Aqua-Filter Stormwater Filtration System

Water Quality Treatment Process

1. Runoff flows into the Aqua-Swirl, which provides pretreatment through the physical settling of particles.

2. Floating contaminants such as trash, oil, and grease are detained by an internal baffle in the Aqua-Swirl.

3. Water flows under the baffle and into the Aqua-Filter.

4. Once in the Aqua-Filter, the stormwater flows through pores in the perlite filter cartridges, which provides physical and chemical treatment that removes suspended sediments and other associated contaminants. Over time, the filtration media clogs—slowing down the infiltration rate—and the perlite cartridges must be replaced.

5. Treated runoff is channeled through an outlet pipe to the surface.
