Microplastics of millimeter dimensions have been widely investigated in environmental compartments and today, studies are mainly focused on particles of smaller dimensions (< 500 µm). However, as there are no relevant standards or policies for the preparation and analysis of complex water samples containing such particles, the results may be questionable. Therefore, a methodological approach for 10 µm to 500 µm microplastic analysis was developed using μ-FTIR spectroscopy coupled with the siMPle analytical software. This was undertaken on different water samples (sea, fresh, and wastewater) taking into consideration rinsing water, digestion protocols, collection of microplastics, and sample characteristics. Ultrapure water was the optimal rinsing water and ethanol was also proposed with a mandatory previous filtration. Although water quality could give some guidelines for the selection of digestion protocols, it is not the only decisive factor. The methodology approach by μ-FTIR spectroscopy was finally assessed to be effective and reliable. This improved quantitative and qualitative analytical methodology for microplastic detection can then be used to assess the removal efficiency of conventional and membrane treatment processes in different water treatment plants.

The distribution and fate of microplastics in different water sources and their treatment plants (seawater, three municipal wastewaters, a pharmaceutical factory wastewater, and three drinking waters) in France were studied. Currently, research in this field is still under exploration since almost no relevant standards or policies have been introduced for the detection, the removal, or the discharge of microplastics. This study used an improved quantitative and qualitative analytical methodology for microplastic detection by μ-FTIR carried out with siMPle analytical software. By investigation, wastewater was determined to contain the most abundant microplastics in quantity (4,203-42,000 MP·L-1), then followed by surface water/groundwater (153-19,836 MP·L-1) and seawater (around 420 MP·L-1). Polyethylene was the dominant material in almost all water types followed by polypropylene, polystyrene, and polyethylene terephthalate. Almost all treatment technologies could remove microplastics whatever the feed water types and concentration of microplastics, though some treatment processes or transport pipes could cause additional contamination from microplastics. The four WWTPs, three DWTPs, and SWTP in France provided, respectively, 87.8-99.8%, 82.3-99.9%, 69.0-96.0% removal/retention of MPs in quantity, and provided 97.3-100%, 91.9-99.9%, 92.2-98.1% removal/retention of MPs in surface area. Moreover, ultrafiltration was confirmed to be an effective technology for microplastic retention and control of dimensions of microplastics in smaller ranges both in field-scale and lab-scale experiments. The 200 kDa ultrafiltration membrane could retain 70-100% and 80-100% of microplastics in quantity and in surface area, respectively.

Shellfish as a foodstuff must meet sanitary quality objectives for the protection of consumers and this quality is closely linked to the water. The oyster industry considered this challenge related to contaminations and currently, the major risk of disease is due to the presence of norovirus (NoV) since all oyster-consuming countries report outbreaks of gastroenteritis linked to the presence of this microorganism. Ultrafiltration has already demonstrated to be efficient for viral protection of oyster farms in previous studies. In this work, retention by ultrafiltration of Tulane virus, a NoV surrogate, was evaluated. The effect of virus concentration in the feed on the ultrafiltration efficiency has been assessed. Low retentions of about 1 log were observed at the lowest viral concentrations. At higher concentrations, an increase of retention up to 5 log was obtained. These results highlight the potential overestimation of UF efficiency during laboratory experiments realized at high concentrations, compared to low concentrations found in environmental resources. In agreement with other studies, higher retentions at high concentrations could be explained by formation of viral aggregates, which could facilitate the steric exclusion but also modify the electrostatic and hydrophobic interactions between isolated viruses/aggregates and membrane. Virus retentions with a fresh mineral water (Evian water) and seawater were compared. Seawater achieved higher retention rates for Tulane virus due to the membrane fouling.

To improve membrane fouling management, the NaClO-assisted backwash has been developed to improve permeability maintenance and reduce the need for intensive chemical cleanings. This study is aimed to focus on the efficiency of NaClO-assisted backwash in real UF pilot scale and with periodic classic backwash (CB) and air backwash (AB). The impacts on hydraulic filtration performance, physicochemical properties of membrane material under different addition frequencies of NaClO, and the performance of chlorinated CB and AB will be discussed. In result, 10 mg Cl2 L−1 NaClO addition in backwash water is confirmed to greatly improve the overall filtration performance and backwash cleaning efficiency. One condition stands out from the other due to better control of irreversible fouling, less NaClO consumption in 10 years prediction, sustainable and adaptable filtration performance, and less potential damage on the physicochemical properties of the membrane. Additionally, it can be inferred from this experiment that frequent contact with NaClO induced some degradation on the PES-made UF membrane surface properties. To retain the best state of UF membrane on anti-fouling and qualified production, the optimized condition with more frequent NaClO contact was not suggested for long-term filtration.

Water reuse is an enduring topic that benefits the society and future generations of mankind. Ultrafiltration (UF) is one of the most cost-effective treatment technologies for improving water quality. In this study, a semiindustrial UF pilot plant with periodical classic backwash (CB) and air backwash (AB) was operated automatically to evaluate its feasibility and sustainability for municipal wastewater reuse and find out the optimized filtration condition. This study carried out 15 filtration conditions to investigate the impacts of flux (J in L center dot h-1 center dot m- 2), filtration cycle time (t in min), and air backwash frequency (BW) on membrane hydraulic filtration performance and membrane fouling management. Through comparative analysis of all conditions in water quality, permeability variation, irreversible fouling management, and water recovery rates, the sustainable conditions J80t40BW1/3 (flux of 80 L center dot h- 1 center dot m- 2, filtration cycle time of 40 min, 1 AB followed with 3 CBs), J60t60BW1/4 (flux of 60 L center dot h- 1 center dot m- 2, filtration cycle time of 60 min, 1 AB followed with 4 CBs), and J60t60BW1/ 3 (flux of 60 L center dot h- 1 center dot m- 2, filtration cycle time of 60 min, 1 AB followed with 3 CBs), stood out from the others with higher overall performances. Additionally, air backwash showed excellent reversibility on membrane fouling control, which was around 1.25-2 times that of CB in average. After all, long term operation on condition J60t60BW1/3 in winter and in summer confirmed that the UF system could provide sustainable and adaptable filtration performance regardless of the temperature and feed water quality. The UF permeate quality is good enough to be reused in non-potable applications as it met reuse guidelines of the World Health Organization, reuse standards of France and the most recent EU regulation for agricultural irrigation. This work confirms the great interest of UF as tertiary treatment for water reuse and gives operational indications for future industrialscale production of reclaimed water.

