Quantification and Modelling of Fugitive Greenhouse Gas Emissions from Urban Water Systems

IWA Publishing eBooks, Journal Year: 2022, Volume and Issue: unknown

Published: April 9, 2022

Abstract With increased commitment from the international community to reduce greenhouse gas (GHG) emissions all sectors in accordance with Paris Agreement, water sector has never felt pressure it is now under transition a low-carbon management model. This requires reducing GHG grid-energy consumption (Scope 2 emissions), which straightforward; however, also Scope 1 emissions, include nitrous oxide and methane predominantly wastewater handling treatment. The pathways factors leading biological formation are highly complex site-specific. Good emission for estimating lacking, utilities have little experience directly measuring these mathematical modelling of challenging. Therefore, this book aims help address by breaking down their influencing factors, providing guidance on both use performing direct measurements sewers treatment plants. dives into predicting provides different models based upon your conditions, as well an introduction alternative methods, including metabolic, data-driven, AI methods. Finally, includes using tools assessing operating strategies identifying promising mitigation actions. A must-have anyone needing understand, account for, utility emissions.

Comparative Metagenomic and Metatranscriptomic Analyses Reveal the Functional Species and Metabolic Characteristics of an Enriched Denitratation Community

Environmental Science & Technology, Journal Year: 2020, Volume and Issue: 54(22), P. 14312 - 14321

Published: Oct. 29, 2020

Nitrite supply for mainstream anammox via denitratation has attracted increasing attention. The functional species responsible and their metabolic characteristics were unravelled in this study. A highly stable community was enriched from activated sludge by combined control of C/N pH. accumulation nitrate removal efficiencies both higher than 80% during long-term operation (>100 d). genotypic complete denitrifier Thauera aminoaromatica MZ1T identified to be mainly acetate consumption, polyhydroxybutyrate (PHB) accumulation, reduction. presence restricted the transcription electron allocation downstream denitrifying enzymes due low expression transport modules (cytochrome bc1 cytochrome c). Metabolic reconstruction strain indicated that reducing power generated tricarboxylic acid (TCA) cycle provided PHB synthesis reduction exogenous feast phase. After depletion acetate, degraded then entered TCA cycle, providing This strategy with priority given carbon storage instead nitrite might favor survival oligotrophic weak alkaline habitats. These results updated our understanding causes underlying its physiological benefits.
