WEF Highlights

The Water Environment Federation (WEF; Alexandria, Va.) has released a fact sheet describing the treatment of pulp-and-paper-industry wastewater. The majority of the industry’s wastewater is treated using large basins, but temperature can change their performance. In this document, WEF presents details behind two commonly used, basin thermal models to compare their strengths and weaknesses as […]

Learn about biosolids applied to land in Land Application of Biosolids: Human Health Risk Assessment Related to Microconstituents, a new fact sheet by the Water Environment Federation (WEF; Alexandria, Va.) Residuals Biosolids Committee. The Sustainable Residuals Use Subcommittee developed the fact sheet to identify uses for biosolids and risks associated with land application. It describes […]

Key information about anaerobic digestion now is available in a new 6-page, open-access fact sheet prepared by the Fundamental Outreach Subcommittee of the Water Environment Federation (WEF; Alexandria, Va.) Municipal Resource Recovery Design Committee. “Anaerobic Digestion Fundamentals” provides an overview of anaerobic digestion; covers the topics of process, design, and operation and maintenance; and describes […]

The Water Environment Federation (WEF; Alexandria, Va.) Collection Systems Committee has released the fact sheet, “Sanitary Sewer Systems: Rainfall-Derived Inflow and Infiltration Modeling.” Rainfall-derived infiltration and inflow (RDII) is a known cause of sanitary sewer overflows. RDII simulation models help characterize system wet weather responses, evaluate needs, and predict performance within infiltration and inflow reduction […]
