial or industrial developments, highways and car parks.
