HydroShark – Advanced Hydrodynamic Particle Separator
HydroShark 1000 Advanced Hydrodynamic Particle Separator
The 3P HydroShark® Advanced Hydrodynamic Particle Separator removes suspended solids (SS or TSS) from the stormwater runoff within SUDS Treatment Trains. This patented and tested Proprietary Treatment Device protects surface water and groundwater infiltration systems. This Manufactured Treatment Device (MTD) device meets and exceeds all German stormwater treatment standards under DWA M153 D24 and D25. Tested to NJDEP 2021. Also tested to the British Water Code of Practice Protocol, details on request. It can be used online or offline with or without an external bypass unit.
Available in plastic or concrete chambers. Ideally deployed within a water quality SUDS treatment train. Simple to deploy, simple to maintain. A HARD SUDS device, this hydrodynamic particle separator is used in reducing hazards of pollution, often in advance of Green Infrastructure.
Incoming stormwater is deflected into a radial (vortex) flow pattern via a submerged deflector plate. The vortex set up within the inner tapering swirl chamber generates the so-called teacup effect, allowing sedimentation of suspended particles to take place. Particles sink and settle into the sludge trap below. This sludge chamber is hydraulically isolated from the main flow chamber by means of a flow breaker grate and baffle walls promote sedimentation. Remobilisation of previously settled solids during heavy rainfall events is impossible. This is tested and certified as such.
The unique balancing toothed weir ensures that a homogeneous even flow pathway prevails. Because of the toothed weir, waters in the outer chamber of the particle separator must flow upwards, distributed evenly around the whole diameter of the unit. This even flowpath in the separator is a critical design element. Unlike some other HDS devices, there can be no short-circuit flow currents in the system. Even at high flows the 3P HydroShark HDS unit has an even flow distribution with maximum flow distance ensured. Floatable (Lightweight) materials such as oils, litter or pollen are effectively retained at surface because they cannot submerge beneath the inner chamber wall. There is no head loss between the inlet and outlet pipes. The system cannot airlock. The 3P HydroShark® can treat water from all surfaces, roof areas, car parks, roads, runways and commercial and industrial areas. So it can be used to meet Simple Index from CIRIA SUDS Manual recommendations. See Simple Index Approach in Chapter 26 of C753. Treats sediment-bound metals, hydrocarbons and of course TSS Fine and TSS Coarse. Mitigation Indices to the British Water protocol are available on request. (Code of Practice: Assessment of Manufactured Devices Designed to Treat Surface Water Runoff).
The 3P HydroShark is specified and sold worldwide, including in the UK, ROI, Germany, USA, Austria, France, Italy, Sweden, Finland, Denmark, Spain, Portugal, Dubai, Qatar, and Croatia amongst others – proven reliable sedimentation and retention performance.
Eight sizes of 3P HydroShark® are available, HSK750, HSK1000, HSK1200, HSK1500, HSK1800, HSK2000, HSK2500, HSK3000. This is a class-leading choice of Hydrodynamic Separators.
How the advanced hydrodynamic particle separator works
- The incoming stormwater is deflected into a radial flow pattern, a swirl separation technology.
- Solids settle down into the sludge chamber, floatables are retained at the surface.
- Solids are retained in the sludge chamber below the treatment chamber. Remobilisation of retained solids is not possible, flow baffles and an isolation grill prevent this. Test data proves this.
- Cleaned water flows up the outer chamber in an even flow distribution. Because of the toothed weir, the Sharks teeth ensure no short circuit pathways are possible.
- Water flows evenly over the toothed balancing weir to the annular space surrounding the treatment chamber. The absence of one outlet pipe from the treatment chamber room prevents preferential pathways being generated within the treatment zone, even at high flows.
- Clean treated storm water passes over the teeth to the outlet collection channel, and discharges to the water environment or the next SUDS Treatment Train stage.
Technical Overview of the 3P Hydrodynamic Separator
Maximum Treatment Flow Rates (l/s) are from 11 through 20, 45, 65, 80, 125 and 180 litres/second. Treatment Flow Rates are calculated according to the NJDEP protocol (MTFR). These Treatment Water Quality Rates can be adjusted to suit site-specific design treatment requirements. This is especially so when the hard SUDS Hydrodymanic Separator is combined with other treatment devices within a SUDS Treatment Train, including SUDS wetlands, ponds, swales or other green infrastructure.

MTFR, TFR, Treatment Water Quality and other flow rates can be discussed with 3P directly or with our partner suppliers. We aspire to the clarity of performance. Mitigation Indices are available. Can be deployed with other 3P treatment devices.
* available as bare insert, or pre-fitted in Chambers: PE Chamber (Product Code +PE), Concrete Chamber (Product Code +CN). Height of Flow Breaker Plates can be increased to allow extra Sediment Storage in the Sludge Chamber capacity.
** larger shaft diameters will increase this capacity. See datasheets.
Certifications
This Manufactured Treatment Device (MTD) is British Water Code of Practice certified. It also exceeds all German stormwater treatment standards under DWA -A 138 (replaced DWA M 153) DWA for groundwater discharges and DWA-A102 for surface water discharge. The 3P HydroShark vortex separator is also tested according to NRW Trennerlass and certified by an independent German lab tested according to the DiBT principles.
It was the first device worldwide to be both tested and certified to NJDEP/NJCAT 2021. It was previously pre-tested to the old now withdrawn NJDEP/NJCAT 2013.
3P standard Treatment Flow Rates are based on the NJDEP protocol from the USA. This is because whilst NJDEP has no regulatory role or authority in the UK, or the Republic of Ireland, it has been a widely recognised design standard for solids separation in stormwater treatment in many countries. It has for many years been at the root of many stormwater treatment designs still in the UK.
All models of the 3P HydroSharks have been lab-tested according to DiBT principles. These more detailed pass/fail protocols of course require a far higher removal rate of sediments and provide independently certified figures for the performance of the 3P HydroShark, including the retention of oils and microplastics.
The 3P HydroShark has also been tested for light liquid retention > 98% according to DIN EN 858-1.
The 3P HydroShark is specified and sold worldwide, including in the UK, ROI, Germany, USA, Austria, France, Italy, Sweden, Finland, Denmark, Spain, Portugal, Dubai, Qatar, and Croatia amongst others – proven reliable sedimentation and retention performance.
For further explanation of the NJDEP protocols or the BW protocol please contact us. We do live in an imperfect world…. However, unlike many Interceptor and stormwater treatment manufacturers, we do not use Maximum Hydraulic Flows or EN858 flow rates as “treatment flow” rates for TSS removal.
We also will never assume in a design that all polluting heavy metals are sediment-bound, to purport a higher metals Mitigation Index.
