About the Aqua-Filter Stormwater Filtration System
General Information Performance Data Water Quality Treatment Process Design


The Aqua-Filter Stormwater Filtration System combines a hydrodynamic separator that provides pretreatment through sedimentation and a subsurface filtration unit that physically removes contaminants. The system performed moderately well at removing most analyzed pollutants from stormwater runoff.

About the Aqua-Filter Stormwater Filtration System

Manufactured by AquaShield, the Aqua-Filter Stormwater Filtration System is composed of two units in series: the Aqua-Swirl, a hydrodynamic separator that provides pretreatment through sedimentation, and the subsurface Aqua-Filter filtration chamber. UNHSC researchers evaluated the performance of these two components as a combined treatment train. The system demonstrated moderate water quality treatment.

Where to Use It

This system can be used in most parts of the country. Its compact subsurface design makes it especially well suited to space-constrained sites, where larger, surface systems are impractical. It is commonly used beneath parking lots, transportation structures, and in other urban settings.

Implementation

Though often used in tandem as a “treatment train,” each component of this system can be used as a stand alone device, or as a pretreatment in conjunction with other stormwater systems, depending on reglations. The Aqua-Filter Stormwater Filtration System uses an Aqua-Swirl for pretreatment. The treatment train configuration enables greatly improved performance, beyond that of a single system.

The installation cost of the Aqua-Filter Stormwater Filtration System is $31,500 per acre of runoff treated, and this does not include system maintenance.

Designs for this system are available from the manufacturer.