Gamification is a widespread phenomenon that relies on using game mechanics in other areas, such as the learning situation. One of the most exciting types of games in the late 2010s is escape games, where the principle is for the players to manage to escape from a room in which they are locked by finding hidden items and following a sequence of puzzles. The goal of using this type of game is to motivate/involve learners, to make them work and develop adaptability and responsiveness skills. Unfortunately, these escape games are only practiced in small groups, and the design is expensive and time-consuming. That is why cost-effective alternatives are proposed in this paper. They are either dematerialized, entirely based on a digital medium (smartphone/tablets/computer), or directly created by students, also with a digital medium, allowing integration into large classes, or at open house events.

Dynamic simulation of ultrafiltration process is applied to the treatment of chemical mechanical polishing wastewater from microelectronic industry. The ultrafiltration of nanoparticles (NPs) contained in chemical mechanical polishing wastewater is modelled by using different mathematical equations, which are derived from the literature and optimized to the effluent and filtration modes (dead-end or crossflow). A series of ultrafiltration experiments at laboratory scale are carried out by using chemical mechanical polishing wastewater to optimize and validate the models. Complete dead-end and crossflow ultrafiltration models are developed to simulate the treatment performances of chemical mechanical polishing wastewater under dynamic full-scale and different operating conditions, thus including filtration and washing steps. Simulations show that the dead-end mode is not suitable for chemical mechanical polishing wastewater concentration higher than 100 mgNPs L-1 due to the too fast fouling time and to the high frequency of washing step. The high concentration of chemical mechanical polishing P wastewater (2600 mgNPs L-1) forces industries to use crossflow ultrafiltration to have a profitable process by controlling parameters such as the filtration/backwashing number of cycles, the needed filtering surface and the filtration flux.

This work aims to analyse the performances of a new hybrid process: membrane filtration to concentrate biorefractory wastewater before being treated by a hydrothermal process such as wet air oxidation. The aim is to obtain a complete discharge of the effluent in the environment. The three different synthetic wastewaters under study were pharmaceutical wastewater, grey wastewater and bilge wastewater. The results of the membrane filtration showed high retention rates as it could reach between 75% and 100% of total organic carbon rentention, more than 99% of turbidity removal and more than 70% of hydrocarbon retention. Moreover, it was possible to achieve high concentration factors comprised between 17 and 40 times. Membrane fouling was chemically reversible regardless of the type of pollution. Then, the treatment of the membrane retentates by wet air oxidation process (300 °C, 15 MPa) could eliminate more than 83% of organic pollution for all the tested effluents. In summary, the hybrid intensified process could finally decrease the volume and the waste load of wastewater before possibly discharging it into the environment.

Wastewater reuse as a sustainable, reliable and energy recovery concept is a promising approach to alleviate worldwide water scarcity. However, the water reuse market needs to be developed with long-term efforts because only less than 4% of the total wastewater worldwide has been treated for water reuse at present. In addition, the reclaimed water should fulfill the criteria of health safety, appearance, environmental acceptance and economic feasibility based on their local water reuse guidelines. Moreover, municipal wastewater as an alternative water resource for non-potable or potable reuse, has been widely treated by various membrane-based treatment processes for reuse applications. By collecting lab-scale and pilot-scale reuse cases as much as possible, this review aims to provide a comprehensive summary of the membrane-based treatment processes, mainly focused on the hydraulic filtration performance, contaminants removal capacity, reuse purpose, fouling resistance potential, resource recovery and energy consumption. The advances and limitations of different membrane-based processes alone or coupled with other possible processes such as disinfection processes and advanced oxidation processes, are also highlighted. Challenges still facing membrane-based technologies for water reuse applications, including institutional barriers, financial allocation and public perception, are stated as areas in need of further research and development.

Bio‐refractory wastewater treatment is compulsory for a safe discharge into the environment. This paper aims to study the use of membrane processes to concentrate wastewater to be then treated by a hydrothermal process such as wet air oxidation for advanced and intensified wastewater treatment. The work focused on three different synthetic wastewaters of public or industrial interest: pharmaceutical wastewater, grey wastewater, and bilge wastewater. Membrane processes operated at the pilot scale enabled retentions as high as 100% of total organic carbon, more than 99% of turbidity, and 70% of hydrocarbon, respectively. High concentration factors were obtained. Membrane foulings were chemically reversible whatever the type of wastewater or the membrane process. Thanks to membrane filtrations, the volumes to be treated by wet air oxidation were drastically reduced, leading to high energy savings. Membrane retentates were then treated by wet air oxidation (300°C, 15 MPa) and resulted in more than an 83% mineralization rate, regardless of the effluent. The hybrid intensified process presented in this work strongly increased the possibility of discharging into the environment by mixing the process outputs or greatly reducing the discharge volume and ultimately the waste load.
