Summary: Anaerobic membrane bioreactors (AnMBRs) are a promising technology for water reuse, but there is currently fragmented evidence for their potential and efficacy in this regard. This article reviews the latest developments in municipal wastewater treatment using AnMBRs and evaluates their potential application for water reuse. The findings suggest that, under stable operation, AnMBRs can produce water suitable for agricultural reuse. However, without post-treatment, AnMBRs cannot meet non-potable reuse standards across important parameters such as COD, BOD5, NH3-N, and TP. The analysis of key operational parameters provides insights into the operation of AnMBRs for non-potable reuse, including influent water matrix, pH, temperature, hydraulic retention time, system, and membrane configuration. An assessment of post-treatment technologies highlights a tradeoff between cost and effluent quality based on the specific reuse requirements. The article concludes by discussing the challenges and limitations of using AnMBRs for reuse applications and outlines a pathway to maturity for effective treatment trains.

Summary: Recently, the nitrate/nitrite-dependent anaerobic methane oxidation (n-DAMO) processes have gained significant attention in wastewater treatment. These processes not only reduce carbon emissions and enhance biological nitrogen removal but also face practical challenges due to the distinctive properties of nDAMO microorganisms and the limited availability of methane. This paper discusses the commonly-applied types of bioreactors for nDAMO-based biotechnologies and proposes key perspectives to inspire future investigation and practical applications of the n-DAMO processes.

Summary: This study demonstrates that high-COD/TOC produced water can be effectively removed with appropriate microbial inoculation, leading to energy recovery in the form of methane. Chemical analyses show that ethylacetate-extractable compounds in produced water are more amenable to biodegradation, while compounds added during drilling and completion significantly contribute to COD and anaerobic degradability.

Summary: This study focused on the treatment of PVA-containing wastewater discharged from the textile industry. The feasibility of anaerobic treatment was verified through batch experiments, and a two stage SSSABs coupled SBR scheme was proposed, which showed higher removal rates compared to other schemes. Each reactor in the process was found to play an important role, and SEM images revealed the unique microbial flora in each SSSAB. The SSSAB-SSSAB-SBR process offers an alternative to chemical methods for treating PVA-containing wastewater.

Summary: Treatment of industrial wastewaters can be challenging due to toxic and persistent compounds and unfavorable pH conditions. Extractive membrane bioreactor (EMB) is a promising technology capable of overcoming these difficulties. This review analyzes earlier PDMS and newest polymeric membrane reactors, highlighting their potentialities and research issues. Factors such as biofilm formation, reactor configuration, and operative parameters greatly affect reactor performance and further investigations are needed. Data analysis shows that this technology is ready for upscaling, which is crucial for evaluating its feasibility in industrial wastewater treatment.

Summary: The spatial distribution of microorganisms in a methane-based membrane biofilm reactor (MBfR) was experimentally revealed in this study, showing the dominance of anammox bacteria, nitrite/nitrate-dependent anaerobic methane oxidation (n-DAMO) bacteria, and n-DAMO archaea in different layers of the biofilm. It was found that microorganisms in the outer layer preferred substrates from wastewater, while those in the inner layer utilized substrates from the biofilm substratum. This study provides insights into microbial stratification in biofilm systems and potential applications of methane-based MBfRs in sewage treatment.

Summary: Partial denitrification-anammox (PdNA) technology has the potential to improve nitrogen removal efficiency and reduce costs. The study found that methanol is the preferred carbon source due to its higher PdNA efficiency and rate. However, achieving low effluent total nitrogen limits in PdNA filters primarily depends on the appropriate ratio of ammonium to NOx in the upstream activated sludge.

Summary: Two anaerobic dynamic membrane bioreactors (AnDMBRs) were operated at room temperature and mesophilic conditions to treat synthetic blackwater. The results showed that organics removal was similar between the two conditions, but methane production differed. The formation of a dense sludge filtration layer on the dynamic membrane at room temperature led to faster membrane fouling. Microbial community analysis revealed higher richness and lower diversity at room temperature, promoting the growth of certain bacteria.

Summary: This study investigated the resistance of anaerobic membrane bioreactor (AnMBR) to lipid gradients during food wastewater treatment. The results showed that AnMBR could adapt to a certain content of lipids by stimulating biomass growth and activity. However, a further increase in lipid dosage led to system failure and inhibited methane production.

Summary: Anaerobic self-forming dynamic membrane bioreactors (AnSFDMBRs) have gained attention as an alternative to conventional anaerobic membrane bioreactors (AnMBRs) due to their high flux, low fouling propensity, and cost-effectiveness. Previous studies have focused on lab-scale research to optimize performance, with microbial analysis revealing dominant bacteria phyla in bulk sludge and cake biofilm, but lower abundance in biocake. Critical reviews of AnSFDMBR fundamentals, operational conditions, and potential applications emphasize the need for future research on membrane module optimization, surface modification, and microbial enrichment to design efficient systems for diverse wastewater treatment.
