HydroShark – Advanced Hydrodynamic Particle Separator

Hyrdoshark DN1000 Particle Separator from 3P TechnikThe 3P HydroShark® Advanced Hydrodynamic Particle Separator removes  suspended solids (SS) from the stormwater runoff. This patented and tested Proprietary Treatment Device protects surface water and groundwater infiltration systems.  This device meets and exceeds all German stormwater treatment standards under DWA M153 D24 and D25. It can be used on-line or off-line, and with or without an external by-pass unit.

Available in plastic or concrete chambers. Ideal in a water quality treatment train. Simple to deploy, simple to maintain.

The incoming storm water is deflected into a radial flow pattern via a submerged plate. The vortex set up within the 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. Remobilisation of the settled solids during heavy rainfall events is impossible and is tested and certified as such.

The cleaned water in the outer section of the system flows evenly upwards. The unique balancing toothed weir ensures that a homogeneous even flow pathway prevails. Unlike some other devices, there can be no short circuit currents in the system, even at high flows.  Lightweight materials such as oils, litters or pollen are effectively retained because they cannot submerge beneath the inner chamber wall. There is no head loss between the inlet and outlet pipes. The system cannot air lock. The 3P HydroShark® can be deployed to treat water from all surfaces,  roof areas, car parks, roads, runways and commercial and industrial areas. 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 available on request.

Seven sizes of 3P HydroShark® are available, HSK750, HSK1000, HSK1200, HSK1500, HSK2000, HSK2500, HSK3000.

How the HydroShark particle separator from 3P Technik WorksHow the advanced hydrodynamic particle separator works

  1. The incoming storm water is deflected into a radial flow pattern, swirl technology.
  2. Solids settle down into the sludge chamber, floatables are retained at the surface.
  3. 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.
  4. Cleaned water flows up the outer chamber in an even flow distribution.  No short circuit pathways are possible.
  5. Water flows evenly over the toothed balancing weir to the annular space surrounding the treatment chamber.  The absence of one outlet pipe prevents preferential pathways being generated within the treatment zone, even at high flows.
  6. Clean treated storm water passes to the outlet, and discharges to the water environment or the next treatment train stage.

Technical Overview

Maximum Treatment Flow Rates (l/s) are from 11 through 20, 45, 80, 125 and 180 litres/second.  Flow rates are calculated according to the NJDEP protocol. These Treatment Water Quality Rates can be adjusted to suit site specific design treatment requirements, especially when combined with other treatment devices or feeding into a surface water treatment train of green infrastructure.
