“…In order to improve the effectiveness of polyethersulfone (PES) membranes for mi-cropollutant removal, Kaminska et al [39] inserted "small amounts of single walled carbon nanotubes" in this membrane, which increased the adsorption of bisphenol A and nonylphenol. But, the authors warn about that increase of the pressure can diminish the removal, probably because the porosity of the membrane and the convection through it.…”

Micropollutants are defined as contaminants found in trace concentrations in water bodies that are persistent and bioactive, meaning they are not completely biodegradable and cannot be removed by conventional water treatment methods. Because of these aspects, their detection and removal pose a challenge to the scientific community. Among them are endocrine disruptors, drugs, agricultural chemicals, personal grooming products, industrial additives and others. These micropollutants are the cause for global concern, because their presence in water supply systems is suspected of causing health problems in humans and animals. To develop efficient techniques to remove them, it is fundamental to understand their physico-chemical properties and the available treatment types and conditions. Membrane separation processes (MSPs) and advanced oxidation processes (AOPs) are the focus of this literature review, as potential treatment methods to remove micropollutants. The former process stands out for high rejection rates (above 90%) of various micropollutants, but it generates a concentrated secondary waste stream. In turn, the latter process can remove micropollutants without generating secondary wastes, and can also be applied and combined with other treatment methods.

“…The higher j values of the PES membrane at a higher pH shows that the surfaces of the PES membranes were more negative due to the nature of the sulphonic group (O¼S¼O), which dissociates markedly at high pH values [45]. The observed positive charge on the PES membrane surface could be attributed to positive ion adsorption in the course of measuring the streaming potential [37]. In contrast, j of the N-CNT/PES blend membranes was observed to be more positive at lower pH and more negative at higher pH with IEPs at pH 7.0, 6.8, 6.0, and 5.8 for the 0.01, 0.03, 0.05, and 0.1 wt% N-CNT/PES blend membranes, respectively.…”

“…A study by Kaminska et al revealed that the incorporation of small quantities of single‐walled carbon nanotubes (SWCNT) in PES membranes improved adsorption and removal of endocrine disrupting micropollutants (technical 4‐nonylphenol, NP, and bisphenol A, BPA) from synthetic wastewater. Fabrication of nitrogen‐doped carbon nanotubes/polyethersulfone (N‐CNT/PES) blend membranes provides a unique opportunity to eliminate these recalcitrant compounds, that is, EMPs, from drinking water systems .…”

Emerging micropollutants (EMPs) are ubiquitous in water systems and have become a worldwide issue of emerging environmental concern. This paper reports on the fabrication of nitrogen‐doped carbon nanotubes/polyethersulfone (N‐CNT/PES) blend membranes that have the potential to remove EMPs such as carbamazepine, galaxolide, caffeine, tonalide, technical 4‐nonylphenol, and bisphenol A from water. The target compounds were extracted and enriched by solid‐phase extraction and analyzed using comprehensive two‐dimensional gas chromatography coupled‐to‐time‐of‐flight mass spectrometry. The N‐CNT/PES blend membranes were synthesized using the modified phase‐inversion method and characterized for a variety of physicochemical properties. The permeation properties of the membranes were determined by computing rejection and pure water flux. The 0.01 wt% N‐CNT/PES blend membrane were observed to have highest surface area (94.3 ± 0.60 m2/g) and porosity (0.37 ± 0.03 cm3/g). The water flux of the membranes was enhanced by the addition of N‐CNTs to the pristine PES membranes. The contact angles for the N‐CNT/PES blend membranes gradually declined from 78.39° for the PES membrane to 62.7°, 58.9°, and 58.75° for the 0.01, 0.03, 0.05 wt% N‐CNT/PES blend membranes, respectively. The N‐CNT/PES blend membranes were highly proficient in removing the selected EMPs with the highest and lowest removal efficiencies being 99.20–99.92% (for galaxolide) and 84.61–87.21% (for caffeine), respectively. The results show the superior capability of the N‐CNT/PES blend membranes in removing EMPs from water.

“…Several techniques, including advanced oxidation processes (AOPs) [9][10][11], membrane filtration [12,13], coagulation [14], and adsorption [15,16] have been used to remove micropollutants from different aqueous media. AOPs and membrane filtration are very effective for the elimination of…”

Organic micropollutants enter effluent streams and then flow into receiving waters. The volume adversely affects aquatic biota substantially. Therefore, many efforts have been made to develop methods for their elimination. The aim of this study was the removal of organic micropollutants with different properties from WWTP (wastewater treatment plant) effluent in fixed bed columns packed with several combinations of sand, granular activated carbon (GAC), and granular clay-carbonaceous composite. Two types of bentonite-powder activated carbon-based granules (Ben-AC) were prepared within this work, with different calcination temperature. It was found that higher calcination temperature enhanced the surface porosity and adsorption potential versus studied micropollutants due to dihydroxylation resulting in higher chemical activity. Introduction of these granules in the place of GAC in a fixed bed column enhances the removal degree of micropollutants and typical water quality parameters. For example, the reduction degree of color, phosphate, and nitrate concentrations increased from 83%, 69%, and 4% to 95%, 83%, and 24% for column I and II, respectively. The concentration of carbamazepine, octylphenol, nononylphenol, and anthracene was reduced by 75%, 83%, 72%, 99% in column I, while using column II or III their removal was: 86%, 97%, 99%, 99%, respectively. Independent of the column filling, the removal of carbamazepine was the lowest (75–86%), while the highest retention was obtained for anthracene (99%). The study of column performance in the treatment of effluent in time showed that column filled with Ben-AC-400 guaranteed high removal degree in the operating time. The batch adsorption data were better described by both the Langmuir model.
