“…Aerobic MBR demonstrates superior performance in antibiotic removal compared to the convetional activated sludge process (ASP) as shown in Table 4.The removal rate of different antibiotics by ASP (ciprofloxacin:71-89%; erythromycin:43-66% amoxillin:100%; sulfamethoxazole 52-70%; trimethoprim 31-33%; tetracycline:67-96%) and by aerobic MBR (ciprofloxacin:29-93%; erythromycin:12-90%; sulfamethoxazole:7-100%; trimethoprim: − 2 to 96%; amoxillin: 86-92%; and tetracycline: 56-97%).The high removal observed in aerobic MBR might due to absolute particle retention facilitated by the membranes and heightened biodegradation achieved through extended SRT and increased biomass concentrations [132].…”

China still dominates all other nations as the world's most significant producer and consumer of antibiotics. Antibiotic misuse and overuse have been qualitatively and quantitatively documented in China recently. Antibiotic misuse has alarmed the Chinese population because some antibiotics persist in the environment and adversely affect human health and other non-target organisms. Antibiotic priority setting has been considered the best monitoring tool that is also affordable and time-efficient. Therefore, this article aims to assess the status methods of antibiotic prioritization within ten years ago years (2012–2022) in China and its prevalence and removal by conventional wastewater treatment facilities. Twenty-six priority antibiotics in China may need more attention, according to a recent prioritization assessment. According to other nations, the outcomes of prioritization vary from one nation to another. However, the same antibiotics are frequently reported despite applying various prioritization techniques (method). Their prevalence and frequent detection in China’s environmental media indicate that conventional treatment plants cannot remove them from effluents altogether. Their removal patterns vary from wastewater treatment plant (WWTP) to another and are affected by different factors, including pH, physical–chemical properties of the antibiotic compound, temperature, sludge retention time (SRT), hydraulic retention time (HRT), and the amount of microorganism present.

“…Several studies on MPBR have been conducted by various research groups with different microalgae species and MPBR configurations [15][16][17][18]. These studies have demonstrated the advantages of MPBR systems for nutrient removal and microalgae biomass production compared to the conventional microalgae system [19].…”

Developing an effective phycoremediation system, especially by utilizing microalgae, could provide a valuable approach in wastewater treatment for simultaneous nutrient removal and biomass generation, which would help control environmental pollution. This research aims to study the impact of low-voltage direct current (DC) application on Chlorella vulgaris properties and the removal efficiency of nutrients (N and P) in a novel electrokinetic-assisted membrane photobioreactor (EK-MPBR) in treating synthetic municipal wastewater. Two membrane photobioreactors ran in parallel for 49 days with and without an applied electric field (current density: 0.261 A/m2). Mixed liquid suspended soils (MLSS) concentration, chemical oxygen demand (COD), floc morphology, total phosphorus (TP), and total nitrogen (TN) removals were measured during the experiments. The results showed that EK-MPBR achieved biomass production comparable to the control MPBR. In EK-MPBR, an over 97% reduction in phosphate concentration was achieved compared to 41% removal in the control MPBR. The control MPBR outperformed the nitrogen removal of EK-MPBR (68% compared to 43% removal). Induced DC electric field led to lower pH, lower zeta potential, and smaller particle sizes in the EK-MPBR as compared with MPBR. The results of this novel study investigating the incorporation of Chlorella vulgaris in an electrokinetic-assisted membrane photobioreactor indicate that this is a promising technology for wastewater treatment.

Slug bubbling in single deck flat sheet membrane bioreactor (FSMBR) is effective in controlling membrane fouling. Here the primary focus is on the employment of the slug bubbling method, with its more economical air consumption, to a double‐deck large‐scale FSMBR with 100 membrane plates on each deck. The analysis of a new design concept shows that sufficient hydrodynamic effect could be induced by a novel economical three‐stage slug aeration process of formation‐breakup‐reformation. Computational fluid dynamics simulation was applied to examine both the development of the slug bubble and especially its reformation. It was found that the combination of a gap between two decks of 400 mm with an air velocity of 16 m/s was an optimal condition to achieve good hydrodynamic conditions in both decks. The corresponding SADm is 0.098 Nm3m−2 hr−1, which is a reduction of 66% compared to the most advanced single deck FSMBR.
