Overview of StormProtector

The StormProtector by Protector is a dual chamber storm-water treatment system fully equipped with internal bypass and Coalesce filtration system. The system has a large retention and settlement chamber to provide a smooth flow for the secondary chamber system thereby allowing complete filtration to the needs required of your site. With a full range of sizing along with a wide range of inlet and discharge sizes, the Protector team can provide solutions for any of your storm-water retention and filtration needs with the StormProtector series.

Stormprotector overview

The StormProtector’s most efficient design is its removal of oils and hydrocarbons from storm-water, performing at 95% removal of hydrocarbons. With high amounts of oil run off from vehicles in car parks, garage forecourts and other various high traffic areas, removal of these oils and hydrocarbons from out waterways is of the upmost importance. The system is designed with a coalesce filter that is able to remove a high majority of oil, and depending on whether the installation is high or low risk, can ensure a release of 5mg/L of oil. The system is also capable of removing sedimentation and suspended solids through the use of the settlement chamber, silt baffle and the dropper tubes implementation to ensure that these contaminants to do not reach the coalesce filter, preventing clogging and ensuring long life. The system also features removal techniques such as adsorption, attachment and interception to remove nutrients and other unwanted contaminants in the filtration process.

The Environment Protection Agency has published Pollution Prevention Guidelines ‘Use and Design of Oil Separators in Surface Water Drainage Systems: PPG3’. These set out the standards with which separators must comply and assist in deciding on the need for a separator at a site and the size and type that is appropriate. These Pollution Prevention Guidelines PPG3 require separators to be tested in accordance with the standard test procedure based on the European Standard BSEN858-1:2002. These standards and protocols were strictly adhered to in the design of the StormProtector and ensure safe and viable removal of pollutants.

  1. Water enters through the flame dip inlet, preventing flammable gasses from entering the STORMPROTECTOR and providing non-turbulent inlet flow.
  2. Water builds up in the Settlement chamber. As the stormwater level rises, the sediments settle in this chamber, to the bottom of the tank under the force of gravity. As the water level rises the water flows into the secondary chamber dropper pipe, but the heavier sediments remain.
  3. Once the water reaches the correct water level it begins to flow into the dropper tube and into the secondary chamber.
  4. The water is then forced through the coalesce filter and through the flow directory due to the hydraulic passive flow of the water. The water is filtered through the processes of adsorption, attachment and interception to remove unwanted nutrients as well as any contaminants that enter the system. As the water level rises the heavier oils and hydrocarbons remain on the top of the water, unable to enter the coalesce filter due to their density.
  5. The water then rises up the riser flow director tube as the overall water level rises, into the bypass chamber and then flows out of the discharge tube. The height of the bypass inlet and the outlet tube have a difference of 150mm, hence if the system is under normal flow conditions, there is no bypass used and all water is filtered.

Features of StormProtector

  • Coalesce Filtration – Designed to reduce contaminate to 5mg/L
  • Settlement chamber – capture of all fine and coarse sediment from entering secondary chamber
  • Bypass – resumes full flow of water during high flow conditions
  • Coalesce Filter Guiderails to provide easy removal of filter for maintenance and service
  • Flame Dip Inlet
  • Automatic closure device to prevent contaminants from discharging into waterways and shutting off flow in high percentage of oil and hydrocarbon pollution
  • Passive hydraulic system so will remain fully functioning in power failure situations
  • Ease of Maintenance
  • Underground Installation
  • Automatic alarm and monitoring system
  • Configuration Range – The StormProtector has a wide range of sizes, inlet sizes, flow rates and possible filtration rates to suit any demand of any site
  • Offline Bypass – This design feature has the bypass system stored outside of the body of the StormProtector , in the form of a bypass box with a weir which has a maximum height greater than that of the maximum water level of the StormProtector.

PROTEC WATER products are Quality Assured under BS EN ISO 9001:2000 – manufactured in a modern manufacturing plant ensuring the highest standard of quality control. Protector separators are filament wound by an advanced, patented, chop hoop filament winding process. This process produces not only circumferential strength as found in helical wound tanks, but also high longitudinal strength. The interlaminar shear strength permits tanks to be cut for manholes and pipework without undue loss in strength.

The dished ends are incorporated during the filament winding process, enabling tanks to be moulded and completed as virtually ‘one piece’ units. The manufacturing process is carefully monitored with a digital read out system. Chopping glass, winding glass, the resin-rich inner layer and main laminate resins are kept within specification parameters, thus minimising human error. Quality control procedures require each tank to be carefully inspected and tested.

All of the Protector range have been individually engineered to handle the toughest environmental situations and proven in the toughest environments such as high-water tables and volcanic soils. Problems in these areas have been solved with the installation of the StormProtector.

The Packaged StormProtectors are engineered to the following Standards:BS4994 – 1987, AS/NZS 1546.1:1998. Hydraulic and civil engineering can also be provided to your requirements.

Installation of StormProtector

The installation of the StormProtector follows a simple process. A complete installation hand book is supplied to ensure the installation goes smoothly and to plan. The guide provides advice for lifting, OHS measures, handling techniques and other important requirements. Installation is typically:

  1. Excavate an area for positioning with suitable easy placing of the tank and filling as well as for consolidating concrete for backfilling.
  2. Lifting and handling of the system must use appropriate processes. More details can be found in the Manual. All lifting apparatus (cables, straps, chains etc.) must be provided by a contractor.
  3. Installation can be conducted with or without appropriately designed feet for the product, each with their own following installation instruction details found in the Installation Manual.
  4. The system can be secured in several ways including Pea gravel and concrete surrounds, stabilised sand surroundings, concrete base and concrete surround, pea gravel backfill, mechanical anchoring etc. All have been clearly outlined in the installation manual provide by Protector.
  5. Allow for protection of inlets/discharge points/vents to be supervised by contractor. Connect each suitably designed fitting with the desired location for completion.
