DENVER — Water Research Foundation recently completed a research project that resulted in a guidance manual describing and evaluating current biological filtration (BF) monitoring and control techniques, according to a press release.
The project, “A Monitoring and Control Toolbox for Biological Filtration” (Project #4231), will help water utilities improve their understanding of monitoring and controlling biological filtration (BF), which is an affordable and effective but not commonly used water treatment process, the release reported.
BF can reduce multiple contaminants and increase the biological stability in distribution systems while minimizing the production of waste streams and the formation of disinfection by-products, noted the release.
"Biological filtration can play a key role in helping water utilities meet the increasing demand for high-quality water," explained Rob Renner, executive director of WRF. "While BF has been in use for decades, its adoption in North America has been fairly limited. This research project provides a comprehensive collection of information and tools to help the water community understand and apply related best practices."
According to the release, the perception that BF is most suitable for wastewater treatment instead of drinking water treatment and the lack of industry-accepted BF design, operations and treatment guidelines and monitoring and control tools has led to BF being underutilized in North America in drinking water utilities.
