All rights reserved. Version_0419 Floatable trash & debris in the Aqua-Swirl® Aqua-Swirl® XCelerator Stormwater Treatment System The Aqua-Swirl® XCelerator Stormwater Treatment System (Aqua-Swirl® XCelerator) is a vortex-type hydrodynamic separator designed and supplied by AquaShieldTM, Inc. (AquaShieldTM). Aqua-Swirl® XCelerator technology removes pollutants including suspended solids, debris, and floatables from stormwater runoff. Both treatment and storage are accomplished in the single swirl chamber without the use of multiple or hidden, blind access chambers. System Operation The treatment operation begins when stormwater enters the Aqua-Swirl® XCelerator through a tangential inlet pipe that produces a circular (or vortex) flow pattern that causes contaminates to settle to the base of the unit. Since stormwater flow is intermittent by nature, the Aqua-Swirl® XCelerator retains water between storm events providing both dynamic and quiescent settling of solids. The dynamic settling occurs during each storm event while the quiescent settling takes place between successive storms. A combination of gravitational and hydrodynamic drag forces encourages the solids to drop out of the flow and migrate to the center of the chamber where velocities are the lowest. © AquaShieldTM, Inc. 2019. All rights reserved. Version_0419 Aqua-Swirl® XCelerator System Maintenance The long term performance of any stormwater treatment structure, including manufactured or land based systems, depends on a consistent maintenance plan. Inspection and maintenance functions are simple and easy for the Aqua-Swirl® XCelerator allowing all inspections to be performed from the surface. It is important that a routine inspection and maintenance program be established for each unit based on: (a) the volume or load of the contaminants of concern, (b) the frequency of releases of contaminants at the facility or location, and (c) the nature of the area being drained. In order to ensure that our systems are being maintained properly, AquaShieldTM offers a maintenance solution to all of our customers. We will arrange to have maintenance performed. Inspection The Aqua-Swirl® XCelerator can be inspected from the surface, eliminating the need to enter the system to determine when cleanout should be performed. In most cases, AquaShieldTM recommends a quarterly inspection during construction and for the first year of operation to develop an appropriate schedule of maintenance. The Aqua-Swirl® XCelerator should be inspected and cleaned at the end of construction regardless of whether it has reached its sediment storage capacity and/or other captured materials. Based on experience of the system’s first year in operation, we recommend that the inspection schedule be revised to reflect the site-specific conditions encountered. Typically, the inspection schedule for subsequent years is once per year. Maintenance The Aqua-Swirl® XCelerator has been designed to minimize and simplify the inspection and maintenance process. The single chamber system can be inspected and maintained entirely from the surface thereby eliminating the need for confined space entry. Furthermore, the entire structure (specifically, the floor) is accessible for visual inspection from the surface. There are no areas of the structure that are blocked from visual inspection or periodic cleaning. Inspection of any floatable debris can be directly observed and maintained through the manhole access provided directly over the swirl chamber. Inspection Procedure To inspect the Aqua-Swirl® XCelerator, a hook is typically needed to remove the manhole cover. AquaShieldTM provides a customized manhole cover with our distinctive logo to make it easy for maintenance crews to locate the system in the field. We also provide a permanent metal © AquaShieldTM, Inc. 2019. All rights reserved. Version_0419 Sediment inspection using a stadia rod information plate affixed inside the access riser which provides our contact information, the Aqua-Swirl® XCelerator model size, and serial number. The only tools needed to inspect the Aqua-Swirl® XCelerator system are a flashlight and a measuring device such as a stadia rod or pole. Given the easy and direct accessibility provided, floating trash and debris can be observed directly from the surface. Sediment depths can easily be determined by lowering a measuring device to the top of the sediment pile and to the surface of the water. AquaShieldTM recommends that the units be cleaned when sediment depth reaches 6 inches, representing 50% sediment storage capacity. The full sediment storage depth in the Aqua-Swirl® XCelerator is 12 inches. It should be noted that in order to avoid underestimating the volume of sediment in the chamber, the measuring device must be carefully lowered to the top of the sediment pile. Keep in mind that the finer sediment at the top of the pile may offer less resistance to the measuring device than the larger particles which typically occur deeper within the sediment pile. Aqua-Swirl® XCelerator Cleanout Procedure Cleaning the Aqua-Swirl® XCelerator is simple and quick. Floatable trash debris can be observed and removed directly through the 30-inch service access riser provided. A vacuum truck is typically used to remove the accumulated sediment and debris. An advantage of the Aqua-Swirl® XCelerator design is that the entire sediment storage area can be reached with a vacuum hose from the surface reaching all the sides. Since there are no multiple or limited (blind) access chambers in the Aqua-Swirl® XCelerator there are no restrictions to impede on-site maintenance tasks. -48” © AquaShieldTM, Inc. 2019. All rights reserved. Version_0419 Vacuum (vactor) truck quickly cleans the single open access swirl chamber Disposal of Recovered Materials AquaShieldTM recommends that all maintenance activities be performed in accordance with appropriate health and safety practices for the tasks and equipment being used. AquaShieldTM also recommends that all materials removed from the Aqua-Swirl® XCelerator and any external structures (e.g, bypass features) be handled and disposed in full accordance with any applicable local and state requirements.

