The XTREAMFILTER is designed to filter stormwater run off and remove a large proportion of the contaminants in the process. This filtration device to be implemented into stormwater systems to remove fine sediments, heavy metals and phosphorus from stormwater runoff. The system consists of a base with several legs stands, each designed with water inlets holes to ensure high even flow of water into the water filter, a removable top shell with retention chamber, a one way air valve to create a vacuum for continuous flow and the filter cylinder itself. The water is able to evenly flow up the outer channels and flow evenly through the filter media, consisting of three different media that is designed to target and remove specific contaminants. This system is able to effectively remove large portions of sediment, gross pollutants, hydrocarbons and oils, heavy metals, nutrients and organic substances and phosphorus. This system combines to create an exceptional all round filtration system suitable for almost any site demand.

The filter is also able to come in any number of filters, in any number of arrangements to suit your site needs and provide the perfect filtration system for your need. Maintenance and installation is also simple as the system comes pre-assembled in our long life, high strength FRP horizontal encasings to provide quick and easy installation. Our filters are also easily deconstructed and the filter media is easily cleaned and maintained.

The XTREAMFILTER is one of protectors most efficient and complete tertiary treatment filters, removing high percentages of sedimentation, gross pollutants, hydrocarbons and oils, heavy metals, nutrients and organic substances and phosphorus. The process of this filter is simple, but extremely effective:

  1. Firstly the water enters through the flame dip tube from the stormwater drain or previous stormwater treatment stage and into the XTREAMFILTER housing.
  2. If equipped with a specially designed PROTECTOR FRP horizontal storage tank to house the filters, sedimentation will occur in the silt containment area prior to the filters. The raised platform for the filters provides a silt baffle to prevent sediment from entering the filters causing clogging and maintenance.
  3. Once the water level is high enough the water enters through the inlet legs, rising evenly through the base. As the water level rises the outer riser channels fill covering the surface of the filter media.
  4. The stormwater then asses through a 2mm wire mesh, removing all contaminants larger than this mesh will allow.
  5. The water then flows through the three circular cylinder layers of filtration media, as shown by the orange, green and blue in the image below. Each media is separated by a 1mm wire mesh, providing further interception
  6. After the water passes completely through the filter media, it passes through a final 1.6mm mesh and into the central riser tube.
  7. The water proceeds to fill the entire filter shell and into the top retention chamber where the water continues to fill to the height of the dropper tube and air valve. Once the water reaches this height, the one way air valve is closed and a vacuum is created inside the filter ensuring flow even if the water level drops below the filter level. The retention chamber also provides a volume for backwashing once the siphon is broke
  8. The water then flows out the central dropper tube and into the following pipe arrangements and into the final chamber of the FRP casing and then out of the tertiary treatment system and into the following waterway.


  • Adsorption
  • Interception and attachment techniques
  • Sedimentation
  • Oil and hydrocarbon capture
  • Gross pollutant trap
  • Bypass – Able to retain flow through system in the event of high flow situations, still providing sedimentation and gross pollutant trap processes.
  • Backwashing – Upon vacuum siphon break, the system backwashes, cleaning the system, reducing maintenance frequency and standing water risks.
  • Passive Hydraulic Operation – ensures function in the event of power failure
  • Wide range of configurations – System easily allows for design in multiple filter arrangements in combination, hence able to suit any site demands
  • Three layers of filtration media
  • Retention and storage Chamber


  • Car Parks and Shopping Centres
  • Council Depots
  • Industrial Estates
  • Depot and Loading Bays
  • Highways and Tunnels
  • Airports and Tarmacs
  • Retrofitting to existing Stormwater Drainage systems
  • Waste Transfer Depots


  • Car parks
  • Shopping Centres
  • Industrial and commercial estates
  • Transport Depots and Loading bays
  • Tunnels and high traffic areas
  • Airports and Tarmacs

Due to the Modular Cartridge design, the sizing options for the XtreamFilter and the simple connectivity of multiple Filters, a large range of arrangements can be configured for any need. Combined this with the high surface area and high flow capacity, the XtreamProtector range can be inserted into any specific locale or any flow rate requirement. Whether deployed singularly into manholes, or in a large arrangement, the XtreamFilter will suit any need.

Housing options are also widely available to choose from, whether deployed with our effectively designed FRP tanks, in concrete casings with a large number of filters, or singularly in manholes or precast vaults, the XtreamProtector is the filtration system for you.

The FRP tank installation follows the same basic process as the installation of our Hydraprotector range and Maxiprotector Range. As the system comes pre-assembled, the installation is simple, fast and easy. A downloadable document with further information on this can be provided on request.

The installation details for the concrete casing Installations are detailed below.

Maintenance Procedure Outline

  1. Remove the cover and open
  2. Before entering the system make sure the air is safe per OSHA Standards or use a breathing apparatus. Use low O2, high CO, or other applicable warning devices per regulatory requirements
  3. Using a vacuum truck remove any liquid and sediments that can be removed prior to entry
  4. Using a small lift or the boom of the vacuum truck, remove the used filter by lifting them out
  5. Remove the top lid by undoing the eye bolts that run through the body of the system and remove top shell.
  6. As the Filter media itself comes as a single assembled piece,
  7. Clean the Riser pipes and channel pipes, inspect, and reinstall the filter into position
  8. Remove the old filter and replace with a fresh filter in the same position
