To understand the physical and biological processes in a high-rate biofiltration system, it’s necessary to look at how each system component contributes to

High-rate biofiltration differs from traditional bioretention in that it has been optimized for high volume/flow treatment and high pollutant removal.

High-flow bioretention systems target the removal of suspended solids, total and dissolved nutrients and metals, oil and grease, trash, and debris. Components

High rate biofiltration continues to gain acceptance within the regulatory and engineering community as an acceptable alternative to traditional bioretention.

Contech has published several blog posts that refer to corrugated metal pipe (CMP) for underground storage of stormwater. We were a bit surprised when some
