1. The steps to Stormwater Treatment

There are three main stages to stormwater treatment and management. All three systems when combined form a complex but efficient treatment system that is able to remove almost all contaminants and pollutants, both physical or dissolved.

3. How do I size a Gross Pollutant trap

The selection of a gross pollutant trap is vital for the continued successful operation of the stormwater management system and can often be confusing and difficult. There are a wide range of reasons and considerations to determine that correct gross pollutant trap for your site. Important considerations must be taken when deciding on which Protector product is suitable for your needs. With the assistance of experienced staff we can offer endless assistance and advice in this matter. The most important aspects we consider to help solve your needs are…

5. Why would I need to install a Gross Pollutant trap?

Installation of Gross pollutant traps are vital to the protection of our environment and the continued efficient operation of all following treatment systems. In locations and sites where the production and interference of larger waste such as leaves, plastics, bottles, plastic bags and other waste products exists the use of a gross pollutant trap is vital….

7. What process is best for removing hydrocarbons from Stormwater?

Hydrocarbons make up a large majority of the pollutants present in water, being produced from fueling stations, cars and motor vehicles and in industrial processes. If these hydrocarbons flow into the stormwater systems through surface runoff they must be treated efficiently and completely…

9. Why do we treat stormwater?

Storm water is water that is produced from rain, and possibly melting snow and ice, which flows over solid surfaces, capturing gross pollutants, sedimentation, nutrients, heavy metals and a wide range of other pollutants. The majority of this water infiltrates into the soil, or evaporated or run off and enter nearby waterways. In natural areas, free from construction, buildings, motorways and agriculture etc. the water just soaks and absorbs into the soil or evaporates. In developed areas, not only does the range and concentrations of pollutants grow and grow, but the areas in which the water is usually absorbed or evaporated is removed, the storm water is funneled through stormwater drainage systems and directly into our rivers, streams and waterways.

11. What process is best for treating stormwater runoff from a highway?

There isn’t one single process that best removes a certain contaminant. To best tackle the removal of pollutants, a wide range of techniques need to be used in conjunction with each other to ensure the most effective removal possible. High traffic areas have a series of pollutants that remain a big issue in treatment of these systems. High traffic areas produce contaminants such as high amounts of hydrocarbons, high levels of gross pollutants, heavy metals and fine sedimentation. Hence solutions are required…

13. Which filter Media’s are recommended for attached and dissolved pollutant material?

There are several possible solutions to the removal of dissolved pollutants and attached contaminants. Physical filtration processes such as screening, hydrodynamic separation and physical filtration processes are unable to remove the dissolved pollutants, and hence media with chemical removal filtration methods have been found to do so…

15. What is FRP (Fibre reinforced Polymers)?

FRP, known as Fibre Reinforced Polymers or Fibre reinforced Plastics, is a composite material made up of two parts – the polymer matrix which is then reinforced with fibres…

17. So why all the fuss about FRP (Fibre reinforced polymers)

Fibre reinforced polymers are such highly sought after materials, and a growing day by day. Their applications are endless due to their wide range of advantages and benefits.

19. Battle of the Plastics – FRP (Fibre reinforced polymers) vs HDPE

HDPE, or high density polyethylene is a petroleum based thermoplastic with a high strength to weight ratio. It is often comparable to FRP as they are both plastic based materials with altered properties…

2. What is a Gross Pollutant Trap?

Gross pollutants traps are filtration systems that are designed to prevent stormwater pollution from entering the waterways. They are usually designed to catch the larger trash and debris as well as silt and larger sedimentation. The processes used in gross pollutants traps aren’t usually complex, utilising physical removal processes such as physical screening, rapid sedimentation and various separation processes such as hydrodynamic separation. They are usually designed to remove particles larger than 5mm.

4. Does a Gross Pollutant trap collect oil?

Gross pollutant traps are not able to perform any form of chemical or biological filtration processes. This means that more complex dissolved pollutants aren’t able to be removed. The physical filtration methods that exist in the gross pollutant traps are not able to remove particles dissociated within the stormwater…

6. How to clean a Gross Pollutant trap?

The maintenance procedure for a gross pollutant trap – THE ECOPROTECTOR – is fairly simple. A necessary requirement of the use of the Gross pollutant trap is the need for regular inspection, maintenance and cleaning. This regularity is defined by the catchment area that it is located in and the features and properties of the surroundings…

8. What is the best process to remove Zinc From Stormwater

The levels of Zinc in stormwater runoff has been regulated and benchmarks have been set for the zinc levels allowed. Zinc can be produced from a wide range of areas including galvanized roofs and surfaces, motor oils, wear debris from tires, atmospheric deposition and fertilizers. There are a wide range of processes that are designed to remove Zinc from stormwater…

10. What process is best for treating stormwater runoff from a carpark?

When considering what are the best processes for treating stormwater runoff in a certain application, it is vital to consider the various forms of contaminants that are produced in these areas, as well as the environment in which the application is to be placed in. Carparks developments, have the tendency for high levels of oils, gross pollutants from high foot traffic, hydrocarbons and heavy metals produced from cars ad rooftops…

12. What is the difference between physical filtration and biodegradation?

The process of physical filtration is the mechanical and physical removal of solids or fluids from a fluid through forcing the flow of the filtered liquid through a medium. This process is most simply described by the use of a medium having perforations smaller than the size of the particles in which are being endeavored to be removed…

14. What makes a Efficient Stormwater treatment system?

Several things are vital in the construction of an effective and efficient stormwater treatment system. Firstly, the system needs to encapsulate all process required for the site in which the runoff is being produced. This means careful considerations of the surrounding environment and its specifications which include…

16. What are the common uses of FRP?

FRP’s most common uses are in applications where its best properties are vital in the system use. FRP as an overall material is…

18. The Match UP – FRP (Fibre reinforced Polymers) vs. Steel

Steel is a material that is widely used in almost all areas of engineering – in infrastructure, industrial, mechanical, civil applications. It has high strength and is a very reliable material, so why would we replace the modern applications of steel with the Fibre reinforced polymer materials we have available to us today…

20. FRP (Fibre reinforced Polymers) vs. Concrete

For many years, Concrete has remained the favourite choice in civil systems due to a wide range of characteristics. Similarly to FRP,concrete is a composite material composed of a fine and coarse aggregate bonded together with a fluid cement that hardens over time
