PORTLAND, Maine, April 20, 2016 /PRNewswire/ -- The First Defense® High Capacity, an advanced hydrodynamic separator for stormwater treatment from Hydro International has now been certified for 50% Total Suspended Solids (TSS) removal by the New Jersey Department of Environmental Protection (NJDEP) – at the highest treatment loading rate in the industry. This advancement offers engineers and contractors the potential to save 40% more space on their site, helping to significantly reduce time and overall project costs.

First Defense® High Capacity doesn't just save space, it's also a highly adaptable online treatment system that works easily with large pipes, multiple inlet pipes, inlet grates and now contains a high capacity internal bypass for the conveyance of large peak flows. Designed with site flexibility in mind, First Defense® High Capacity allows engineers to maximize available site space without compromising treatment level.

"We've been designing advanced separation devices for decades but we've finally uncovered the secret to getting the highest loading rate through the smallest footprint," said John Larson, Senior Project Engineer at Hydro International. "This system will be an important treatment option for any engineer needing to get the most out of a small and/or difficult site space."

Systems are available in the following sizes and approved flow rates:

4ft - approved for up to 1.50/cfs
6ft - approved for up to 3.38/cfs
8ft - approved for up to 6.00/cfs

For the convenience of specifying engineers who may need assistance in selecting an appropriate model size, the online sizing calculator enables effective configuration and sizing selections based on site-specific information entered by the user. Register here to use the online sizing tool.

Engineers in New Jersey and any municipality following NJDEP regulations will now be permitted to specify a treatment system that is quickly gaining favor among engineers across North America. First Defense® High Capacity is an enhanced version of the original First Defense® which is currently installed in thousands of locations throughout the US and Canada.
