By using MCF 0.165, CH 4 emissions from domestic wastewater were around 28 Mt CO 2 eq in 2014 in Du et al. 7 While Yan et al. 11 obtained that the estimated CH 4 emissions were 0.77 Mt CO 2 eq in ...
Energy performance assessment of a WWTP should account for both energy consumption and energy generation in different stages. Wastewater contains energy in different forms such as organic carbon and nutrients, as shown in Fig. 2 (Gude 2015a, 2016), which can be extracted through various integrated biological (Zhang et al. 2019; …

Comparison of the WWTP effluent data from Young et al. (2009) with data collected from other WWTPs in different parts of the United States and France (Colman, 2002; Gruau et al., 2005) shows that δ 18 O PO 4 values within the effluent from a single plant can vary by at least 3.9‰ for samples collected 3 months apart, and samples from ...
1 . Wastewater treatment plant. A wastewater treatment plant (WWTP), receives and treats municipal and industrial wastewater. That is, a WWTP treats water to remove waste, grease and floating oils, sand and any coarse debris present in the water; the treatments remove organic and inorganic materials through settling processes, as well as biodegradable …

As an example, Panepinto et al. (2016) in a thorough study on Turin WWTP energy efficiency, used four KPIs (energy per person equivalent, per m 3 of water, per kg of COD removed and per kg of N removed) as, in effect, one KPI may not fully reflect the purpose of the plant. A WWTP could have multiple functions, e.g. removing COD, …
