Summary: The Sponge membrane bioreactor (Sponge-MBR) demonstrated effective performance in treating tannery wastewater, despite the inhibition of suspended biomass growth by the wastewater. The attached biomass of sponge carriers significantly contributed to the removal of organic matters and a portion of total nitrogen. Additionally, the dynamic movement of sponge carriers helped reduce fouling rate in the system.

Summary: Membrane bioreactor (MBR) technology is considered a promising method for advanced wastewater treatment due to its high-quality effluent. However, fouling caused by intensive activated sludge used in submerged MBR systems is a major issue. To overcome this problem, researchers have explored the use of vibratory processes in MBRs. This review aims to gather current efforts in fouling control by vibratory motion, specifically in submerged activated sludge membrane bioreactors, and presents a comparative analysis of different vibration types and their experimental results.

Summary: Microplastics are a major threat to the environment and aquatic life, and one of the main sources of microplastics in water and land environments is wastewater treatment plants. This study aimed to investigate the presence and removal of microplastics in wastewater and sludge from different types of treatment plants. The results showed high removal efficiency in the treatment process, with a decrease in microplastic concentration from influent to effluent. The most common forms of microplastics detected were fragments and fibers, and several types of polymers were identified.

Summary: This study investigates the performance of a membrane bioreactor (MBR) in treating saline-contaminated municipal wastewater. The results show that the MBR system exhibits high removal efficiencies for chemical oxygen demand (COD) and ammonium-N within a certain range of salinity concentrations. The analysis of bacterial composition suggests that specific bacteria play important roles in the biodegradation process. Therefore, the MBR system can be an effective solution for treating municipal wastewater occasionally contaminated with seawater.

Summary: Municipal wastewater treatment is a sustainable method for protecting and reusing fresh water resources. This study found that adding ferric chloride can enhance the removal of total phosphorous, but it does not improve membrane filterability or sludge flocculation. To improve phosphorus removal in MBR systems, it is recommended to add coagulants to the final permeate.

Summary: This study demonstrated that a microbial community dominated by fungi could be successfully maintained in a pilot-scale packed-bed reactor fed with tannery wastewater under non-sterile conditions. The reactor, inoculated with a pure culture of Aspergillus tubingensis and Quebracho tannin as sole carbon source during start-up, achieved significant removal of COD and DOC from the tannery wastewater. The evolution of the microbial consortium and its adaptation to the support media size were examined throughout the experiment.

Summary: The potential inhibitory effect of biologically pre-treated vegetable tannery wastewater (TW) on anammox granular biomass was studied. The high salinity and tannins concentration in vegetable TW were found to be the main inhibitory factors. Salinity at a conductivity of 10 mS/cm had the greatest impact on the specific anammox activity. The results suggest that there are no technical limitations for using the anammox process for vegetable TW, but preliminary biomass acclimation and regular activity monitoring are recommended for long-term applications.

Summary: This study highlights the importance of controlling mineral precipitation on granular sludge systems treating wastewaters prone to inert precipitation to ensure long-term stability. Severe mineral precipitation on the granules' surface can lead to deteriorated reactor performance and biomass activity, with potential mechanisms including substrate diffusion limitation, insufficient mixing, and biofilm erosion. Gravimetric selection proved effective in restoring process performance affected by mineral precipitation.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
