SBBGR technology for reducing waste sludge production during plastic recycling process: Assessment of potential increase in sludge hazardousness

Valerio Guido Altieri et al.

Summary: This study evaluated an unconventional approach for treating wastewater generated from the cleaning of non-hazardous plastic solid waste during the plastic recycling process. The proposed scheme was based on sequencing batch biofilter granular reactor (SBBGR) technology, which showed remarkable removal efficiencies and a sludge production six-fold lower than the conventional plant. The SBBGR technology also did not result in a significant increase in the concentration of hazardous compounds in the sludge.

Rapid formation of aerobic granular sludge by bioaugmentation technology: A review

Xushen Han et al.

Summary: This review summarizes the main strategies for accelerating the formation of aerobic granular sludge (AGS) and focuses on the bioaugmentation technology. The bioaugmentation technology is divided into two categories: flocculating bacteria and filamentous fungus, which includes pure fungal pellets and pellet-bacteria system. The review also discusses the adsorption of various microorganisms by pure-culture fungal pellets in long-term operation. A comparison analysis of different bioaugmentation technologies for rapid AGS cultivation is provided, along with prospects for future research.

Effect of different forms and components of EPS on sludge aggregation during granulation process of aerobic granular sludge

Ting Peng et al.

Summary: This study investigated the characteristics of three forms of extracellular polymeric substances (EPS) and their component proteins (PN) and polysaccharides (PS) during the granulation process of aerobic granular sludge (AGS) and their effects on the aggregation performance of AGS. The results showed that tightly bound EPS (TB-EPS) played a critical role in the formation of AGS, with PN being the major contributor to promoting the formation of AGS and enhancing its aggregation performance.

Analysis of the microbiota associated with the blackening of activated sludge

Xiaowu Huang et al.

Summary: This study utilized 16S rRNA gene amplicon sequencing to reveal the microbial community composition and dynamics of activated sludge experiencing blackening, uncovering a previously unknown diverse sulfide producing microbial community with metabolic versatility. The findings suggest a broad role of these generalist microorganisms in regulating ecological sulfur-nitrogen-carbon transformation. This research provides in-depth understanding of the biochemical reactions responsible for sludge blackening and inspires novel research focuses on microbial-driven sulfur-nitrogen-carbon cycle.

Shedding Light on Microbial Dark Matter: Insights Into Novel Cloacimonadota and Omnitrophota From an Antarctic Lake

Timothy J. Williams et al.

Summary: Through genomic analysis, novel metabolic traits of Candidatus bacterial phyla Cloacimonadota and Omnitrophota have been identified, including carbon fixation using reverse tricarboxylic acid cycle, and strong biosynthetic capacity for organic compounds. Both taxa are inferred to form metabolic interactions with hydrogen-consuming partners in Ace Lake, occupying specific niches.
