Nutrient Separating Baffle Box®
High Volume Separator
Nutrient Separating Baffle Box® High Volume Separator is a highly recognized storm water treatment system that utilizes a patented screening technology, enhanced three chamber separation, and inline installation. The system’s inline design eliminates the need for diversion structures, creating more cost savings. The NSBB’s triple compartment scour-free design and screening system captures sediment and suspends trash and debris in a dry state. Dry state storage greatly minimizes nutrient leaching, bacteria growth, and odors leading to improved water quality for the surrounding water bodies. Longterm maintenance of a stormwater BMP will eventually outweigh the initial cost. Storing waste solids in a dry state suspended in the basket minimizes maintenance costs by eliminating the need to remove thousands of gallons of water during the cleaning process. The Result Studies and historical performance data shows that a Nutrient Separating Baffle Box treating wet-weather flows will remove 86.9% of the total suspended solids, 47% of bacteria, and 99% of oils and grease.
The patented screening system suspended above the sedimentation chambers, captures and stores trash and debris in a dry state. Dry state storage of trash and debris minimizes nutrient leaching, bacterial growth, bad odors, and allows for an easier removal.
During Storm Events
Filtration Screen – Collects and Stores Trash, Debris, Organics, and Oxygen Demanding Substances Above Standing Water in a Dry State.
Turbulence Deflectors – Prevents Re-suspension of Captured Pollutants.
Trash, debris, and organics are captured in the filtration screen as sediments settle to the bottom chambers. Hydrocarbons are removed and absorbed by the boom.
Between Storm Events
Sediment Chambers – Maximizes TSS Removal and Eliminates Scouring During Extreme Flow Rates.
Skimmer & Boom – Collects Hydrocarbons and Controls Flow Velocity which Improves Removal Efficiency.
Trash, debris, and organics are stored in a suspended screen system allowing pollutants to dry out between storm events. This eliminates septic conditions and prevents leaching of plant-based organics into water.
Pre-treatment and diversion eliminate the need for a separate diversion structure. The NSBB’s patented deflector shield system allows the system to be installed inline and provides the unique advantage of providing both pre-treatment and low flow diversion for above ground and underground infiltration basins.
