Aqua-Swirl™
As stormwater enters the Aqua-Swirl™ by means of its tangential inlet pipe and flows
across a radial baffle, a swirling (or vortex) pattern is produced within the chamber
that enhances removal efficiency of pollutants. A combination of hydrodynamic and
gravitational drag will force the floatable contaminants to migrate to the center
where velocities are lowest and allows dynamic settling of solids at the bottom of
the chamber.
Aqua-Filter™
The Aqua-Filter™ Stormwater Filtration System operates without any moving parts or
valves, which simplifies the "treatment train" process. Its small footprint and
modular design utilizes effective swirl technology of the Aqua-Swirl™ as pretreatment
in conjunction with a filtration chamber to refine or polish the stormwater over a
bed of media removing fine sediment, nutrients, petroleum hydrocarbons and heavy
metals prior to discharge into sensitive receiving waters.
Aqua-Guardian™
Surface stormwater flows into the Aqua-Guardian™ and accumulates in the sediment
chamber to begin the treatment process of capturing pollutants. As the storm
continues, water flows through a locking filter screen standpipe that disperses
over filter media where fine sediment, petroleum hydrocarbons, nutrients and heavy
metals are removed before exiting the catch basin insert through a perforated base plate.
