FlowFilter
SPECIALIST STORMWATER FILTRATION SYSTEM
FlowFilter is a specialist stormwater filtration system that is purpose-built to reduce the footprint of WSUD on constrained projects. Manufactured, designed, and engineered in Australia using fibre-reinforced polymer (FRP) this generational asset is supplied with a 25-year warranty & 100-year design life.
This innovative approach to stormwater treatment uses an up-flow filtration process. With minimal head drop required between inlet and outlet, these devices are suitable for installation on flat sites or low gradient developments. The stormwater is treated within the unit by the following processes: sedimentation, filtration, adsorption, and precipitation.
Features & Benefits
Effective Pollutant Removal
Proven to remove heavy metals, TSS, phosphorus, and nitrogen, tested for superior pollutant capture.
High Flow Capacity
Verified for flow rates of 4 LPS per filter cartridge, with treatment flow rates from 2.5 to 156 LPS in offline configurations.
Compact & Efficient
Reduces the footprint of WSUD on constrained projects. Requires only 250mm of hydraulic head, ideal for flat or low-gradient sites.
Durable Construction
Built with robust materials for long-lasting performance in demanding conditions. Suitable for a variety of environments, including areas with heavy traffic.
Low Maintenance
Designed for easy access and minimal servicing requirements to reduce operational costs.
Flexible Configurations
Available in both offline and custom-designed inline systems for a wide range of applications.
Retrofit Ready
Easily adaptable for use in both new developments and existing infrastructure upgrades.
