Summary: Anaerobic wastewater treatment processes are increasingly popular due to their advantages in sludge management and net energy consumption, with methane production being a major benefit. Utilizing porous membranes for membrane contactor (MC) process offers a promising way to recover dissolved methane (dCH4) from anaerobic effluents, although membrane wetting and fouling remain implementation challenges. The development of wetting- and fouling-resistant hollow fiber membranes coated with polydimethylsiloxane (PDMS) and post-treated with PDMS-based amphiphilic copolymers shows improved performance in recovering methane from anaerobic effluents, making it a viable alternative for industrial practices.

Summary: The upflow anaerobic sludge blanket (UASB) bioreactor is a sustainable biotechnology solution for winery wastewater management. It has the potential to save energy, water, sludge waste, and chemical residue compared to aerobic wastewater treatment systems. Successful implementation of the UASB bioreactor requires preparedness to handle fluctuating wastewater discharge and meet legislative quality demands. Rapid analysis methods and post-treatment options can aid in inexpensive wastewater quality control. Optimal biogas production and COD removal in the UASB bioreactor depend on specific conditions.

Summary: Food waste generation is a major environmental concern, and lactic acid has gained attention for its role in biopolymer production. This study investigated the effects of thermal and ultrasonic pretreatment on solubilization rates and lactic acid yields. Ultrasonic pretreatment increased solubility, but reduced lactic acid concentrations and yields after fermentation. Thermal pretreatment, on the other hand, increased lactic acid concentrations and yields.

Summary: This study investigated the simultaneous removal of indium (In(III)) and selenium oxyanions (Se(IV) and Se(VI)) using anaerobic granular sludge. The results showed that the indium removal efficiency was consistently high (>95%), while the removal values for selenite (78.9-98.2%) were much higher than for selenate (15.5-70.0%) in the absence of indium. However, the presence of indium significantly improved the removal efficiency of both selenite and selenate (up to 96-98%).

Summary: The study found that aerobic granular sludge (AGS) can effectively treat antibiotic-rich wastewater containing sulfamethoxazole (SMX). The degradation of SMX involves hydrolysis of the sulfonamide bond and cleavage of N\\S or C\\S bonds, resulting in the production of small molecular substances. AGS system showed strong resistance to 0.5 mg/L of SMX, but 1 and 5 mg/L of SMX significantly inhibited microbial growth, decreased nitrification efficiency, weakened sludge settleability, and stimulated excessive growth of filamentous bacteria. The long-term presence of SMX enhanced the proliferation of antibiotic resistance genes and exerted strong selection pressure on the microbial community.

Summary: This study used aerobic granular sludge (AGS), a salt-tolerant biological wastewater treatment technology, to explore the enhancement mechanism of acid orange 7 (AO7) degradation at low salinity level (1.0%). The results showed that compared to salt-free conditions, the AO7 removal efficiency was elevated by 9.9%-19.0% at 1.0% salinity level, due to the enrichment of AO7 decolorizing bacteria (e.g. Acinetobacter) and functional enzymes (e.g. FMN-dependent azoreductase). The upregulated genes involved in key metabolic functions promoted electron and energy production, facilitating AO7 decolorization and degradation.

Summary: The membrane-aerated biofilm reactor (MABR) is a successful and promising technology for nitrification of wastewaters. The temperature dependence of a counter-diffusional biofilm's nitrification performance was investigated to improve MABR processes for colder climates. The study found that a lab-scale MABR system operated at 8 degrees C achieved a high nitrification rate, with low temperature dependence and moderate changes in microbial community composition. Proper management of mass transfer resistance can optimize the MABR process for both low and high temperature operation.

Summary: The effect of a static magnetic field (SMF) on the microbial activity of anaerobic granular sludge was investigated. The results showed that a 70 mT SMF led to improved bioH2 production, decreased lag time, increased production rate, and enhanced consumption of iron and phosphate. The SMF also induced changes in VFA production, pH and conductivity, biomass concentration, EPS composition, and settleability of the sludge. Microbial analysis revealed shifts in the relative abundance of different bacteria species in response to the SMF and heat shock pretreatment. Applying the SMF as a pre-treatment and during bioH2 production could be a promising strategy to optimize the fermentation process.

Summary: The effects of polystyrene microplastics (MPs) and nanoplastics (NPs) on microbiomes and functional genes in activated sludge systems were investigated. The results showed that low concentrations (1 mg/L) of MPs and NPs had minimal impacts on nitrogen removal performance, while high concentrations (20 and 100 mg/L) decreased total nitrogen removal efficiency. The presence of MPs and NPs induced cytotoxicity and reduced the abundance of denitrifiers and functional genes involved in nitrogen transformation processes, resulting in decreased nitrogen removal efficiency. This study provides important insights into the response of microbial communities and nitrogen conversion processes to micro(nano)plastic disturbance in activated sludge systems.
