Nutrient Separating Baffle Box® (NSBB®)

An advanced multi-stage stormwater runoff treatment system

The Nutrient Separating Baffle Box® (NSBB™) is an advanced multi-stage stormwater runoff treatment system. The patented screen system is designed to capture and store debris in a dry state to minimize nutrient leaching, allowing for easier maintenance. The triple chamber design enables a high-level removal of TSS over a range of particle sizes and is effective in capturing both nutrients and hydrocarbons.

A patented deflector system ensures no sediment scouring occurs during high flows, allowing for online installation without needing separate diversion structures.

With the addition of a SkimBoss® MAX or Floating Skimmer, the NSBB™ can further amplify the effects of the already included Hydro-Variant Technology®, bolstering pollutant capture potential, detention time, and balancing conveyance with flow rate. The NSBB™ is a widely accepted treatment solution among civil engineers, developers , and municipalities.

• Filtering is provided by the screen system basket, suspended above static water level, which has a capacity of several cubic yards depending on the model. The function of the screen basket is to capture gross solids like trash, foliage, and debris.
• Sediment separation is facilitated by three settling chambers with a capacity of several cubic yards each depending on the model. These chambers collect smaller sediments and particulate metals.
• StormBooms™ attached to the influent side of the skimmer removes floating and emulsified hydrocarbons from the water.

Benefits of The Nutrient Separating Baffle Box®

• Fits within existing easements
• Retrofits existing watersheds
• Patented screens maximize storage and prevent debris loss
• Rainwater harvesting and wet or dry detention
• Dry-state storage separates debris from water and sediment
• Water will not turn septic
• Easy vacuum truck servicing
• Full capture for trash TMDL’s
• Captures foliage, litter, sediment, phosphates, hydrocarbons… Everything!
• Turbulence deflectors prevent captured sediment from re-suspending
• Hydrocarbons collect in front of the skimmer and are absorbed by Storm Boom
