What is the BioProtector?

The Bio Protector is a combination of two effective treatment processes i.e. physical filtration process and a biological filtration process. This system is engineered to combine these two processes to form a complete and effective process to remove a large range of contaminants. The entire system uses the hydraulic flow of the stormwater to push the water through our dual filtration process. The system is easily applied into a large range of applications, including streetscapes, parking areas, urban environments, highways and industrial settings in a compact form. This system has a small footprint on its installation environment allowing it to be easily installed into any situation or in combination with a range of other Protector products, even suitable for installation downstream of detention systems, making it the only biofilter capable of this.

The Process

The system works in a very basic process, but to high effect. The stormwater enters the Storm protector system through an inlet grate, with the position of the system being placed in a high catchment area. The water initially flows through Protector Filter in an initial capture chamber. The water builds up around the filtration, and using the processes of adsorption and retention, the first stage of the system removes sediment, gross pollutants and larger contaminants. The water then flows into our bioretention media where it removes pollutants, hydrocarbons, phosphorus, heavy metals, bacteria and other contaminants through immobilisation and capturing. These pollutants, nutrients and the other contaminants are then decomposed or volatilised and become incorporated into the bioretention filter. This process also allows the removal of oils, as the oils and water separate during the process, and due to density differences, rise out of the water flow system. The water then enters the flow pipes which are all incorporated with minuscule holes for the water to flow through and then is carried into the final capture area. From this the treated water is discharged into the stormwater system that is already in place, to be moved to onwards.


Ease of combination with other protector products. As the BioProtector system is a tertiary treatment system, it can be used in conjunction with the primary and secondary treatment solutions protector has available to provide a complete system. Especially in conjunction with the EcoProtector, a gross pollutant trap, to remove the larger debris that would other wise cause clogging and increased maintenance on the BIOPROTECTOR.


With the most competitive prices with the highest quality, we offer the most cost-effective system for a long lasting and effective product


Can be used in a wide range of configurations being commercial, residential, urban or industrial.
Aesthetically suitable

Our design can easily improve and camouflage into any urban setting, whilst still fulfilling its requirements as a filtration system. The organic look that is provided by the bio protector allows an aesthetical ease into any environment.

Versatile for all areas
Our Product is ideal for both retrofitting into already existing urban settings or easily installed into new construction sites.

Filtration Techniques
The dual process of the Bioretention and the filtration media ensure FRP designs will strive to keep our streams, waterways and our environment clean.

Ease of installation and maintenance
The maintenance process is a simple process, with no requirements of entering the body of the Bioprotector.

High Flow Bypass

A high quality advantage of the BioProtector system is its efficient bypass system in the case of high flow storm conditions. The system has a simply designed bypass system to allow for overflow of storm water around the bioretention system and filter in case of high water flow rates. This system however does not filter out the contaminants as the regular flow system would but has an oil and hydrocarbon trap system to ensure that these contaminants are removed. After the case of high storms, the system should be check and maintenance may nee to be conducted.



Due to the BIOPROTECTORS large variation in installation configurations, as shall be depicted in this document, it can be placed in a wide range of settings such as:

  • Urban Settings
  • Residential
  • Commercial
  • Industrial

The system is mainly suited to areas of that have run off of fine particulates, dissolved organic materials and nutrients and heavy metal runoff

  1. Inlet into Pre-treatment chamber which acts as a capture chamber prior to the first stage of treatment, also acts as a sediment capture area and settling chamber for trash, litter and gross pollutants.
  2. Manway access for maintenance and adjustment of the Coalescer unit. This can also form the location of the Grate for the grate type inlet configuration. High flow Bypass is also present in this area, located at the highest point on each side wall of the pre-treatment chamber. This water bypasses the bioretention system in situations of high flow.
  3. Coalesce Filter and Flow director- Provides treatment of the stormwater by physically and chemical removing heavy metals, nutrients, TSS and bacteria.
  4. Bioretention Media combines the filtration methods of bioretention and filtration to remove majority of physical, chemical and biological contaminants.
  5. Water Flow Pipe which directs clean water from the bioretention and filtration processes into the discharge chamber.
  6. Water bioretention inlet pipe with miniscule perforations for water absorption to be directed into the flow pipe (5) to then be directed out. This water has been filtered by all the processes available and will be able to be returned into the water systems, clean and unpolluted.
  7. Plant system for both aesthetic and bioretention purposes.
  8. Bioretention outflow Chamber.
  9. Outlet discharge, can be combined with valve system for flow control.
  10. Outlet Chamber Manway Access for maintenance.

The Installation of the BioProtector 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.

  1. Contact Protector Engineering department and supply BioProtector location for appropriate sizing recommendations.
  2. Excavate an area for placement according to the guidelines required for the BioProtector system. It is of the responsibility of the contractor to provide optimal inlet and outlet protection prior to final installation. Ensure the area follows the guidelines to ensure maximum water capture, downstream from detention.
  3. Unload the tank from delivery system, with all lifting apparatus to be provided by contractor (cables, chains, straps etc.)
  4. Place the FRP Bioprotector system into the excavated whole, explicitly with enough room for installation and backfill.
  5. Seal the BioProtector from the construction sediment.
  6. Install system as per the system design; curb, downfall grate, Vaulted inlet, rooftop downpipe.
  7. Select Vegetation covers dependant on climate conditions of installation location.

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 BioProtector.

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