TL;DR: Activated sludge and return activated sludge microbial communities from three full-scale municipal wastewater treatment plants were compared to assess the impact of sludge settling and profile microorganisms responsible for nutrient removal and reactor foaming and show that all three plants were dominated with microbes in the phyla of Proteobacteria.

TL;DR: The abundance of methanogens at the top was about four times higher than at the bottom, correlating to much higher methane production from the top verified by ex-situ biomethane assay, causing foaming, consistent with foaming potential assessment of digestate samples from the digester.

TL;DR: The results show that pH can be used as a surrogate parameter to monitor and control biogas upgrading and to improve the release of calcium is essential for the acceleration of the weathering process of steel-making slag for subsequent construction applications.

TL;DR: A three-step platform to treat ECs is developed and no enzymatic loss due to filtration and membrane adsorption was observed, suggesting the feasibility of the UF membrane for enzyme concentration.

TL;DR: In this article, the performance of C. vulgaris microalgae to simultaneously recover nutrients from sludge centrate and produce biomass in a membrane photobioreactor (MPR) was evaluated at two different nutrient loading rates.
