“…Correspondingly, as indicated in Table 3 , electrospinning and phase inversion are the most frequently applied methods to manufacture PVDF, PSF, CA membranes predominantly exploited for the rejection of EDCs from potable and synthetic water. Technically, the phase inversion method comprises non-solvent induced phase separation (NIPS) (a leading method), thermal phase separation, and regulated evaporation, and lastly, vapor induced phase inversion (VIPS) [ 112 ]. Most of the composite membranes utilized in the rejection of EDCs contaminants possess pore size ranged from 0.0003–357 µm, which is comparatively lower than the size of some EDCs contaminants, therefore might be efficient to retain some of the EDCs contaminants during the membrane filtration processes as indicated in Table 3 .…”

Water is a critical resource necessary for life to be sustained, and its availability should be secured, appropriated, and easily obtainable. The continual detection of endocrine-disrupting chemicals (EDCs) (ng/L or µg/L) in water and wastewater has attracted critical concerns among the regulatory authorities and general public, due to its associated public health, ecological risks, and a threat to global water quality. Presently, there is a lack of stringent discharge standards regulating the emerging multiclass contaminants to obviate its possible undesirable impacts. The conventional treatment processes have reportedly ineffectual in eliminating the persistent EDCs pollutants, necessitating the researchers to develop alternative treatment methods. Occurrences of the EDCs and the attributed effects on humans and the environment are adequately reviewed. It indicated that comprehensive information on the recent advances in the rejection of EDCs via a novel membrane and membrane bioreactor (MBR) treatment techniques are still lacking. This paper critically studies and reports on recent advances in the membrane and MBR treatment methods for removing EDCs, fouling challenges, and its mitigation strategies. The removal mechanisms and the operating factors influencing the EDCs remediation were also examined. Membranes and MBR approaches have proven successful and viable to eliminate various EDCs contaminants.

Some of the groundwater aquifers in the Puglia Region, Italy, suffer from high salinity and potential micropollutant contamination due to seawater infiltration and chemical discharge. The objective of this study is twofold: to evaluate the performance of the recently reported alumina-doped silica nanofiltration membranes for water potabilization, and to provide a possible solution to improve the groundwater quality in the Puglia Region while maintaining a low energy-footprint. Two lab-made alumina-doped silica membranes with different pore structures, namely S/O = 0.5 and S/O = 2, were tested with real groundwater samples and their performances were compared with those of a commercial polymeric membrane (Dow NF90). Moreover, groundwater samples were sparked with acetamiprid, imidacloprid, and thiacloprid to test the membrane performance in the presence of potential contamination by pesticides. At a trans-membrane pressure of 5 bar, NF90 could reduce the groundwater conductivity from 4.6 to around 1.3 mS·cm−1 and reject 56–85% of the model pesticides, with a permeate flux of 14.2 L·m−2·h−1. The two inorganic membranes S/O = 2 and S/O = 0.5 reduced the permeate conductivity to 3.8 and 2.4 mS·cm−1, respectively. The specific energy consumption for all three membranes was below 0.2 kWh·m−3 which indicates that the potabilization of this groundwater by nanofiltration is commercially feasible.

“…The mechanisms of nanofiltration membrane to remove organic micropollutants usually consisted of electrostatic interaction, hydrophobic interaction, and steric hindrance [21]. Licona et al [22] studied the effect of surface properties of nanofiltration membrane on the rejection performance of many kinds of phAc under different pH value conditions. They found that the rejection performance of nanofiltration membrane was affected by many factors, and this effect was the result of the interaction of many kinds of forces.…”

Phthalate esters (phthalic acid esters or PAEs) are widely utilized during production as an inactive plasticizer, which results in serious water pollution. Ideal removal of micropollutants is difficult to achieve with traditional water treatment, but technology using nanofiltration membrane removes water micropollutants effectively owing to its unique membrane structure. To further study the rejection performance of nanofiltration membrane for PAEs, carbon nanotube-modified nanofiltration membrane was proposed to treat PAEs in water. The adsorption and rejection properties of PAEs on the surface of nanofiltration membrane were revealed by multi-factor experiments. Adsorption kinetics was also analyzed, and the adsorption isotherm of PAEs on the membrane surface was simulated. In addition, the effects of running time, molecular weight, n-octanol/water partition coefficient, and average polarizability on the performance of PAE rejection of nanofiltration membrane were discussed. Results show that the Freundlich adsorption equation simulates the adsorption of PAEs on the surface of the nanofiltration membrane, and the correlation coefficient is more than 0.998. The adsorption capacity of the nanofiltration membrane for three typical PAEs substances, namely, diethyl phthalate (DEP), dibutyl phthalate (DBP), and dioctyl phthalate (DOP), decreases in turn. At the same time, the early rejection of PAEs by nanofiltration membrane is primarily due to the adsorption of membrane surface, and the equilibrium stage depends mainly on the sieving effect of the membrane pores. This study provides a theoretical basis for the application of nanofiltration membrane in the removal of PAEs.
