TL;DR: Recommendations regarding the use of the EEO concept, including the upscaling of laboratory results, were derived from an extensive analysis of studies reported in the peer-reviewed literature enabling a critical comparison of various established and emerging AOPs based on electrical energy per order (EEO) values.

TL;DR: Many antibiotics were detected in the influents and effluents of WWTPs at concentrations close to or exceeding the predicted no-effect concentrations (PNECs) for resistance selection.

TL;DR: It is shown that micro-Raman spectroscopy is particularly useful in detecting microplastics in drinking water where particle sizes are in the low micrometer range, and indicates that the packaging itself may release microparticles.

TL;DR: This is the first study reporting about microplastics, pigment and additive particles found in bottled mineral water samples with a smallest analysed particle size of 1 μm, and thus not covered by previous studies.

TL;DR: An overview of the types and mechanisms of Faradaic reactions in CDI systems including anodic oxidation of carbon electrodes, cathodic reduction of oxygen and FarADAic ion storage are presented and their apparent negative and positive effects on water desalination are identified.

TL;DR: A broad review is carried out on wetting incidence in membrane distillation processes and describes the wetting mechanisms, wetting causes, and wetting detection methods, as well as hydrophobicity measurements of MD membranes.

TL;DR: By comprehensively analyzing the influential factors and complete degradation pathway of TC electrochemical oxidation on the Ti/Ti4O7 anode, the research provides deeper insights into the risk assessment of intermediates and their toxicity, assigning new perspectives for practical electrochemical oxide to effectively eliminate the amount and toxicity of TC and other antibiotics in wastewater.

TL;DR: This study proves the potential of novel nonmetal porous photocatalyst to simultaneously treat wastewater while converting solar energy into clean hydrogen energy.

TL;DR: This review comprises the work conducted by various researchers in the field of the removal and recovery of spilled oils using various biomasses and polymers, either in the form of sorbents or separators.

TL;DR: A showcase of interesting and easily available solutions that contribute to faster and better identification of microplastics using Raman spectroscopy and non-conventional Raman techniques (non-linear Raman, hyperspectral imaging, standoff Raman) which permit more advanced applications such as real-time Raman detection and imaging of micro Plastics.

TL;DR: It is concluded that reliable knowledge on transport mechanism to surface waters, concentrations in surface waters and sediments, effects of aging, environmental half-lives of TWP as well as effects on aquatic organisms are missing are missing and need to be addressed to allow for the assessment of risk ofTWP in an aquatic environment.

TL;DR: Aiming at the complicated composition of sludge and its treatment difficulty, the prospects and technical developments of coagulation/flocculation in sludge dewatering are discussed.

TL;DR: There is a continued need to increase the field-data bases about plastics (all size fractions) in freshwater environments, especially in countries with rapid economic development and poor waste management, and to estimate river plastic emissions to the world's oceans.

TL;DR: To protect the ecosystem and drinking water resources in Switzerland and in the countries of the downstream catchments, a new Swiss water protection act entered into force in 2016 aiming to reduce the discharge of micropollutants from wastewater treatment plants (WWTPs), selected WWTPs must be upgraded by an advanced treatment with suitable and economic options.

TL;DR: It is concluded that the adsorption capacities are well-related to surface hydrophobicity/hydrophilicity and structural features, e.g. micropore volume and pore size of high-silica zeolites, as well as the properties of OMPs.

TL;DR: Despite the overall high degradation efficiency of the UV LED-based AOPs, practical implementation is still limited and at lab scale, and more research on real water matrices at more environmentally relevant concentrations, as well as an estimation of energy requirements providing fluence-based kinetic data are required.

TL;DR: A comprehensive overview on the field applications of various soil remediation technologies performed over the last decade or so is provided, and key knowledge gaps and practical challenges are identified.

TL;DR: A critical review of the development and fabrication of carbonaceous-TiO2 and its application to PPCP removal including its influence on water chemistry, and the relevant operational parameters is presented.

TL;DR: This work develops a highly practical adsorption process based on hydrogel adsorbents for the removal of heavy metals in actual wastewater.

TL;DR: This review describes recent progress made in the development of concentration and detection methods of human enteric viruses in water, and discusses their applications for providing a better understanding of the prevalence of the viruses in various types of water worldwide.

TL;DR: An overall picture about the current status of MPs in WWTPs across China is drawn and provides useful information for better control of the risks associated with MPs.

TL;DR: The chlorine disinfection could increase the abundances of both iARGs and eARGs, thereby posing risk of the dissemination of antibiotic resistance in environments.

TL;DR: Overall, suitability of DNA-based identification is particularly high for fish, as eDNA is a well-suited sampling approach which can replace expensive and potentially harmful methods such as gill-netting, trawling or electrofishing.

TL;DR: The UV/chlorine approach was superior to the UV/H2O2 approach for the removal of all PPCPs in simulated drinking water and wastewater at the same molar oxidant dosage and saved 3.5-93.5% and 19.1%-98.1% electrical energy per order (EE/O) for PPCP degradation in simulated Drinking water andewater, respectively.

TL;DR: This study constructed a 1000 L modularized MFC system, the largest volume so far, to treat practical municipal wastewater, which stably met the level A of the first class in discharge standard of pollutants for MWTP of China.

TL;DR: It is suggested that Fe-P coupling mechanisms are responsible for the release of P from sediments during HABs, as changes in soluble reactive phosphorus (SRP) and soluble Fe(II) concentrations in the top 20 mm sediment layer on a 3-h time interval suggest.
