Stormbreaker Defender - Hydrodynamic Vortex Separator System

The BMS Stormbreaker Defender is a low footprint storm water interceptor capable of removing particles, floating debris and floating pollutants such as oil/hydrocarbons and contaminated settling solids from surface or storm water.  The Stormbreaker Defender can be used up or down stream of surface water holding systems and attenuation/holding ponds as a means of pollutant removal.

Large BMS Stormbreaker Defender

The system has no moving parts and utilises natural vortex flow hydrodynamics to remove particles.  It has a unique internal geometry to capture floating pollutants and debris as well as minimise head-losses across the chamber.

Installation

The Stormbreaker Defender is simple to install and can be used for both new and existing applications.  It is delivered ‘ready to go’ and only requires the connection of the inlet & outlet pipes.  It does not require a concrete surround, separate manhole or other supports as is the case with other commercially available systems providing a potentially large saving.  The max unit diameter is 2.3 m which means that all sizes can be uniquely deliver via a standard truck or container.

How it works

1.Dry Weather

Stormbreaker Defender Dry Weather Flow

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.

2. 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 removal and to minimise head loss.

 

 

3. 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.

 

4. Peak Flow Storm Event

When a peak flow rainfall event is experience 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.
