Resources Environment and Sustainability, Год журнала: 2022, Номер 11, С. 100101 - 100101

Опубликована: Дек. 7, 2022

PAHs are largely spread in the aquatic environment, and drawbacks of conventional remediation techniques as well expenditures for alternative disposal polluted sediments lead to seek more effective, environmentally-friendly sustainable approaches. Therefore, present review shows a critical overview literature evaluated with VOSviewer, focusing on problem PAH-contaminated marine knowledge available processes shed light what research technology lack. This supplies specific information about key factors affecting biological, physical-chemical thermal techniques, carefully examines associated their employment remediating PAH-polluted by showing adequate alternatives. The technologies thoroughly discussed here biostimulation, bioaugmentation, sediment washing, carbonaceous adsorbent addition desorption. environmental economic impacts application mentioned have been also taken into account. Finally, this new directions future recommendations.

Innovation in decarbonizing wastewater treatment is urgent response to global climate change. The practical implementation of anaerobic ammonium oxidation (anammox) treating domestic the key reconciling carbon-neutral management with sustainable development. Nitrite availability prerequisite anammox reaction, but how achieve robust nitrite supply and accumulation for mainstream systems remains elusive. This work presents a state-of-the-art review on recent advances anammox, paying special attention available pathways (forward-going (from nitrite) backward-going nitrate nitrite)), controlling strategies, physiological ecological characteristics functional microorganisms involved supply. First, we comprehensively assessed nitrite-oxidizing bacteria control methods, outlining that these technologies are transitioning possessing multiple selective pressures (such as intermittent aeration membrane-aerated biological reactor), integrating side stream free ammonia/free nitrous acid suppression recirculated sludge treatment), maintaining high activity ammonia-oxidizing competing oxygen bacteria. We then highlight emerging strategies supply, including production driven by novel microbes (ammonia-oxidizing archaea complete ammonia bacteria) reduction (partial denitrification nitrate-dependent methane oxidation). resources requirement different analyzed, hybrid pathway combining partial nitrification encouraged. Moreover, data-driven modeling process well proactive microbiome proposed hope achieving application. Finally, existing challenges further perspectives highlighted, i.e., investigation nitrite-supplying bacteria, scaling-up from laboratory under real conditions, stable performance fundamental insights this aim inspire advance our understanding about provide robustly shed light important obstacles warranting settlement.

Quorum Quenching in Membrane Bioreactors for Fouling Retardation: Complexity Provides Opportunities

Environmental Science & Technology, Год журнала: 2024, Номер unknown

The occurrence of biofouling restricts the widespread application membrane bioreactors (MBRs) in wastewater treatment. Regulation quorum sensing (QS) is a promising approach to control MBRs, yet underlying mechanisms are complex and remain be illustrated. A fundamental understanding relationship between QS MBRs lacking, which hampers development quenching (QQ) techniques (QQMBRs). While many QQ microorganisms have been isolated thus far, critical criteria for selecting desirable still missing. Furthermore, there inconsistent results regarding lifecycle effects on physicochemical characteristics microbial communities mixed liquor assemblages QQMBRs, might result unreliable inefficient applications. This review aims comprehensively summarize timely research highlight important often ignored perspectives MBRs. We consider what this "information" can cannot tell us explore its values addressing specific questions QQMBRs. Herein, we first examine current analytical methods signals discuss roles fouling-forming cornerstones technologies. To achieve targeting strategies propose substrate specificity degradation capability surface area pore structures media as select functional microbes media, respectively. validate retardation efficiency, further specify properties, community composition, succession Finally, provide scale-up considerations QQMBRs terms debated lifecycle, practical synergistic strategies, potential cost savings presents limitations classic QS/QQ hypotheses advances role development/retardation builds bridge understandings applications technology.

Optimizing Bioaugmentation for Pharmaceutical Stabilization of Sewage Sludge: A Study on Short-Term Composting Under Real Conditions

Journal of Fungi, Год журнала: 2025, Номер 11(1), С. 67 - 67

Опубликована: Янв. 16, 2025

A significant concentration of pharmaceuticals has been detected within composted sewage sludge. Their uncomplete removal and lack monitoring during composting neglects their potentially toxic effects when used as a soil organic amendment. Previously, we successfully implemented bioaugmentation–composting system focused on toxicity pharmaceuticals’ reduction. This method, however, comprised long inoculant-acclimatization period, making it an unprofitable technology. Hence, this work aimed to explore shorter yet effective process by simultaneously implementing the inoculation native microbial consortium fungus Penicillium oxalicum XD 3.1 in piles sludge olive prunings. All were subjected frequent inoculation, windrow turning, physicochemical biological parameters. Additionally, both bioaugmentation stability degradation evaluated through different analysis rates calculations. One hundred days earlier than previous attempts, treatments achieved adequate conditions, maintained core populations while improving degrading diversity, around 70–72% pharmaceutical remotion. Nevertheless, only produced favorable results ideal for amendments (acute microtoxicity phytotoxicity). Thus, but equally stable with P. was here.
