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.

“…Membrane technology is the most extensively applied physicochemical separation technology for the removal of salt and microbes from water [ 100 , 101 , 102 ]. Membrane processes have been productively utilized in difficulties relating to unavailability of fresh and clean water and could remove EDCs and natural organic matter (NOM) from both wastewater reuse and drinking water [ 103 , 104 ].…”

Over the years, the persistent occurrence of superfluous endocrine-disrupting compounds (EDCs) (sub µg L−1) in water has led to serious health disorders in human and aquatic lives, as well as undermined the water quality. At present, there are no generally accepted regulatory discharge limits for the EDCs to avert their possible negative impacts. Moreover, the conventional treatment processes have reportedly failed to remove the persistent EDC pollutants, and this has led researchers to develop alternative treatment methods. Comprehensive information on the recent advances in the existing novel treatment processes and their peculiar limitations is still lacking. In this regard, the various treatment methods for the removal of EDCs are critically studied and reported in this paper. Initially, the occurrences of the EDCs and their attributed effects on humans, aquatic life, and wildlife are systematically reviewed, as well as the applied treatments. The most noticeable advances in the treatment methods include adsorption, catalytic degradation, ozonation, membrane separation, and advanced oxidation processes (AOP), as well as hybrid processes. The recent advances in the treatment technologies available for the elimination of EDCs from various water resources alongside with their associated drawbacks are discussed critically. Besides, the application of hybrid adsorption–membrane treatment using several novel nano-precursors is carefully reviewed. The operating factors influencing the EDCs’ remediations via adsorption is also briefly examined. Interestingly, research findings have indicated that some of the contemporary techniques could achieve more than 99% EDCs removal.

“…Numerous studies have demonstrated that nanofiltration membrane separation technology can effectively remove PAEs from water [16][17]. Zhu et al [18] successfully prepared a new composite membrane with filtration and adsorption properties, with polyvinylidene fluoride (PVDF) as base membrane. The removal rate of BPA is more than 80% within the contact time of 1.3s when the pressure is 0.5 MPa, and the reuse rate of the membrane is high.…”

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.
