Our Objective

WERF will identify, assess, and make recommendations to improve sustainable wastewater nutrient removal and recovery technologies. WERF will provide information to help agencies meet receiving water body requirements and other wastewater treatment goals, such as climate change, sustainability, cost-effectiveness, and reliability. The research will inform regulatory decision making, and help practitioners comply with increasingly high levels of nitrogen and phosphorus removal, with a focus on improving plant performance.

Preview of Nutrients Compendium Report Provides Greenhouse Gas Emissions Guidance
WERF is providing a preview of the Biological Nutrient Removal and Greenhouse Gases Compendium, which provides municipal wastewater treatment facilities with new information on potential green house gas emissions from wastewater treatment.

The Latest WERF Nutrients Research Featured at WEFTEC 2010
This WERF-sponsored workshop will discuss the principles and the state of the knowledge of supplement of carbon sources for supporting/enhancing denitrification.

The Science of N & P Regulations: A Web Seminar for Florida Utilities
(Subscriber only) This special web seminar on June 8, 2010, focused on Florida's pending numeric nutrient criteria. Speakers included JB Neethling and David Clark, both of HDR, Inc., principal investigators under contract to perform research directed by WERF.

Collaborating with the Chesapeake Bay Program STAC
WERF co-sponsored the EPA Chesapeake Bay Program Scientific and Technical Advisory Committee (STAC) meeting on effluent organic nitrogen in September 2007. WERF collaborated again in a May 2008 workshop, which provided useful information about the benefits of advanced wastewater treatment facilities in reducing nutrients and emerging contaminants.

Nutrients in Chesapeake Bay
The U.S. Fish & Wildlife Service offers a definition of nutrients and information about how nutrients enter the Bay and how to correct the problem.
