Aqua-Swirl | Stormwater Treatment System
Aqua-Swirl Stormwater Treatment System is a custom engineered, post-construction flow-through water quality device designed to remove coarse sediment, debris and free floating oil by utilizing hydrodynamic separation technology. Aqua-Swirl technology is a modular high flow rate treatment system that has no moving parts and operates under gravity flow conditions within a single swirl chamber.
Aqua-Swirl systems are available in the following lightweight high performance construction materials depending on project-specific location and needs.The small footprint design combined with these lightweight and durable materials, eliminates the need for heavy lifting equipment during installation.
Fabrication facilities are located in the U.S. and Canada to better serve our customers by providing cost-effective and timely logistical solutions. The Aqua-Swirl is commonly installed in an offline configuration, but is also available in a variety of configurations. Each unit includes lifting supports and stub-outs for the inlet and outlet piping to allow for quick and simple connection to the conveyance storm pipe. Inspection and maintenance activities are easily performed from the surface without the need for confined space entry or special equipment. A vacuum truck is typically used to clean the swirl chamber.
Aqua-Filter | Stormwater Filtration System
Aqua-Filter Stormwater Filtration System is a post-construction flow-through water quality device custom designed to remove fine-grained sediment, heavy metals bound to particulate matter and residual oil by utilizing a treatment train approach. AquaFilter technology incorporates a hydrodynamic separation chamber (Aqua-Swirl) for pretreatment and a separate chamber to provide filtration treatment. Aqua-Filter™ systems are available in two choices of high performance construction materials depending on project-specific needs:
The modular construction of the Aqua-Filter, combined with the use of lightweight and durable materials, eliminates the need for heavy lifting equipment during installation. Fabrication facilities are located throughout the U.S. to better serve our customers by providing cost-effective and timely logistical solutions. Aqua-Filter systems are typically installed in an offline configuration, but can be designed for inline (online) installations where allowed by local regulations. Each unit includes lifting supports and stub-outs for the inlet and outlet piping to each component which allows for quick and simple connection to the conveyance storm pipe. Inspection and maintenance activities are easily performed from the surface. A vacuum truck is typically used to perform maintenance on the swirl chamber while filter replacement requires personnel entry to the filtration chamber.
Aqua-Guardian | Catch Basin Insert
The patented Aqua-Guardian Catch Basin Insert is a post-construction flow-through water quality device custom designed to effectively remove sediment, trash & debris, heavy metals bound to particulate matter and oil. The Aqua-Guardian captures gross pollutants while simultaneously providing a high level of filtration treatment of stormwater runoff or industrial water discharges. The Aqua-Guardian uses the same types of filter media that are also used in the Aqua-Filter Stormwater Filtration System.
The most commonly used media in the Aqua-Guardian and Aqua-Filter is perlite. Other filter media such as granular activated carbon (GAC), leaf compost, zeolite and various media blends are also available for the Aqua-Guardian to meet site-specific discharge criteria. Implementing a consistent maintenance program will result in long term operational and performance efficiency for the Aqua-Guardian insert.
Bio-Filter | Stormwater Biofiltration
The AquaShield Bio-Filter Stormwater Biofiltration System is a “tree box” design that provides an innovative and sustainable green infrastructure solution to meet the growing challenges of Low Impact Development (LID) practices. The Bio-Filter is a water quality treatment device capable of removing coarse and fine sediment, trash and debris, heavy metals bound to particulate matter, as well as oil by utilizing elements of pretreatment and biofiltration. The modular unit incorporates a trash shelf at the point or entry, a pretreatment chamber for removing coarse sediment, a biofiltration chamber using engineered soil, an internal bypass for high flow conditions, and an outlet chamber prior to discharge.
Each Bio-Filter unit is constructed of lightweight and durable Polymer Coated Steel (PCS) to provide long term operational and structural functionality. Available model sizes range from 4 x 4 feet to 6 x 8 feet in area (16 to 48 square feet). The engineered biomedia can be utilized with 18 or 24 inches of depth. Each unit also includes two 15-inch diameter access ports to the trash shelf, pretreatment chamber and underdrain area to facilitate inspection and maintenance activities. A decorative metal tree grate is included for each unit. A non-skid surface material is used for the top of each unit, and on request, can also be applied to the sides of the unit. Structural integrity of each unit is leak tested at the factory prior to shipping. No heavy lifting equipment is needed for installation. Each unit is shipped with the biomedia pre-installed. It is the responsibility of the contractor to install the vegetation that is specified by others.
Independent testing of the Bio-Filter media demonstrates a high level of performance. The biomedia achieves over 90% removal of fine-grained sediment based on performance testing using the manufactured test sediment SIL-CO-SIL 106 (median particle size of 22 microns). The biomedia also attains up to 96% removal of insoluble (total) forms of copper and zinc. These effective levels of sediment and metals removal are achieved at gravity flow infiltration rates up to 135 inches per hour. Phosphorus removal is enhanced by both plant and biomedia uptake. The pretreatment chamber is based on the principle of hydrodynamic vortex separation. The internal bypass design not only allows for the elimination of an external bypass structure, but also provides for an overall reduced installation footprint and associated piping connections.
