The BMS Stormbreaker Defender utilises principles of vortex hydrodynamics to separate grit from storm water whereas baffles and weirs within the unit trap floatable pollutants. The induced vortex flow pushes heavy solids to the bottom of the unit and separates out floating pollutants via an internal pipe and weir. Low flow periods are a perfect time to inspect the unit to check the internal silt level. Should emptying be required this can easily be done with a suction tanker
Stormbreaker Defender Normal Storm Event
The Stormbreaker Defender is designed on the basis of average and peak flow. It works maximally at average flows separating out 90% of solids and floating silt/debris. Each Stormbreaker Defender is selected on an individual basis to maximise grit/floating pollutant removal and to minimise head loss.
Stormbreaker Defender Intensifying Stormwater Event
Heavier rainfall generally results in the transport of heavier particles and debris, this enhances separation within the Stormbreaker Defender. The majority of any solids/debris will be conveyed to the Stormbreaker Defender during the first flush of any rain fall event. Floating debris pollutants are retained in the chamber due to the internal pipe configuration.
Stormbreaker Defender Peak Flow Storm Event
When a peak flow rainfall event is experienced the full pollutant load will have been delivered to the Stormbreaker Defender, meaning separation and settlement has already taken place. The Stormbreaker Defender is designed to maintain solids within the unit during peak flow events minimising any wash through.
