A flare efficiency estimator (FEE) tool is part of Water Environment Research Foundation (WERF) project U2R08 entitled Methane Evolution from Wastewater Treatment and Conveyance under WERF’s Climate Change Program and funding from the New York State Energy Development Authority (NYSERDA). The FEE is based on the work of the Flare Research Group at the University of Alberta (UoA) and it will help estimate the fugitive greenhouse gas (CH4) emissions from the unprotected ‘candlestick’ flares for digester gas and landfill gas flares.

Identification of Barriers to Energy Efficiency and Solutions to Promote These Practices
Successful deployment of energy efficiency initiatives may be increased by recognizing barriers and advancing strategies that overcome them. A national survey recently collected input on barriers...
Methane Evolution from Lagoons and Ponds
These case studies focus on the CH4 emissions from wastewater treatment in photosynthetic oxidation ponds and facultative sludge lagoons. These area-intensive processes are for cryophilic-to-...
N2O and CH4 Emission from Wastewater Collection and Treatment Systems: State of the Science Report and Technical Report
In a world where there is a growing awareness of the possible effects of human activities on climate change, there is a need to identify the emission of greenhouse gases (GHG) from wastewater...
Current Energy Position of New York State Wastewater Treatment Facilities
In 2008, the New York State Energy Research and Development Authority (NYSERDA) published the “Statewide Assessment of Energy Use by the Municipal Water and Wastewater Sector” documenting 2003/...
Solids Role in Tertiary Chemical Phosphorus Removal by Alum
The need to control and remove phosphorus (P) in discharges from wastewater treatment facilities (WWTF) to prevent eutrophication of receiving waters is well known. Regulatory initiatives are...
Sensor Technology for Water Quality Monitoring: Fiber Optic Sensor
Two methods for the detection of important human pathogens, Cryptosporidium parvum and Helicobacter pylori, were investigated: a fiber optic biosensor, and real time PCR. The mechanism for...
Public Communication: Perceptions and Early Communications Tools
Public understanding leading to support for investment in aging water infrastructure is absolutely essential in order to close the “gap” between projected and current funding levels. In response...
Identification of the ‘Active’ Fraction and Metabolic Pathways in Trace Organic Contaminants Removal Using Stable Isotope Probing
The widespread presence of trace organic contaminants (TOrC), such as the endocrine disrupting compound bisphenol-A (BPA), has been cause for growing concern due to persistence in the environment...
A Novel Membrane Process for Autotrophic Denitrification
Biological denitrification by heterotrophic bacteria is common in the wastewater industry in the U.S. and in drinking water processing in Europe. To facilitate heterotrophic...
Safe Piped Water
The factors affecting the presence and growth of micro-organisms in piped networks are reviewed in this book, as are the practices of water supply organisations that can directly or indirectly...
Technical Approaches for Setting Site-Specific Nutrient Criteria
The purpose of this project was to develop a methodology for deriving site-specific nutrient criteria (SSNC) for surface waters, including streams and rivers, lakes and reservoirs, and coastal...
Bioavailability and Characteristics of Dissolved Organic Nutrients in Wastewater Effluents
This study aims to investigate and assess:
1) the bioavailability of various P fractions, particularly dissolved P fractions (DOP), in advanced wastewater effluents
2) the nature and...
