SurfSep units use Continuous Deflective Separation (CDS) technology. Originally developed in Australia, this non-blocking screening technology has been independently validated by world-class research organisations CSIRO (Commonwealth Scientific & Industrial Research Organisation), CRCCH (Co-operative Research Centre for Catchment Hydrology) & UCLA (University of California, Los Angeles)

Operating Principle

The CDS technology offers highly efficient separation of settleable solids (95% of all particles greater than 550 microns) and achieves 100 percent capture of floatable material >1mm.

How it Works

Water and pollutants enter the system and are introduced tangentially inside the separation chamber forming a circular flow motion. Floatables and suspended solids are diverted to the slow moving centre of the flow. Negatively buoyant solids settle out to an undisturbed sump chamber below, while the water passes concurrently through the separation scheme. Floatables remain at the water surface and retained within the screen.

Advantages

• Effective: Capturing more than 95% of solid pollutants
• Rapid Installation: Comes in self-contained manhole that has BBA approval. Just connect the inlet and outlet.
• Non-Blocking: Unique design takes advantage of indirect filtration and properly proportioned hydraulic forces that virtually makes the unit unblockable.
• Low Maintenance Costs: The unit has no moving parts and is fabricated of durable materials.
• High Flow Effectiveness: The technology remains highly effective across a broad spectrum of flow ranges.
