3P Technik is an established EU wide market leader in stormwater multi-process filtration and vortex separation systems. The concept of using a multi process unit in a SuDS/WSUD treatment train is accepted in UK treatment train designs. Historically, the UK market only used basic grit separators, to remove the heavier sediments out of suspension (TSS Coarse etc).
UK standards and regulators increasingly require runoff from more contaminated areas like highways, busy commercial car parks and industrial yards to treat by removing a wide range of contaminants, including PAHs and heavy metals such as zinc and copper in both solid and dissolved form. In countries like Germany, Switzerland and the Scandinavian countries, tight standards are imposed on discharges of stormwater runoff to protect both surface waters and groundwaters alike. UK LFAs and SABs now understand the importance of treatment meaning removal from the wider soil and water environment.
Even the green infrastructure focused CIRIA SuDS manual acknowledges the need to focus on finer particles at many sites (see Chapter 14, Part D Technical detail, pg 284). This requires designers to assess the fate of particles finer than 64 microns, so called PM64. Treatment involves removing silts and clays, as well as the dissolved phases of metal contaminants. Many older generation particle separation devices cannot remove these fine particles. Or they only do it only for a while. Or disastrously they simply release the retained bound heavy metals once road salt in the incoming stormwater reaches the retained sediments. This creates a huge spike in metal contamination in the receiving water, in winter time, which can have lethal effects on flora and fauna.
The British Water Code Of Practice specifically acknowledges the need to consider road salting effects, and the fate of PM64 fine particles within the BW document Assessment of Manufactured Treatment Devices Designed To Treat Surface Water Runoff. 3P UK were pleased to be a contributor to the the BW Code of Practice. It is a critical oversight that nowhere does the CIRIA SUDS Manual define the particle size distribution when discussing the fate of TSS and their removal from the environment.
All 3P products are designed and certified to perform to certified standards and so prevent damage to fragile and important ecosystems. These units pass the DiBT standard, as referenced in the CIRIA SuDS manual (see Ch 14 Part D: Technical Detail, and Ch 26, Part E: Supporting Guidance). 3P Stormwater treatment units all meet a certain performance standard that will be understood and accepted by the EA and LLFAs in England and NRW and SABS in Wales.
The 3P Hydrosystem is particularly relevant for polluted water treatment in sensitive catchment areas and Sites of Special Scientific Interest (SSSIs) . Typically deployed after a flow control unit, the HS range delivers effective stormwater pollution prevention plans (SWPPP) and can be part of stormwater best management practices (BMP). 3P Hydrosystem Ideal for the treatment of run off from zinc galvanizing yards, metal recycling sites, other metal processing yards and other areas of industry.
Please feel free to Contact Us to discuss your particular treatment train requirements and the Mitigation Indices of our products. 3P UK and 3P GmbH were corresponding members of the British Water Treatment Devices Technical Standardisation Group.
Our UK sales partners can supply units to site fabricated in bespoke chambers to meet individual site design SUDS solutions.
Based as we are in Wales, we are delighted and proud to see the Welsh Government standards on water management have now been implemented.
The 3P HydroShark® hydro-dynamic particle separator removes suspended solids (SS) from the stormwater runoff. This patented and certified Proprietary Treatment Device protects surface water and groundwater infiltration systems. NJDEP certification.
Specialist rainwater filter for installation within standard manhole shafts, 1000mm diameter. Connectable surface area 500 to 1000m2 depending on contamination level of the runoff. DIBt Approved.
Special stormwater treatment plant for installation directly in the ground. For roof areas and traffic areas from 100 to 175 m², depending on the type of filter. The cleaned water has such an excellent water quality that it can be discharged directly into soakaways, surface waters and the wider environment.
Hydro Filter Drain
This innovative and class leading modular channel drain design is based on a standard 300mm drainage channel width. Enables stormwaters from high traffic areas (car parks and roads), industrial areas and metal roofs to be cleaned at site level, and then discharged safely to ground or surface water bodies locally, or safely with certainty of treatment to green swales and ponds.
Hydro Gulley (Buda Vinci)
Hydrofilter ® Gulley is a street gully filter. Stormwater runoff from road surfaces are treated locally therefore significantly reducing the space required for stormwater treatment.
