“…Their presence has consistently been detected at low concentrations in the majority of cases (i.e., ng L −1 -µg L −1 ) [6]. However, even at trace concentrations, when in contact with living organisms, CECs may induce the above-mentioned adverse effects, including decreased fish reproduction caused by endocrine system disruption, reduced invertebrate populations due to sublethal toxicity, and the spread of antibiotic-resistant bacteria (ARB) and antibiotic-resistant genes (ARGs) [17,18,27].…”

The occurrence of contaminants of emerging concern (CECs) in several environmental compartments has raised significant concern given the extensive array of compounds and their consistent detection across various environmental matrices. Monitoring all potentially harmful compounds and identifying their sources is nearly impossible. However, providing data on their occurrence is crucial and lays the groundwork for decision makers to craft mitigation strategies toward a more sustainable water policy. Hence, the primary aim of this study was to conduct an evaluation study on CECs occurrence in the environment. The main novelty relies on understanding their specific pathway in three different environmental aquatic compartments. For that, a combined study of a systematic review and systemic analysis was performed. Initially, the five most common types of CECs found in aquatic ecosystems (groundwater and surface water) and wastewater were considered. For each group of CECs, five contaminants were identified. A bibliographic portfolio was generated through the application of a systematic review. Finally, a systemic analysis of the bibliographic portfolio was conducted. All classes of contaminants studied were identified in the environmental compartments evaluated. Except for pesticides, the degree of contamination by CECs followed a sequence based on the aquatic compartment (i.e., WW–SW–GW).

“…New membrane-based technologies and alternative treatment schemes are being proposed to transform the former concept of wastewater treatment plants (WWTP) into new resource recovery facilities, such as membrane photobioreactors [ 5 , 6 ], anaerobic membrane bioreactors [ 7 ] (also including alternative treatment platforms and configurations [ 8 ]) and other advanced systems for water and nutrient recovery [ 9 , 10 , 11 ]. Moreover, produced water quality is being improved by emerging MWW tertiary treatment for effectively removing antibiotics and other emerging contaminants, such as photodriven advanced oxidation and photocatalysis [ 12 , 13 , 14 ]. Among the new MWW treatment alternatives, direct filtration of MWW, commonly referenced by the scientific community as direct membrane filtration (DMF), has recently gained increasing interest [ 15 ].…”

Direct Membrane Filtration of Municipal Wastewater: Studying the Most Suitable Conditions for Minimizing Fouling Rate in Commercial Porous Membranes at Demonstration Scale

et al. 2023

This study aimed to evaluate the feasibility of applying a commercial porous membrane to direct filtration of municipal wastewater. The effects of membrane pore size (MF and UF), treated influent (raw wastewater and the primary settler effluent of a municipal wastewater treatment plant) and operating solids concentration (about 1 and 2.6 g L−1) were evaluated on a demonstration plant. Filtration periods of 2–8 h were achieved when using the MF membrane, while these increased to 34–69 days with the UF membrane. This wide difference was due to severe fouling when operating the MF membrane, which was dramatically reduced by the UF membrane. Use of raw wastewater and higher solids concentration showed a significant benefit in the filtration performance when using the UF module. The physical fouling control strategies tested (air sparging and backwashing) proved to be ineffective in controlling UF membrane fouling, although these strategies had a significant impact on MF membrane fouling, extending the operating period from some hours to 5–6 days. The fouling evaluation showed that a cake layer seemed to be the predominant reversible fouling mechanism during each independent filtration cycle. However, as continuous filtration advanced, a large accumulation of irreversible fouling appeared, which could have been related to intermediate/complete pore blocking in the case of the MF membrane, while it could have been produced by standard pore blocking in the case of the UF membrane. Organic matter represented more than 70% of this irreversible fouling in all the experimental conditions evaluated.

“…As the pore size becomes smaller or the molecular weight cut-off decreases, the pressure applied to the membrane for the separation of water from other material generally increases. The water treatment objectives will determine the basis on which a process is selected [26][27][28][29].…”

This manuscript presents the advances of a pilot testing, located in Spain, using ultrafiltration (UF) membranes to supply drinking water. These results could be extended to the islands of the Macaronesia area, for instance, Azores, Madeira, Canaries, and Cape Verde. The UF project targeted by the pilot activity is a refurbishment of an existing installation. The existing installation is located at a higher altitude, thus drinking water could be supplied to most of the island without further pumping, reducing the carbon footprint, ecological footprint, and energy consumption. The raw water is soft surface water (mainly of rainwater origin) coming from a dam. On the islands of Macaronesia, water is a scarce resource in high demand. Therefore, this is a technically and economically viable business opportunity with a promising future for isolated water treatment systems to produce drinking water on islands. The Macaronesia area is formed by volcanic islands with a small surface in the Atlantic Ocean, so usually there is not enough space for conventional technology and only a compact UF can be used. The raw water quality is not satisfactory and the municipality receives many complaints from end users, thus a potable water plant with UF membranes is in high demand to supply drinking water of good quality. Membrane processes can be categorized into various, related methods, three of which include the following: pore size, molecular weight cut-off, and operating pressure. Regarding the obtained results, the UF system successfully produced excellent filtrate quality with turbidity readings on average less than 0.03 NTU; furthermore, membrane instantaneous flux of 90 Lmh at 14 °C is achievable with long-term stability under various feed water conditions, peak operations are available at 105 Lmh without a large impact on the filtration performance of the modules, and CIP is only to be performed if the TMP increase reaches the terminal point.
