TL;DR: More high quality data is needed on the occurrence of microplastics in drinking water, to better understand potential exposure and to inform human health risk assessments, and there is a significant need to improve quality assurance ofmicroplastic sampling and analysis in water samples.

TL;DR: In this review, the up-to-date status on the detection, occurrence and removal of microplastics in WWTPs are comprehensively reviewed and the development of potential microplastic-targeted treatment technologies is presented.

TL;DR: The results highlight leveraging the non-radical pathway dominated by singlet oxygen to conquer the inhibitory effect of anions in NGC700/PMS system, which represents a crucial step towards environmental remediation under high salinity condition.

TL;DR: This work proposes a deep insight into photosensitation-like mechanism in the photocatalysis system by using C3N4-based materials, and develops new photocatalysts for potential application on removal of emerging organic pollutants from waters and wastewaters.

TL;DR: Benefit from the electron transfer mechanism, the NBC/PDS system not only has wide pH adaptation for real application, but also shows high resistance to the inorganic anions in aquatic environment.

TL;DR: The study shows that the generation, accumulation and release of microplastic in landfills is a long-term process and provides preliminary evidence and validate that landfill isn't the final sink of plastics, but a potential source ofmicroplastics.

TL;DR: The findings suggest that microplastic is a novel microbial niche and may serve as a vector for ARGs and pathogens to new environment in river water, generating freshwater environmental risk and exerting adverse impacts on human health.

TL;DR: The large volumes of oily wastewater generated by various industries, such as oil and gas, food and beverage, and metal processing, need to be de-oiled prior to being discharged into the environment.

TL;DR: This critical analysis offers new strategies to limit the number of nano/microplastics in water and wastewater to keep water quality up to the required standards and reduce threats on the authors' ecosystems.

TL;DR: The biochar based nonradical system can provide a mild and high-efficiency strategy for disinfection in waste and drinking water by green carbocatalysis and maintain a superior oxidation efficiency in complicated water matrix and long-term stable operation.

TL;DR: Results indicated that the FeMn/bio-char/H2O2 photo-Fenton system was effective in the treatment of naphthalene in natural waters and brings a valuable insight for the potential environmental applications of modified bio-char.

TL;DR: The spatiotemporal distribution of microplastics in the Nakdong River down to 20 μm in size is investigated and it is estimated that it is necessary to reflect seasonal variation and sample both in the surface water and water column to estimate microplastic transport.

TL;DR: BDM exhibited an excellent dye removal rate, stable flux and great antifouling capacity, on the ground that adsorption saturation and foulant may be alleviated "online and in-situ" by the enzymatic degradation.

TL;DR: This article presents a timely and comprehensive review on the recent advances of various CDI cell architectures, particularly the flow-by CDI and membrane CDI with their key research activities subdivided into materials, application, operational mode, cell design, Faradaic reactions and theoretical models.

TL;DR: The findings show that MPs concentration in the influent is positively correlated with the suspended solids (SS), however, in the effluent, it is associated with the WWTPs operating load, as reflected by obviously higher MP abundance in overloaded ones.

TL;DR: The field is reviewed from the rather fundamental research on biofilm morphology and microbial community analysis to the impact of feedwater composition, process parameters and organic removal performance and the application potential is highlighted in comparison to conventional ultrafiltration.

TL;DR: It is suggested that anoxic-carrier biofilms might be a candidate to enhance nitrogen removal through partial anammox in municipal WWTPs.

TL;DR: Results of the present study suggest that current treatment technologies employed at the chosen STP are efficient to remove the majority of microplastics, however consideration of STPs as a point source of micro Plastics is important due to the large volumes of effluents being released into the aquatic environment on a consistent basis.

TL;DR: The results suggest that CNTs/PS system combined with regeneration based on UV irradiation can be used as an effective alternative process for continuous degradation of recalcitrant aqueous contaminants through the non-radical mechanism.

TL;DR: One way forward would be a prevalence study to identify the priority candidates of tentatively abundant, persistent, and toxic cyanopeptides to make comprehensive risk assessments more manageable.

TL;DR: Further research is needed to exploit microalgal species for EC bioremediation properties, such as increased bioadsorption, enhanced biodegrading enzymes and optimised growth conditions, which can be a cost-effective viable option for the reduction of contaminant pollution in waterways.

TL;DR: The results imply that increased adsorption potentials of the sludge-based MPs to Cd are attributed to changes in the MP physicochemical properties during wastewater treatment process, and should be further concerned.

TL;DR: A multidisciplinary roadmap for addressing this EPS identity crisis is proposed, which involves improved EPS extraction and characterization methodologies, cross-referencing between model biofilms and full-scale biofilm systems, and functional description of isolated EPS with in situ techniques coupled with genomics, proteomics and glycomics.

TL;DR: The main parameters that affect the economics of phosphate adsorption are discussed, a scenario and sensitivity analysis shows the importance of adsorbent regeneration and reuse and the research gaps are highlighted.

TL;DR: The results of SEM, AFM, hydrophilicity and ATR-FTIR proved that the existence of the maximum membrane fouling at the critical AGS size, which possessed the highest cake layer, pore blocking and irreversible fouling, which generally existed in various operational conditions.

TL;DR: The selective adsorbent of Cr(VI) was demonstrated in binary adsorption systems with coexisting ions and could be observed by the XPS results and SEM results showed good dispersion of the PPy on the clay sheets.

TL;DR: It was clearly demonstrated in this study that higher ozone doses were required in order to confer permanent damage and/or death and prevent potential post-treatment re-growth of both total bacteria and ARB, and to reduce the abundance of ARGs below the LOQ.

TL;DR: An overview of data-driven methods of achieving fault detection, variable prediction, and advanced control of WWTP is provided and practical guidance is given for matching a desired goal with a particular methodology along with considerations regarding the assumed data structure.

TL;DR: The profiles and relationships between microbial community and ARGs in AS process treating wastewater with high antibiotic concentrations are deciphered and could provide helpful guidance for controlling the development and dissemination of ARB and ARG.

TL;DR: It was found that, although being low content, SMPs rather than sludge particulates preferentially adhered to membrane surface to accumulate a gel layer, and specific filtration resistance of S MPs was approximately 700 times larger than that of the sludge particle at operational day 3.
