Exploring GHG emissions in the mainstream SCEPPHAR configuration during wastewater resource recovery

The wastewater sector paradigm is shifting from wastewater treatment to resource recovery. In addition, concerns regarding sustainability during the operation have increased.

In addition, concerns regarding sustainability during the operation have increased.

This study assesses the nitrous oxide and methane emissions during the long-term operation of a novel wastewater resource recovery facility (WRRF) configuration: the mainstream SCEPPHAR.

Intermittent aeration was the aeration strategy that most mitigated the NO emissions in the nitrifying reactor, obtaining a reduction of 40 % compared to the normal operation of the pilot plant. 22022-01-0120222022-01-01Articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://ddd.uab.cat/record/265727https://dx.doi.org/urn:doi:10.1016/j.scitotenv.2022.157626reponame:Dipòsit Digital de Documents de la UABinstname:Universitat Autònoma de BarcelonaInglésengAgència de Gestió d'Ajuts Universitaris i de Recerca https://doi.org/10.13039/501100003030 2017/SGR-1175Agència de Gestió d'Ajuts Universitaris i de Recerca https://doi.org/10.13039/501100003030 2017/SGR-1318European Commission https://doi.org/10.13039/501100000780 690323open accesshttp://purl.org/coar/access_right/c_abf2Aquest document està subjecte a una llicència d'ús Creative Commons.
