The SDD3 by NEXT Stormwater Solutions is a hydrodynamic oil and grit separator that utilizes both gravitational and centrifugal forces to capture and retain suspended sediments, floating particles and oils from Stormwater runoff.
The SDD3 unique design ensures optimal storm water treatment during light and heavy rainfall events.
Advantages
Can be installed in series or in parallel because of its bypass system
Strong and durable structure made in reinforced concrete able to support Cl-625, H-25 ans HS-20 charges
The installation and the maintenance are easy to do from the surface
Double vortex to maximize the performance
Internal aluminium components (5052-H32) have high mechanical properties and excellent corrosion resistance
The SDD3 storm water treatment system has one of the best load rates in the industry, which translates into superior performance. The SDD3 system effectively removes sediment and oils from stormwater.
When sizing the SDD3, it is important to take into account the standards applicable to hydrodynamic separators, the treatment flow rate and the provincial and municipal regulatory control criteria targeted by each project. This is also necessary when you compare the performance of SDD3 to other technologies.
The efficiency of a sediment separator system such as SDD3 varies depending on the loading rate and the particle size used for its evaluation. Our system guarantees optimal rainwater treatment for a wide range of flow rates.
How it works
The water to be treated enters the unit through the main line (series installation) or through a bypass line (parallel installation)
The water is directed to the two vortices where the centrifugal forces, generated by the circular movement of the water, separate the suspended particles and the oils
The particles are decanted and collected at the bottom of the unit
The oils are transported (by gravitational ascent) and stored separately under the oblique plate
The treated water is finally directed to the outlet pipe.
SDD3 consists of high-quality external and internal components
Internal by-pass allows both online and offline configuration
100% designed and manufactured in Canada
Several configurations and options to fit every project's needs
