SURFSEP POLLUTANT TRAP

The Isolator™ Row is a stormwater filtration zone that removes almost all particles less than 40 micron and a very high percentage of associated pollutants typically found in Stormwater.

Protect your downstream water courses by installing a SurfSep Screening unit. When installed upstream of any SUDs system, the SurfSep unit protects the receiving system from fine solids and debris that would otherwise accumulate overtime, rendering the SUDs non-operational.

The Continuous Deflective Separation (CDS) technology was developed in Australia.

The 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 550microns) 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 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.

Assured Pollutant Capture:
All materials captured are retained during high flow conditions. Neutrally buoyant particles are captured. Various independent field trials have shown that high levels of phosphates, Heavy Metals and Hydrocarbons are removed from the flow
