Journal ArticleDOI

Wastewater-Based Epidemiology: Global Collaborative to Maximize Contributions in the Fight Against COVID-19.

Aaron Bivins, +59 more
TL;DR: Author(s): Bivins, Aaron; North, Devin; Ahmad, Arslan; Ahmed, Warish; Alm, Eric; Been, Frederic; Bhattacharya, Prosun; Bijlsma, Lubertus; Boehm, Alexandria B; Brown, Joe; Buttiglieri, Gianluigi; Calabro, Vincenza; Carducci, Annalaura; Castiglioni, Sara; Cetecioglu Guro
Journal ArticleDOI

Anaerobic co-digestion of fat, oil, and grease (FOG): a review of gas production and process limitations.

TL;DR: A review of the literature on biogas production, inhibition, and optimal reactor configurations can be found in this article, which highlights future research needed to improve the gas production and overall efficiency of anaerobic co-digestion of FOG with biosolids from municipal wastewater treatment.
Journal ArticleDOI

Effect of spatial differences in microbial activity, pH and substrate levels on methanogenesis initiation in refuse

TL;DR: This study suggests that methanogens tolerant to low pH, such as M. barkeri, are required to overcome the low-pH, high-VFA conditions present during the anaerobic acid phase of refuse decomposition.
Journal ArticleDOI

Determining the limits of anaerobic co-digestion of thickened waste activated sludge with grease interceptor waste

TL;DR: Stepwise increases in co-substrate addition led to better microbial acclimation and reduced the GIW inhibitory effect and the results show the significant benefits of anaerobic co-digestion ofGIW and the positive impacts of gradual addition of GIW.
Journal ArticleDOI

Evidence for fat, oil, and grease (FOG) deposit formation mechanisms in sewer lines.

TL;DR: It is proposed that the formation of FOG deposits occurs from the aggregation of excess calcium compressing the double layer of free fatty acid micelles and a saponification reaction between aggregated calcium and free fatty acids.
