Filterra®

The Filterra® System is a high-flow bio-filtration/retention technology. It has been optimised for high volume/flow treatment and high pollutant removal. Its small footprint allows it to be used on highly developed sites such as landscaped areas, parking lots and streetscapes.

Stormwater runoff enters the Filterra System through an inlet and flows through the specially designed filter media prior to discharging to waterways.

The filter media captures and immobilises pollutants; those pollutants are then decomposed, volatilised and incorporated into the biomass of the Filterra system’s micro/macro flora and fauna. Stormwater runoff flows through the media and into an underdrain manifold at the bottom of the system.

How Filterra Works

Stormwater runoff enters the Filterra system through a kerb-inlet opening or pipe and flows through a specially designed filter media mixture contained in a landscaped concrete container. The filter media captures and immobilises pollutants; those pollutants are then decomposed, volatilised and incorporated into the biomass of the Filterra system’s micro/macro flora and fauna. Stormwater runoff flows through the media and into an underdrain system at the bottom of the container, where the treated water is discharged.

Filterra Media - Proven Pollutant Removal

At the heart of all Filterra systems is Filterra engineered bio-filtration media; a specified gradation of washed aggregate and organic material homogeneously blended under strict quality-controlled conditions. The filter media has been optimised to operate under high flow rates (up to 3550mm/hour) while maintaining pollutant removal performance. Filterra media is tested for hydraulic functionality, fertility and particle size distribution to ensure uniform performance.
