“…The surface area of the produced membranes is 14.45 cm 2 and the dead-end filtration setup in Figure 1b was used. After the membranes were compressed at 6 bars, pure water fluxes were taken at 5 bars for 1 h. To examine the removal efficiency of salt performance of the membrane after the pure water flow, 2000 ppm MgSO 4 and 2000 ppm NaCl solution was prepared, and the fluxes were taken at 5 bar for 1 h. The calculation of fluxes is computed using Equation (2). For calculating the salt removal efficiency, the feed and permeate conductivity were determined and calculated using Equation (3).…”

Hollow fiber membranes have higher surface area and are easy to be applied in systems. Because of theirs self‐supporting construction, they have limited mechanical durability. By reinforcing these membranes with a braid, the mechanical strength can be improved. In this study, the impact of polyvinyl pyrrolidone (PVP) as a pore‐forming additive with different contents on the fabrication of polysulfone braid reinforced hollow fiber membranes was investigated both as a ultrafiltration membrane and as a support for the fabrication of thin film composite (TFC) nanofiltration membranes. Characterization and filtration studies of all membranes were performed to examine membrane performance. It was discovered that the porosity and hydrophilicity of the ultrafiltration membranes were enhanced by enhancing PVP concentration, thus increasing the pure water flux in the membranes. As regards to results of fabricated TFC membranes, salt rejections were increased with increasing PVP ratios. The rejection efficiency of magnesium sulfate and sodium chloride was found to be approximately 80% and 49%, respectively, when a PVP ratio of 8% was used.

“…Among the biological processes, it is possible to enumerate the following as examples: activated sludge [ 130 ], microalgae treatment [ 131 ], biofiltration [ 132 ], and constructed wetlands [ 133 ]. Photoreaction can also be used to eliminate some pharmaceuticals, as reviewed by Abd Rahman, Choong [ 134 ], as well as filtration/adsorption processes [ 135 , 136 ] and advanced oxidation processes [ 137 ]. In this review, these strategies will not be discussed in detail since it is possible to find a vast number of recent review articles describing different strategies to remove pharmaceuticals and ECs in general [ 131 , 132 , 133 , 134 , 135 , 136 , 137 ].…”

Pharmaceuticals are present as pollutants in several ecosystems worldwide. Despite the reduced concentrations at which they are detected, their negative impact on natural biota constitutes a global concern. The consequences of pharmaceuticals’ presence in water sources and food have been evaluated with a higher detail for human health. However, although most of the pharmaceuticals detected in the environment had not been designed to act against microorganisms, it is of utmost importance to understand their impact on the environmental native microbiota. Microbial communities can suffer serious consequences from the presence of pharmaceuticals as pollutants in the environment, which may directly impact public health and ecosystem equilibrium. Among this class of pollutants, the ones that have been studied in more detail are antibiotics. This work aims to provide an overview of the impacts of different pharmaceuticals on environmental biofilms, more specifically in biofilms from aquatic ecosystems and engineered water systems. The alterations caused in the biofilm function and characteristics, as well as bacteria antimicrobial tolerance and consequently the associated risks for public health, are also reviewed. Despite the information already available on this topic, the need for additional data urges the assessment of emerging pollutants on microbial communities and the potential public health impacts.

The escalating incidence of chronic diseases and infections has driven an increase in the use of antibiotics, raising concerns regarding their disposal and presence in water sources. Antibiotic‐resistant genes (ARGs) can arise in bacteria and other microorganisms when antibiotics are present in the water. Human, plant, and animal physiological processes may be negatively impacted by extended exposure to these substances. Since MXenes are effective photocatalysts and adsorption agents, they have garnered a lot of attention in the wastewater treatment industry. While employing MXene alone typically yields inadequate results, it is advantageous to combine MXene with other materials to generate derivatives or composites. This comprehensive review meticulously examines MXene composites with various materials to enhance their photocatalytic prowess, unveiling composite systems capable of achieving an exceptional degradation efficiency of up to 99%, as exemplified by the UiO‐66/MXene composite and g‐C3N4/Ti3C2 MXene/black phosphorus heterojunction. Additionally, this paper provides critical insights into the intrinsic characteristics, synthesis methodologies, and performance efficiencies for these composites, thereby serving as an invaluable resource for researchers and practitioners in the field.
