Hydro International filter achieves field certification

Feb. 16, 2015

PORTLAND, Maine — The Final Field Certification improves upon the Interim Certification first issued by the New Jersey Department of Environmental Protection (NJDEP) in December 2009.

PORTLAND, Maine — Hydro International announced the Hydro Up-Flo® Filter, following a year of stormwater field testing, has achieved “Final Field Certification” from the New Jersey Department of Environmental Protection (NJDEP) after demonstrating pollutant removal that met or exceeded the Technology Acceptance Reciprocity Partnership (TARP) field testing protocol requirements, according to a press release.

The Final Field Certification improves upon the Interim Certification first issued by NJDEP in December 2009, stated the release.

The release reported that the Final Field Certification’s conditions allow the Up-Flo Filter with CPZ Mix™ filter media to be used to treat up to 25 gpm (0.056 cfs) per filter module with a maximum inflow area of 0.66 acres per filter module.

The field testing was conducted on the filter’s installation along the Tuscaloosa Riverwalk located in Tuscaloosa, Alabama, an area known for clayey soils and strong rainfalls, and overall, the Up-Flow Filter demonstrated 98 percent removal of all suspended sediment, 89 percent removal of total suspended solids (TSS) and 81 percent removal of suspended sediment with a mean particle size of 29 microns, continued the release.

The University of Alabama’s Civil, Construction and Environmental Engineering (CCEE) department conducted the sampling and analysis independently, noted the release.
