[PMID: 39053544 DOI: 10.1016/j.scitotenv.2024.174974] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2024] [Revised: 06/27/2024] [Accepted: 07/20/2024] [Indexed: 07/27/2024]
Abstract
Recent research on the archaea community in aerobic granular sludge (AGS) has attracted considerable attention. This review summarizes the existing literature on composition, distribution, and related functions of archaea community in AGS. Furthermore, the effects of granulation, substrate, temperature, process types, and aeration models on the archaea community were discussed. Significantly, the layered structure of AGS facilitates the enrichment of archaea, including methanogenic archaea and ammonia-oxidizing archaea. Archaea engage in metabolic interactions with other microorganisms, enhancing the ecological functionalities of AGS and its tolerance to adverse conditions. Future investigations should focus on minimizing greenhouse gas emissions and exploring the roles and interactive mechanisms of archaea and other microorganisms within AGS.

Abstract
Aerobic granular sludge (AGS) technology has been recognized as a promising alternative to alleviate the osmotic stress of hypersaline wastewater. However, the response of AGS process to composite hypersaline wastewater on removal performance and populations was yet to be understood. In this work, two sequenced batch reactors were operated in parallel in absence (R0) and presence (R1) of high concentration sulfate as proxy for single and mixed salts (30 g salt·L-1) respectively. Results demonstrated that the presence of sulfate in hypersaline wastewater enhanced chemical oxygen demand (COD) and total nitrogen (TN) removals of 95.3% and 65.5% respectively with lower accumulations of nitrite. High-throughput 16 S rRNA gene sequencing technique elucidated that Denitromonas (31.6%) and Xanthomarina (17.0%) were the more dominant genera in AGS response to mixed salts with high sulfate and laid the biological basis for strengthening removal performance. The enrichment of halophilic Luteococcus (23.5%) in the AGS surface indicated the potential role of mixed salts in shaping the physical properties and surface population structure of AGS. Our work could facilitate the potential applications of AGS technology for industrial hypersaline wastewater treatment with complicated compositions.

Elevated salinity deteriorated enhanced biological phosphorus removal in an aerobic granular sludge sequencing batch reactor performing simultaneous nitrification, denitrification and phosphorus removal. JOURNAL OF HAZARDOUS MATERIALS 2020; 390:121782. [PMID: 32014652 DOI: 10.1016/j.jhazmat.2019.121782] [Citation(s) in RCA: 47] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/04/2019] [Revised: 10/27/2019] [Accepted: 11/27/2019] [Indexed: 06/10/2023]
Abstract
Hypersaline wastewater may pose threats to biological wastewater treatment processes. An aerobic granular sludge-based sequencing batch reactor (SBR) performing simultaneous nitrification, denitrification and phosphorus removal (SNDPR) was evaluated with increased salinity from 1 to 2 % (w/v). Nitrogen removal performance was unaffected by salinity up to 20 g/L in terms of reliable and efficient nitrification and denitrification. Enhanced biological phosphorus removal (EBPR) process was completely deteriorated at salinity up to 2 %, in contrast to excellent phosphorus removal at 1 %. Profiles of phosphorus over one cycle demonstrated that higher salinity not only inhibited anaerobic phosphorus release but also impeded aerobic/anoxic phosphorus uptake. Illumina MiSeq sequencing revealed multiple halophilic and non-halophilic bacteria within aerobic granules with family Anaerolineaceae being the predominant potential salt adapter. Besides, ammonia oxidizing bacteria (AOB), glycogen accumulating organisms (GAOs) were more tolerant to salt than nitrite oxidizing bacteria (NOB) and phosphorus accumulating organisms (PAOs) and denitrifying PAOs (DNPAOs). These results deciphered the resilience of aerobic granular sludge-based biological nitrogen and phosphorus removal processes to hypersaline stress.

Abstract
Seawater can be introduced or intrude in sewer systems and can thereby negatively influence biological wastewater treatment processes. Here we studied the impact of artificial seawater on the enhanced biological phosphate removal (EBPR) process performance by aerobic granular sludge (AGS) with synthetic wastewater. Process performance, granule stability and characteristics as well as microbial community of a seawater-adapted AGS system were observed. In seawater conditions strong and stable granules formed with an SVI5 of 20 mL/g and a lower abrasion coefficient than freshwater-adapted granules. Complete anaerobic uptake of acetate, anaerobic phosphate release of 59.5 ± 4.0 mg/L PO43--P (0.35 mg P/mg HAc), and an aerobic P-uptake rate of 3.1 ± 0.2 mg P/g VSS/h were achieved. The dominant phosphate accumulating organisms (PAO) were the same as for freshwater-based aerobic granular sludge systems with a very high enrichment of Ca. Accumulibacter phosphatis clade I, and complete absence of glycogen accumulating organisms. The effect of osmotic downshocks was tested by replacing influent seawater-based medium by demineralized water-based medium. A temporary decrease of the salinity in the reactor led to a decreased phosphate removal activity, while it also induced a rapid release of COD by the sludge, up to 45.5 ± 1.7 mg COD/g VSS. This is most likely attributed to the release of osmolytes by the cells. Recovery of activity was immediately after restoring the seawater feeding. This work shows that functioning of aerobic granular sludge in seawater conditions is as stable as in freshwater conditions, while past research has shown a negative effect on operation of AGS processes with NaCl-based wastewater at the same salinity as seawater.

Abstract
Efforts to produce aerobic granular sludge (AGS) for high-efficient and stable nutrient removal in high saline wastewaters have gained much attention recently. This study was undertaken to describe the phase-related characteristics of the rapid formation of glucose-fed salt-tolerant AGS (SAGS) generated from common municipal activated sludge using metagenomic approaches. The time needed for SAGS formation is about 11 days in a multi-ion matrix salinity of 3%. There were three distinct developmental phases during sludge maturation which were designated: I) the salinity adaptation phase (days 1-2), II) the particle-size transition phase (days 3-5) and III) the maturation and steady-state phase (days 6-11), respectively. Genome-based analysis revealed that during the phase I, members of the genus Mangrovibacter, which has the potential to secrete extracellular polymeric substances (EPS), dominated during the formation of initial SAGS aggregates. During phase II, fungi of the class Saccharomycetes, in particular the genus Geotrichum, became dominant and provided a matrix for bacterial attachment. This mutualistic interaction supported the rapid development and maintenance of mature SAGS. This work characterizes a robust approach for the rapid development of SAGS for efficient saline sewage treatment and provides unique insight into the granulation mechanism occurring during the development process.
