“…This suggests that treatments applied at WWTPs are usually efficient in removing HEV. Indeed, several conventional methods are implemented in order to remove pathogens during wastewater treatment, including coagulation, filtration, chlorination, activated sludge treatment process, and anaerobic digestion (Nasir et al, 2022). Non-negligible prevalence (7.4%) was also found in surface water (river, lake, and sea).…”

Hepatitis E virus (HEV) is responsible for acute hepatitis in humans, through foodborne, zoonotic, and waterborne transmission routes. This study aimed to assess the prevalence of HEV in water matrices. Six categories were defined: untreated and treated wastewater, surface water (river, lake, and seawater), drinking water, groundwater, and other water environments (irrigation water, grey water, reservoir water, flood water, and effluent of pig slaughterhouse). We searched PubMed, Web of Science, Global Index Medicus, and Excerpta Medica Database. Study selection and data extraction were performed by at least two independent investigators. Heterogeneity (I2) was assessed using the χ2 test on the Cochran Q statistic and H parameter. Sources of heterogeneity were explored by subgroup analysis. This study is registered with PROSPERO, number CRD42021289116. We included 87 prevalence studies from 58 papers, 66.4% of which performed in Europe. The overall prevalence of HEV in water was 9.8% (95% CI 6.4–13.7). The prevalence was higher in untreated wastewater (15.1%) and lower in treated wastewater (3.8%) and in drinking water (4.7%). In surface water, prevalence was 7.4%, and in groundwater, the percentage of positive samples, from only one study available, was 8.3%. Overall, only 36.8% of the studies reported the genotype of HEV, with genotype 3 (HEV-3) prevalent (168 samples), followed by HEV-1 (148 sample), and HEV-4 (2 samples). High-income countries were the most represented with 59/87 studies (67.8%), while only 3/87 (3.5%) of the studies were performed in low-income countries. The overall prevalence obtained of this study was generally higher in industrialized countries. Risk of bias was low in 14.9% of the studies and moderate in 85.1%. The results of this review showed the occurrence of HEV in different waters environments also in industrialized countries with sanitation and safe water supplies. While HEV transmission to humans through water has been widely demonstrated in developing countries, it is an issue still pending in industrialized countries. Better knowledge on the source of pollution, occurrence, survival in water, and removal by water treatment is needed to unravel this transmission path. Graphical Abstract

“…The water permeate flow controls the filtration process's effectiveness or efficiency, and the membrane's effectiveness in rejecting the desired component determines the quality of the water permeate stream (Alfonso-Muniozguren et al, 2021). Membranes are commonly split into numerous basic categories and subcategories: microfiltration, ultrafiltration, nanofiltration, and reverse osmosis (Nasir et al, 2022a).…”

“…Ultrafiltration uses a membrane with low pressure. On average, this membrane has pores ranging from 1 to 100 nm (Nasir et al, 2022b). used hybrid systems of metal-organic frameworks (MOFs) and ultrafiltration (UF) to handle several pharmaceutically active substances, such as ibuprofen and 17-ethinyl estradiol, as well as organic debris from the environment (humic acid and tannic acid; ratios of 10:0, 5:5, and 0:10).…”

“…Operating pressures for nanofiltration membranes typically range from 3 to 30 bars. Since most nanofiltration membranes include a little charge, the separation process of these membranes uses both size sieving and electrostatic effects (Nasir et al, 2022a). investigated the filtering of specific small molecularweight pharmaceuticals from synthetic wastewater using two loose nanofiltration membranes, typically used for high molecular-weight organics.…”

Water pollution is a major environmental issue that has a wide range of impacts on ecosystems, human health, and the economy. During recent years, pharmaceutical compounds have been considered an emerging water micro-pollutant due to their potential eco-toxicity. Pharmaceuticals, personal care items, steroid hormones, and agrochemicals are synthetic and indigenous products that makeup micropollutants, also known as emerging contaminants. Due to the Corona pandemic (Covid-19), excessive use of antibiotics in addition to the painkillers used in the treatment protocol established by the World Health Organization. Thus, these compounds have become in water sources with higher concentrations. New techniques have been used to remove these environmental pollutants to achieve sustainable development goals (SDGs). This article provides a critical review of various methods presenting the potential to be applied for removing pharmaceuticals from water. Several processes: adsorption, advanced oxidation processes (photodegradation, photocatalysis, ozonation, Fenton reaction, Wet Air Oxidation, ultraviolet radiation, hydrogen peroxide oxidation), and membrane-based techniques (ultrafiltration, nanofiltration, reverse osmosis, forward osmosis, membrane distillation) are analyzed, and their performance during removal of pharmaceuticals from water is compared. Moreover, summaries presenting the efficiency of various materials applied during each process are provided. Finally, the advantages and disadvantages of each proposed method are summarised and comprehensively discussed.

“…The MBR technology can efficiently remove particles, heavy metals, and pathogens from a mixed liquor that traditional biological processes cannot usually achieve [26][27][28][29]. Then, the particle-and pathogen-free MBR effluent was introduced to a continuous flow column reactor packed with MgCO 3 pellets to recover the phosphorus.…”

Efficient Phosphorus Recovery from Municipal Wastewater Using Enhanced Biological Phosphorus Removal in an Anaerobic/Anoxic/Aerobic Membrane Bioreactor and Magnesium-Based Pellets

et al. 2022

Municipal wastewater has been identified as a potential source of natural phosphorus (P) that is projected to become depleted in a few decades based on current exploitation rates. This paper focuses on combining a bench-scale anaerobic/anoxic/aerobic membrane bioreactor (MBR) and magnesium carbonate (MgCO3)-based pellets to effectively recover P from municipal wastewater. Ethanol was introduced into the anoxic zone of the MBR system as an external carbon source to improve P release via the enhanced biological phosphorus removal (EBPR) mechanism, making it available for adsorption by the continuous-flow MgCO3 pellet column. An increase in the concentration of P in the MBR effluent led to an increase in the P adsorption capacity of the MgCO3 pellets. As a result, the anaerobic/anoxic/aerobic MBR system, combined with a MgCO3 pellet column and ethanol, achieved 91.6% P recovery from municipal wastewater, resulting in a maximum P adsorption capacity of 12.8 mg P/g MgCO3 through the continuous-flow MgCO3 pellet column. Although the introduction of ethanol into the anoxic zone was instrumental in releasing P through the EBPR, it could potentially increase membrane fouling by increasing the concentration of extracellular polymeric substances (EPSs) in the anoxic zone.
