Biological filtration has a long history of use in drinking water treatment, starting with slow sand filtration in the early 1900s. Over the last 15+ years, considerable research has been done to advance the science and engineering of surface water biofiltration. Specifically, WRF projects have focused on documenting perceptions, experiences, and current practices associated with biofiltration; converting conventional filters to biofilters; biofiltration monitoring, tracking, and control strategies; enhancing biofiltration; and multicontaminant removal through biofiltration.

A significant need exists in the industry to develop a central reference, a Biofiltration Handbook, for the design, operation, monitoring, conversion and optimization of biofiltration, which is the ultimate objective of this project. The handbook will facilitate the implementation of biological filtration as an effective engineered process rather than an incidental process operated on an ad hoc basis.
