This PFI: AIR Technology Translation project focuses on translation of a new wastewater treatment technology to fill the wastewater nitrogen treatment technology gap. The translated technology has the following unique features: conversion of ammonia to nitrous oxide, use of nitrous oxide to oxidize methane in biogas, and enhanced recovery of energy that provides exemplary opportunities for protection of waterways from nitrogen pollution while decreasing energy usage, decreasing residual solids for disposal, and increasing energy recovery compared to the leading competing technology (conventional nitrification and denitrification) in this market space. The project accomplishes this goal by short-circuiting the conventional nitrogen removal process, converting waste ammonium to nitrous oxide and using nitrous oxide to oxidize biogas for energy recovery resulting in on-site proof-of-concept with nitrogen-rich wastewater generated during the anaerobic digestion of organic matter at leading wastewater utilities in the San Francisco Bay area. The partnership engages East Bay Municipal Utility District (Oakland, CA), South Bayside System Authority (Redwood City, CA), and Delta Diablo Sanitation District (Antioch, CA) to provide guidance in the wastewater treatment sector and other aspects: financing, commercialization, adaptation of existing infrastructure, and scale-up, as they pertain to the potential to translate the technology along a path that may result in a competitive commercial reality. The expected economic impact is $300k to $500k in annual operational savings at treatment plants that adopt the translated technology, which will contribute to the U.S. competitiveness in wastewater treatment within 3 to 5 years. The societal impact, long term, will be the development of a cost-effective technology for removal of nitrogen from wastewater, preventing fertilization of waterways and potential for formation of destructive anoxic dead zones while also creating opportunities for energy recovery, converting nitrous oxide from harmful greenhouse gas to a new source of renewable energy.

PFI：空气技术翻译项目的重点是翻译新的废水处理技术，以填补废水氮处理技术差距。翻译的技术具有以下独特特征：将氨转化为一氧化二氮，使用一氧化二氮在沼气中氧化甲烷，以及增强的能源恢复，为氮污染提供了示例性的机会，可以保护免受氮的能量使用，同时降低了与竞争性的互动率相比，可以降低用于分配的良好的固定固体，并降低了竞争性的互动率（与常规率恢复）。 The project accomplishes this goal by short-circuiting the conventional nitrogen removal process, converting waste ammonium to nitrous oxide and using nitrous oxide to oxidize biogas for energy recovery resulting in on-site proof-of-concept with nitrogen-rich wastewater generated during the anaerobic digestion of organic matter at leading wastewater utilities in the San Francisco Bay area.
