The Biofiltration Knowledge Base is the result of a Water Research Foundation project that cataloged and summarized the design,
operation, and monitoring strategies and experiences of North American biofiltration facilities. This dynamic, user-friendly tool aids water utilities in
the evaluation of biofiltration as a viable and proven approach for drinking water treatment. The Knowledge Base communicates information and direction to
the user about (1) the benefits of biofiltration, (2) mitigating negative impacts, (3) solutions for improving initial design and operations of biofiltration
facilities, and (4) opportunities for future research.
