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

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

Опубликована: Июль 16, 2024

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.

Frontiers of Environmental Science & Engineering, Год журнала: 2024, Номер 18(7)

Опубликована: Март 25, 2024

Abstract Wastewater treatment plants are the major energy consumers and significant sources of greenhouse gas emissions, among which biological nitrogen removal wastewater is an important contributor to carbon emissions. However, traditional heterotrophic denitrification still has problems excessive residual sludge requirement external sources. Consequently, development innovative low-carbon nitrate technologies necessary. This review outlines key roles sulfur autotrophic hydrogen in treatment. The discovered nitrate/nitrite dependent anaerobic methane oxidation enables sustainable emission reduction by utilizing available situ . Photosynthetic microorganisms exhibited a promising potential achieve carbon-negative removal. Specifically, algal-bacterial symbiosis system photogranules offer effective prospective options for Then, emerging technology photoelectrotrophic underlying photoelectron transfer mechanisms discussed. Finally, we summarize prospect these technologies, highlighting that solar-driven area future guiding significance design systems.
