9 Things You Might Not Know About the Aqua-Filter Stormwater Filtration System

7/23/2015

2 Comments

 
Picture
We know our audience is well educated about stormwater filtration systems, when regulation calls for them, and how they should be used and installed. But every year at trade shows and lunch and learn presentations, we are surprised to find out how many engineers don’t know about some benefits offered by the Aqua-Filter. 
Here are a few to check out.

1.     If it’s installed in the USA, it’s built in the USA. That’s right; the Aqua-Filter is built at home, as close to the installation state as possible. This allows us to deliver the product faster and more cost efficiently.

2.     Installing the Aqua-Filter doesn’t require a crane. The modular construction and lightweight but durable materials mean skipping the high cost of a crane.

3.     As a bonus, the installation doesn’t require special sealants for piping connections.

4.     Each unit includes lifting supports and stub-outs for the inlet and outlet piping to allow for quick and simple connections.

5.     A dual process, with vortex separation removing larger pollutants prior to the water reaching the filtration chamber, extends the life of the filter media and reduces maintenance requirements.

6.     Independent validation should always be considered. Options include the new Total Phosphorus Removal Credit from the Virginia Department of Environmental Quality, along with NJDEP certification and NJCAT verification. The Aqua-Filter has independent field test verification and total Phosphorus Removal Credit from Virginia.

7.     What storage is included for sediment? What about oil and debris? This number can help you consider the long-term cost of maintenance. The Aqua-Filter has sediment storage of up to 310 ft3 and oil and debris storage up to 1,900 gallons.

8.     The Aqua-Filter works with the only EPA registered filter media for stormwater treatment. PathShield filter media offers a new approach to water treatment by killing bacteria when it comes into contact with filter media granules. The filter media is stable, non-toxic, not consumed, non-corrosive, requires no power source to kill bacteria, and is not affected by temperature changes. 

9.     The Aqua-Filter can be customized to work with your project. You can start with our project and system design tool at or call us to speak with our experienced, technical team of experts.

Hydrodynamic Separators Improve Low Impact Development Practices

6/18/2015

1 Comment

 
The Hydrodynamic Separator is like a trusted Ford pickup, reliable and easy to maintain. Like a dependable Ford, the Hydrodynamic Separator (HDS) might seem a bit dull next to the shiny new low impact development (LID) practices, but in reality, this equipment is essential to a well-rounded LID plan.

LID practices have dramatically expanded. They focus on landscape-based and water retention designs that reduce runoff volume and mimic predevelopment hydrology to meet goals of runoff reduction and water quality treatment close to the runoff source. Plus regulations often reward developers for infiltration and/or rainwater harvesting. Regulatory agencies also recognize the added value of HDS for upstream protection of sensitive LID practices. Too often HDS has been relegated to traditional, end-of-pipe solutions. Not so fast! Hydrodynamic separators play an important role in developing a treatment train that is essential to the long-term success of LID practices, including infiltration, harvesting, bioretention and storage.

At first a combined approach using HDS can seem counterintuitive to LID, it’s actually a comprehensive, long-term solution that can address problems before they start. Over time, this treatment train approach can reduce the long-term harmful buildup of particles, dirt and trash within LID facilities. For example, one Chattanooga, Tennessee customer embraced this idea and used an HDS to pretreat runoff for an underground rainwater harvesting structure used for surface infiltration landscaping irrigation, toilet flushing, and even a decorative fountain on top of both structures.

As you can see from this example, the best of both a traditional and progressive approach can improve aesthetics, reduce maintenance time and costs for the facility, increase the entire system lifecycle, all the while enhancing property equity to maximize land use from that of a conventional stormwater management approach.

First Bahrain Project Using Aqua-Swirl Opens to the Public

4/29/2015

3 Comments

The first Aqua-Swirl in Bahrain was installed in the parking lot of the now iconic Four Seasons Hotel.  Bahrain Bay is the Kingdom of Bahrain’s first master planned mixed-use waterfront community, situated off the northeast coast of the capital Manama. The $2.5 billion development has a masterplan designed to create a fusion of residential, commercial, retail, tourism, and community facilities and public amenities.

The engineering wonder is built on a reclaimed island in the center of Bahrain Bay.

The project included two Aqua-Swirl AS-6s to return clean water to the bay and reduce flooding. Though rainfall is scarce, large amounts of rain tend to fall at once, creating runoff and often flooding. Having a solution that allows for high water flows was essential. The Aqua-Swirl treats flows up to 178L/s.

“Service is extremely important for this client, so ensuring that runoff doesn’t collect on the car lots was a high priority. No one wants cars flooded at this high-rise,” said Sellam Hmadouch, Aqua-Shield’s Middle-East representative.

AquaShield Presents Low Impact Development Practices at Chattanooga Engineers Club

3/17/2015

0 Comments

 
One of the leading topics in stormwater management today is the drive for sustainability, green infrastructure designs and Low Impact Development (LID) practices.

Mark Miller, research scientist for AquaShield, Inc., presented trends in LID and changing stormwater regulations in Chattanooga at the Engineers Club. Mark offered an overview of the topics and discussed the movement toward water catchment versus end of pipe solutions.

Key takeaways included:

  • Storage is important, but pretreatment is the first key to the success of a storage based LID plan
  • When picking an LID plan, consider the benefits of each. Pick the best possible solution for the problem at hand based on your goals. 
  • Maintenance is essential and must be considered on the front end. Poor upkeep can subtract from the benefits of a progressive LID plan.

  • Biofiltration helps groundwater recharge and reduces the heat island effect.

There is no single solution for stormwater management. This makes multiple technologies needed to solve problems. Solutions can include, media filtration, surface and subsurface infiltration, treatment and storage, rain harvesting, drivable grass and many more.
