Overview 

Bioinfiltrator is a sophisticated departure from other “tree-in-a-box” bio filters because it’s not in a box. An open base is not only better for vegetation, it also allows you to keep more runoff on site while using less building material so it’s lightweight and easy to install.

Targeted Pollutants:

  • Fine and coarse particles / total suspended solids (TSS)
  • Floatable trash and debris
  • Liquid- and sediment-bound oils and hydrocarbons
  • Particulate and dissolved metals
  • Nutrients (nitrogen, phosphorous)

Applications: 

  • Bioinfiltrator reliably treats surface water runoff from impermeable surfaces including highways, parking lots, industrial areas and urban developments.
  • As part of green infrastructure, LID or LEED systems
  • Curb inlets, parking lots or parking medians
  • Urban areas where site space is limited
  • Industrial stormwater pollution control

Designed for

Metals

Nutrients

Oils & hydrocarbons

Trash & floatables

Very fine particles

Benefits
  • An open base won’t restrict root growth so vegetation thrives quicker and lives longer
  • Works with a variety of trees, shrubs and hedges or with street furniture e.g. bike racks, message boards, benches etc.
  • Modular design allows you to treat a range of drainage areas
  • Runoff is kept on site which reduces quantity of stormwater that is discharged
  • Lightweight components can ship flat and be installed with only landscape equipment - no crane needed. First tree box filter with lightweight, modular components.  (Patent pending - # 15/379223)
  • Optional internal bypass for conveyance of high flows  

 

 

How it works

1. As water flows into the storm drain, it will quickly come in contact with the flow spreading baffle wall.

2. Water will then be forced left, right and all the way around the outer pretreatment chamber (see Fig.1). This process causes the flow to slow, preventing media from being blasted into piles and avoiding an uneven treatment area.

3. Trash and coarse debris are captured and stored in the outer chamber while remaining flow enters through the baffle wall.

4. Eventually the flow seeps through the baffle wall into the interior treatment chamber. From here, finer particles and pollutants will be trapped on the top layer (3 inches or so) of engineered filter media. 5. Sediment and particulate pollutants are removed as the stormwater makes it way through the engineered filter media while dissolved pollutants will be absorbed through the root system.
