Emerging technology has been developed to capture energy present in wastewater for electricity generation through the development of microbial fuel cells. Most of the microbial fuel cell efforts have focused on energy from the carbon metabolism. Researcher will evaluate ammonia oxidation in lieu of carbon oxidation as a promising new renewable energy technology, using recent advances in nanotechnology, biotechnology, materials science. Co-digestion of Organic Waste Products with Wastewater Solids (OWSO5R07) CDM Co-digestion of organic wastes with wastewater solids is used to treat industrial, agricultural and commercial organic wastes. As a result of co-digestion, there has been an observed increase in biogas production, reduced electrical and natural gas demand, extended landfill life, reduced greenhouse gas production and a new revenue source from waste tipping fees. Currently anaerobic digester performance and operations is based on indirect measurements that include volatile solids reduction and loading rates. These indirect measurements work for wastewater solids because of the extent of empirical data on the treatment of wastewater solids. This changes when the digester feedstock is altered with other organic wastes. The development of data is essential to make co-digestion an efficient process to be implemented by municipalities. Current a Waste Characterization Protocol under development. Laboratory analysis will be underway this summer. Energy Management (OWSO6R07) SAIC A substantial amount of information exists regarding energy efficiency opportunities at wastewater treatment plants, including benchmarking studies in US and Europe. Facility level energy benchmarks are largely voluntary and implementation of these measures has progressed unevenly. While some states have energy programs that are well synchronized with their planning and design guidelines, many do not. In addition, many design guidelines suggest that facilities be planned and designed over a 20-year period which may result in over capacity and inherent energy inefficiency in the early years of operation. Value analysis is an established and often required step during planning and design phases. Value analysis practitioners are certified through SAVE International and include experts in a variety of disciplines. VA practice, as it relates to energy reduction for wastewater treatment, can be improved by incorporating energy efficiency, renewable energy production, CHP and other concepts in the model standard. This project will: • improve VE practice as it relates to energy reduction for wastewater treatment facilities; • focus on pathways to promote the VE practice with the SAVE Foundation and improve VE in regards to liquid treatment and solids handling process energy efficiency • evaluate the feasibility of establishing a national standard for VE of wastewater treatment facilities modeled after the existing ASTM Standard E-1699 or alternative (e.g., VALUE international). Characterization of Greenhouse Nitrogen Emission from Wastewater Treatment Operations Columbia University A new project just started to develop, calibrate and validate biochemical models for N2O production by autotrophic nitrification and denitrification processes to characterize nitrogen GHG emissions from wastewater treatment. Case Study of Best Practices for Sustainability CH2M-Hill GWRC Water & Energy - Draft report 64
A new project to develop parameters to define sustainability in a carbon constrained environment. Once the parameters for measurement have been developed, they will be applied at the Strass WWTP in Austria which is self-sustaining with regards to energy. This project will result in the collection of data to evaluate the process optimization decisions made at the Strass plant. Process changes made and the results that yielded the current energy sustainability will be documented in a case study. Emphasis will be made on assessing the impact to the carbon footprint of these changes for an assessment of net environmental benefit. GWRC Water & Energy - Draft report 65
