Nutrient Separating Baffle Box

The 2nd generation Baffle Box design removes sediment, foliage and litter without head loss. It separates nutrients from stormwater and prevents bacterial build-up. Sediments settle to the bottom. The box can be made of either concrete construction or fiberlass in any size. In addition, it easily retrofits to existing pipe and is easy to clean.

Schematic Drawing - During Storm Event The inflow pipe is the same size as the ouflow. Turbulence deflectors prevent captured sediment from re-suspending. Hydrocarbons collect in front of skimmer and are absorbed by Storm Boom.

Schematic Drawing - After Storm Event Nutrient pollutant load is not lost to static water and flushed out at the next storm event. Separating organic matter from the static water prevents bacterial buildup. To view installation photos of Nutrient Separating Baffle Boxes - CLICK HERE.

Size Determination

Because the entire flow is always treated and head loss is so minimal, determining the appropriate size of Nutrient Separating Baffle Box for a project is more an element of pipe size than treated cfs.

• Because water flow is not ducted off line for treatment, head loss is minimal and comparable to a large square catchbasin. Because of this, existing stormwater systems can be retrofitted with a Nutrient Separating Baffle Box, without compromising the original design specifications of the existing stormwater system.
  
  
• All structures are load rated for at least H-20. Standard wall construction of the structure is 6" thick steel re-enforced concrete. Concrete wall thickness can be thicker upon request.
  
  
• Manhold lids, hatches, and dampers to block off water flow during servicing can be incorporated into the structure.
  
  
• Screen systems have stainless steel screens bolted into a heavy duty aluminum framework. The screen systems are hinged to give easy access to the lower chambers and have a wide range of adjustments to accommodate unforeseen variables during installation.
