The BMS Stormbreaker Defender is a low footprint interceptor (separator) capable of removing silt, particles and floating pollutants such as oil/hydrocarbons/debris and contaminated settling solids from surface or storm water flows. It can also be used before drain discharges direct in water courses to prevent pollution from silt and floating debris such as plastic bottles, bags, rags, cigarette butts etc.
How Does it Work?
The Stormbreaker Defender has no moving parts and utilises natural vortex flow hydrodynamics. It has a unique internal geometry that removes silt/particles and captures floating pollutants/debris while minimising head-losses across the chamber. Effective heavy metal removal also takes place commensurate with particle size. It can be used upstream or downstream of surface water treatment systems such as attenuation or Sustainable Urban Drainage Systems (SuDS), ponds/reservoirs, holding tanks or before discharge to water courses as a means of pollutant removal.
Installation
The Stormbreaker Defender is ‘value engineered product’ that is delivered ‘ready to go’ and is simple to install for both new and existing applications. Simply lower onto a base via the integral lifting hooks, connect the inlet & outlet pipes and install a 225 mm leanmix concrete surround. A large separate concrete manhole is not required. The max unit diameter is 2.3 m meaning that all sizes can be uniquely delivered via a standard truck or container. Full installation instructions are available.
Design
The Stormbreaker Defender was developed by BMS in conjunction with the National University of Ireland (NUI) Galway with the support of Enterprise Ireland. Extensive background research and full scale laboratory testing was conducted by an expert in the field of vortex dynamics resulting in a class leading ISO 9001:2015 Quality product fully manufactured and developed in Europe. It has extensive background data verifying both its selection and performance.
Materials/Manufacture
All BMS Stormbreaker Defenders are custom manufactured in corrosion/rot proof GRP (Glass Reinforced Polyester) using only CE marked materials and Lloyds rated resins in Ireland/EU under ISO 9001:2015 and have an expected lifespan of 50+ years.
To order a Stormbreaker Defender the following information is required:
- Average Flow and Peak Flow through the unit e.g. 0.5 l/s – 250 l/s.
- Inlet/Outlet Pipe Size
Flow Phases
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.
Maintenance
The Stormbreaker Defender is very easy to maintain with all maintenance from ground level. Full instructions are available.