Floatable Trash and Debris 1. Remove manhole lid to expose liquid surface of the Aqua-Swirl® XCelerator. 2. Remove floatable debris with basket or net if any present. II. Sediment Accumulation 1. Lower measuring device (e.g. stadia rod) into swirl chamber through service access provided until top of sediment pile is reached. 2. Record distance to top of sediment pile from top of standing water: inches. 3. Maximum recommended sediment depth prior to cleanout is 12 inches for all models. Consult system shop drawing for treatment chamber depth as measured from the inlet pipe invert to base of the unit. III. Diversion Structures (External Bypass Features) If a diversion (external bypass) configuration is present, it should be inspected as follows: 1. Inspect weir or other bypass feature for structural decay or damage. Weirs are more susceptible to damage than off-set piping and should be checked to confirm that they are not crumbling (concrete or brick) or decaying (steel). 2. Inspect diversion structure and bypass piping for signs of structural damage or blockage from debris or sediment accumulation. 3. When feasible, measure elevations on diversion weir or piping to ensure it is consistent with site plan designs. © AquaShieldTM, Inc. 2019. All rights reserved. Version_0419 4. Inspect downstream (convergence) structure(s) for sign of blockage or structural failure as noted above. CLEANING Schedule cleaning with local vactor company or AquaShieldTM to remove sediment, trash, and other floatable pollutants. The captured material generally does not require special treatment or handling for disposal. Site-specific conditions or the presence of known contaminants may necessitate that appropriate actions be taken to clean and dispose of materials captured and retained by the Aqua-Swirl® XCelerator. All cleaning activities should be performed in accordance with property health and safety procedures. AquaShieldTM always recommends that all materials removed from the Aqua-Swirl® XCelerator during the maintenance process be handled and disposed in accordance with local and state environmental or other regulatory requirements. MAINTENANCE SCHEDULE I. During Construction Inspect the Aqua-Swirl® XCelerator every three (3) months and clean the system as needed. The Aqua-Swirl® XCelerator should be inspected and cleaned at the end of construction regardless of whether it has reached its maintenance trigger. II. First Year Post-Construction Inspect the unit(s) every three (3) months and clean the system as needed. Inspect and clean the system once annually regardless of whether it has reached its sediment or floatable pollutant storage capacity. III. Second and Subsequent Years Post-Construction If the system did not reach full sediment or floatable pollutant capacity in the First Year Post-Construction period, the system can be inspected and cleaned once annually. If the Aqua-Swirl® XCelerator reached full sediment or floatable pollutant capacity in less than 12 months in the First Year Post-Construction period, the system should be inspected once every six (6) months and cleaned as needed. The unit should be cleaned annually regardless of whether it reaches its sediment or floatable pollutant capacity. IV. Bypass Structures Bypass structures should be inspected whenever the Aqua-Swirl® XCelerator is inspected. Maintenance should be performed on bypass structures as needed. © AquaShieldTM, Inc. 2019.
