Up-Flo Filter Verified by TARP Partner
Hydro International of Portland, Maine, on Nov. 13 announced a significant technology validation for the Hydro Up-Flo® Filter, an advanced stormwater filtration device.
The New Jersey Corporation for Advanced Technology (NJCAT), a public-private partnership, verified the stormwater treatment performance capabilities of the Up-Flo Filter, which employs upflow technology to capture trash and debris and filter fine particulate matter from stormwater runoff. NJCAT works closely with The Technology Acceptance and Reciprocity Partnership (TARP), formed by eight states to evaluate and share scientific data on technology performance of environmental protection solutions. By sharing data and standardizing testing methods, TARP aims to help agencies streamline approval processes and contractors make informed purchasing decisions.
NJCAT verified that the Up-Flo Filter removes more than 80 percent total suspended solids using Hydro-Filter-Sand™ media. Laboratory test protocols and equipment were designed to mimic real field installations by using the full-scale commercially available filter, having up to six filter modules housed in a 4-foot diameter structure. No other filter device verification has undergone testing that demonstrates filter performance based on multiple filter modules operating at peak filtration flow rates.
Requiring only 20 inches of driving head, the verified loading rate of the filter was an unprecedented 18.2 gallons per minute per cubic foot (gpm/ft2) compared to conventional filters that typically operate around 2 gpm/ ft2. Pursuant to the verification under TARP's laboratory protocols, the filter is undergoing additional performance verification under the TARP Tier II testing protocols.
TARP member states are California, Massachusetts, Illinois, Maryland, New York, Pennsylvania, Virginia, and New Jersey. Other regions such as the metropolitan areas of Atlanta and Nashville also look to TARP guidelines for guidance on new stormwater management technologies.
"We're thrilled to receive this designation from NJCAT, which is respected for its stringent level of oversight in stormwater management," said David Mongeau, general manager at Hydro International's U.S. Stormwater business. "NJCAT's close connections with TARP will help engineering consultants in New Jersey and in states as far away as California understand the Up-Flo Filter's benefits and how they can be leveraged during the stormwater permitting process required for development and redevelopment construction."
The filter removes trash, sediments, nutrients, metals, and hydrocarbons from stormwater runoff. As the industry's only fluidized bed upflow filtration technology, it provides a higher level of treatment, a higher rate of filtration, longer life of filter media and a longer maintenance cycle than other filter systems.
