Morelli, B., S. Cashman, Cissy Ma, J. Garland, J. Turgeon, L. Fillmore, D. Bless, AND M. Nye. Nutrient Removal and Resource Recovery: Effect on Life Cycle Cost and Environmental Impacts of Small Scale Wastewater Treatment - Seattle. Presented at AWWA's 2018 Sustainable Water Management Conference, Seattle, WA, March 25 - 28, 2018.
Impact/Purpose:
Holistic Approaches Towards Sustainable Water Systems. A small community wastewater treatment has implemented the upgrade of the conventional activated sludge treatment process with enhanced primary settling, Modified Ludzack-Ettinger secondary treatment, and anaerobic digestion (AD). Life cycle assessment, life cycle impact assessment and cost analysis were used to evaluate the combined benefits and tradeoffs of the upgraded and the legacy systems.
