Hydro Intl., a provider of environmentally sustainable products and innovative solutions that control and treat storm water, wastewater and combined sewer overflows, has announced a significant technology validation for the Hydro Up-Flo filter, an advanced storm water filtration device.
The New Jersey Corporation for Advanced Technology (NJCAT), a public-private partnership, verified the storm water treatment performance capabilities of the Up-Flo filter, which employs upflow technology to capture trash and debris and filter fine particulate matter from storm water runoff. This milestone extends Hydro’s portfolio of products verified by NJCAT. The company’s Downstream Defender storm water separator was verified under the NJCAT laboratory testing protocols in 2005.
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 Up-Flo filter having up to six filter modules housed in a 4-ft-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 in. of driving head, the verified loading rate of the Up-Flo filter was an unprecedented 18.2 gal per minute (gpm) per sq ft compared to conventional filters that typically operate around 2 gpm per sq ft. Pursuant to the verification under Technology Acceptance and Reciprocity Partnership (TARP) laboratory protocols, the filter is undergoing additional performance verification under the TARP Tier II testing protocols.
“We’re thrilled to receive this designation from NJCAT, which is respected for its stringent level of oversight in storm water management,” said David Mongeau, general manager at Hydro's U.S. storm water 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 storm water permitting process required for development and redevelopment construction.”
The NJCAT designation follows the Up-Flo filter’s pilot use-level designation earlier this year by the Washington Department of Ecology, also known for its rigorous performance verification standards.
