Nutrient Separating Baffle Box (NSBB)

The Nutrient Separating Baffle Box (NSBB) is an advanced vault treatment system for storm water runoff. Its patented screen system is designed to capture and store debris in a dry state to minimize nutrient leaching and allow for easy servicing. The NSBB’s triple chamber design affords high TSS removal over a wide range of particle sizes, while patented deflectors ensure no sediment scouring occurs during high flows. This allows for on-line installation without the need for separate diversion structures. The NSBB is a widely accepted storm water treatment BMP among developers, civil engineers and municipalities nationwide.
