Technology Description Baffle boxes are concrete or fiberglass structures containing a series of sediment settling chambers separated by baffles. The primary function of baffle boxes is to remove sediment, suspended particles, and associated pollutants from storm water. Baffle boxes may also contain trash screens or skimmers to capture larger materials, trash, and floatables. Baffle boxes are located either in-line or at the end of storm pipes.
Limitations As with any stormwater quality treatment practice, lack of inspections and maintenance will lead to reduced performance. Factors Causing Under-Performance If the NSBB is designed and installed correctly, there is minimal possibility of failure. The system will be designed to convey stormwater up to the maximum flow rate of the storm sewer system. There are no moving parts to bind or break, nor are there parts that are particularly susceptible to wear or corrosion. Lack of maintenance may cause the system to operate at a reduced efficiency, and it is possible that eventually the system will become filled with sediment in the first chamber or that the aluminum screen basket will become filled with vegetation and debris and overflow the basket and or hinder the flow, if the system is improperly maintained. When the NSBB is newly installed, frequent inspection is highly recommended. The design of the NSBB unit permits easy inspection. It is recommended that during the first two years after installation, inspection be performed at least quarterly for the purpose of noting the rate of sediment, vegetation and litter accumulation.
Safety Considerations
Verification Fact Sheet Based on the evaluation of the results from laboratory studies, sufficient data is available to support Suntree's claim. Claim - The Suntree Nutrient Separating Baffle Box, Model NSBB-3-6-72, at a treatment flow rate of 1.0 cfs (448 gpm; 24.9 gpm/ft2), has been shown to have a 67.3% suspended solids concentration (SSC) removal efficiency (as per the NJDEP methodology for calculation of treatment efficiency) using NJDEP specified material with an average d50 particle size of 63 microns, influent concentrations of 100-330 mg/L and 50% initial sediment loading in laboratory studies using simulated stormwater.
