HydroSystem1000 SUDS Multi-process Treatment Device
Multi-process Hard SUDS stormwater treatment device, four treatment stages. Connectable surface area 500 to 1000m2 depending on contamination loading from the runoff. Extendable connected area, after SUDS flow control devices. Fully DIBt Approved. See Ch 14 SuDS manual, multi process, multi stage treatment process device. For installation within standard DN1000 chambers of concrete and PE.
Multi-process SUDS Treatment Device Stages
- The stormwater from the connected area is fed into the inlet, at the lower end of the shaft. A deflector plate sets up a radial/vortex flow.
- Sedimentation of particles, especially of the silt and sand faction takes place in the hydrodynamic particle separator. This is due to turbulent secondary flows within a radial laminar flow regime. Vortex separation, proven water treatment technology.
- The settled solids are fully retained (DiBT proven). They are evacuated via the central bypass tube periodically at site-specific intervals.
- Four multi-process filter elements are located within the HydroSystem filtration stage. As the waters flow upwards the finer particles are filtered out, whilst the dissolved pollutants are precipitated and absorbed. The multi-process filter is easily back-washed, and if completely clogged or exhausted, is easily replaced. Metals once bound cannot be remobilised from the filters by road salts in the incoming stormwater, DiBT proven.
- Clean water above the filter elements passes to discharge via an oil trap/floatables assembly. Normal concentrations of dissolved oils are fully retained within the filter elements. Discharged to ground or surface waters in a SUDS system or other green infrastructure.
Stormwater Pollutant Removal
The filter media removes pollutants like PAH´s, hydrocarbons and heavy metals. Furthermore, it binds phosphorus, and removes ammonium and nitrate from stormwater runoff (see brochure for details). Phosphorus removal via a HydroSystem provides an extremely useful tool for nutrient neutrality schemes for new development projects. The multistage four-step treatment train removes both solids and dissolved pollutants.” we can remove 40% of dissolved P with our proven media technology.
HS1000 Stormwater Treatment Device range:
| Filter Type | Product-No. | Nature of the Run-off Surface | Run-off Surface Area |
|---|---|---|---|
| Traffic | 3100110 | Slightly polluted traffic areas (side streets, staff car parks, yards) | 750m² |
| Heavy Traffic | 3100120 | Highly polluted traffic areas (supermarket car parks, main roads, HGV access roads) | 500m² |
| Roof | 3100100 | Roofs without a significant proportion of uncoated metals (<50m²) | 1000m² |
| Metal | 3100130 | Roofs made with uncoated metals (copper, zinc, lead). Also ideal for treatment of metal processing and galvanising yards. | 500m² |

Our DiBT approved stormwater products are supplied through a small selection of trained partners.
The 3P HydroSystem multi-process multi stage treatment devices fully 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). In so doing, they provide a certainty of performance standard that will be understood and accepted by the EA in England.
Ideal for the treatment of run off from zinc galvanizing and metal processing yards, metal recycling sites, waste amenity sites, larger car parks, and all commercial areas.
