BioHaven - Model BSB - FFSB -Streambed / Forced-Flow Stream Bed

There are two standard models:

• The BSB has a stream channel on top that allows deep water to be drawn up into it and exposed to the atmosphere. Its main purpose is aeration.
• The Forced-Flow BSB sits mostly below the waterline to promote optimal biofilm growth. The stream channel is submerged, allowing water to circulate through the matrix under pressure. The FFSB has heat-retention capabilities for increased wintertime efficacy. Its main purpose is forced circulation particularly in a wastewater environment.

Both BSBs can be anchored or tethered. The blower assembly in both systems is housed onshore.
