Stormwater Treatment

Hydro International has launched the Hydro StormTrain® Series, a comprehensive toolbox of surface water treatment devices. The Hydro StormTrain® Series, provides an unrivalled range of performance-verified and internationally recognised technologies to meet current and expected water quality regulations in the UK. Four products, First Defense®, Downstream Defender®, Up-Flo™ Filter and Hydro BioCell™, are Sustainable Drainage Systems (SuDS) that can be used independently or in combination to deliver a Treatment Train that meets the water quality requirements for most sites. They can also be used to protect, enhance or enable natural SuDS features.

The Hydro StormTrain® Series of Surface Water Treatment Devices

First Defense® Vortex Separator

The First Defense® is an economical hydrodynamic vortex separator for effective removal of sediment, litter and oil from surface water runoff.  Captured pollutants are kept safely within the device keeping public areas free from harmful pollutants.

Suitable for at-source pollution control in small to medium size catchments, the First Defense® provides space-saving, easy-to-install surface water treatment in a standard size manhole.

The First Defense® internal components have been carefully designed to create a low energy rotational flow within the chamber to encourage pollution separation. This vortex separation allows sediments to settle to the sump whilst oils, floating litter and debris rise to the containment area.

Targeted Pollutants

•  Coarse particles.

•  Liquid and sediment bound hydrocarbons

•  Gross pollutants

Applications

The First Defense® reliably treats runoff from impermeable surfaces across a broad range of catchments.  Already proven in hundreds of installations across the globe, First Defense@reg; provides at-source pollution control for residential and commercial developments, highways and car parks.

The First Defense® also operates successfully as part of a management train alongside other proprietary or natural SuDS features, for example as treatment before infiltration. For more information.

Downstream® Advanced Hydrodynamic Vortex Separator

The Downstream Defender® is an advanced hydrodynamic vortex separator for the effective and reliable removal of fine particles along with oils and other floatable debris from surface water runoff.

Its innovative design delivers high efficiency across a wide range of flows in a much smaller footprint than conventional or other swirl-type devices and is the perfect choice for any catchment likely to convey high quantities of contamination.

The Downstream Defender® has unique flow modifying components that have been optimised to deliver unsurpassed capture and retention of pollutants during both frequent and extreme rainfall events.

The Downstream Defender® delivers high removal of pollutants through advanced hydrodynamic vortex separation across a wide range of flows, achieving a long, stable flow path to maximise pollutant capture from surface runoff.

The device is able to tackle an assortment of pollutants including gross debris, litter, hydrocarbons, coarse sediments, fine sediments and particulate organics. In the field, pollution captured by the Downstream Defender® has been shown to be as fine as the pollutants captured in much larger settling ponds.

Targeted Pollutants

•  Fine particles

•  Gross pollutants

•  Liquid and sediment bound hydrocarbons

•  Sediment bound heavy metals

•  Sediment bound nutrients

Applications

The Downstream Defender® reliably treats runoff from any impermeable surfaces including from highways, car parks and industrial areas.

It is also widely used to control siltation upstream of wetlands, ponds and basins, for example as an alternative to a sediment forebay, and can help to reduce the maintenance burden of natural SuDS features. Find out more ...

Up-Flo™ Filter - 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.

Easy to maintain and with low construction costs, the Up-Flo™ Filter achieves a high quality of surface water discharge in a much smaller footprint than alternative systems.

Targeted Pollutants

•  Very fine particles

•  Gross pollutants

•  Liquid and sediment bound hydrocarbons

•  Sediment bound heavy metals

•  Sediment bound nutrients.

Applications

The Up-Flo™ Filter is especially useful in high-density urban environments, where high pollutant loadings need to be managed in limited space or where it is difficult to control the quality of surface water runoff using conventional or natural SuDS techniques alone.

The Up-Flo™ Filter provides an effective solution in both new-build or retrofit situations for residential, commercial or industrial developments, highways or car parks. For more information

Hydro BioCell™ Bioretention System

The Hydro BioCell™ is an innovative bioretention and biofiltration system that harnesses the natural treatment action of vegetation and the filtration power of specially engineered soils.

From the surface Hydro BioCell™ looks like a normal tree box, with a suitable shrub or small tree protruding through a decorative grating in a concrete slab at pavement level. Underneath, the pre-cast concrete chamber contains a layer of enhanced mulch, on top of a unique soil filter medium to deliver high levels of surface water treatment.

Surface water is channelled into the unit through a kerbside inlet, through an inlet pipe or directly from the surface and flows through the mulch, plant and soil filter media, providing high-performance, high-flow filtration that targets sediment, hydrocarbons, heavy metals and nutrients.

Targeted Pollutants

•  Very fine particles

•  Gross pollutants

•  Dissolved, liquid and sediment bound hydrocarbons

•  Sediment bound heavy metals

•  Sediment bound nutrients

•  Dissolved nutrients.

Applications

Hydro BioCell™ engineers in nature's way to enhance any urban environment even where space is at a premium or where a retrofit surface water treatment solution is required. Suitable for residential or commercial settings, car parks and highways.  For more information ....
