“…Increasing the temperature of the feed water can cause an increase in the osmotic pressure of the feed water, which can lead to a reduction in water flux through the membrane. This can result in reduced efficiency of the RO process (Ghazal et al, 2022).…”

Once pharmaceutical wastes are released into the sewage network, antibiotics can have several negative effects, such as promoting the development of antibiotic-resistant bacteria and disrupting natural microbial communities in water bodies. Linezolid is particularly concerning because it is a broad-spectrum antibiotic that targets a wide range of bacteria, including those resistant to other antibiotics. This means that linezolid may be more likely to contribute to the decreasing the huge number of strains of bacteria in the environment, that are used to decrease BOD values in wastewater streams. Linezolid is manufactured at many sites in Egypt, the study was started at the end of 2021, and it continued until the first quarter of 2022, in a pharmaceutical factory located in El Obour city. In this work, Reverse Osmosis (RO) is used to remove pharmaceutical pollutants such as linezolid antibiotics from waste that is drained of the pharmaceutical facility. The Results show that RO can remove significant amounts of linezolid from wastewater, with removal efficiencies ranging from 78% to 95%. The removal efficiency is affected by several factors. The factors under investigation are temperature, initial concentration of the pollutant (linezolid antibiotic), conductivity, and the total hardness of the influent of the wastewater. The maximum removal efficiency was discussed according to the optimum parameter, temperature 26 Cº, initial concentration 3 ppb, conductivity 500 µS/cm, and finally the optimum total hardness was obtained

“…Various treatment techniques have been reported and established for wastewater remediation, including sedimentation [14,15], filtration [16,17], biofilms [18,19] and activated sludge [20,21]. However, these existing techniques encounter challenges in completely removing non-biodegradable pollutants due to constraints such as high chemical and energy consumption, prolonged reaction time, high operating costs, sludge generation and toxic gas release [22,23]. Therefore, semiconductor-based photocatalysts have drawn significant attention for wastewater remediation due to their capability to efficiently remove pollutants, transforming them into harmless by-products under light irradiation [24][25][26][27].…”

Water pollution has emerged as a significant worldwide issue, with organic pollutants being a key contributor. Titanium dioxide (TiO2) has demonstrated promising photocatalytic performance in removing organic pollutants under ultraviolet (UV) irradiation. However, the wide band gap (3.2 eV) of TiO2 results in low absorption capacity of visible light, hindering its overall efficiency in degrading organic pollutants. To address the limitation, this research aimed to synthesize visible light-driven TiO2 photocatalyst with different polymorphs (anatase and rutile) and investigate the effect of various doping combination (Nb, B and Nb,B) and concentrations (0.25, 0.50, 0.75 and 1.00 mol%) on the photodegradation efficiency towards methylene blue (MB) dye solution. Anatase phase was obtained when TiO2-based nanopowders were calcined at 400 °C, while the rutile phase was formed at 900 °C based on XRD analyses. Additionally, the morphology analyses revealed that the particle size of anatase is much smaller than that of rutile. The presence of dopants further reduced the particle size of both anatase and rutile phases. Based on UV-Vis absorbance spectra analyses, the anatase Nb,B-TiO2 with 0.50 mol% of dopant concentration exhibited the best photocatalytic performance towards MB. Moreover, the anatse phase of 0.50 mol% Nb,B-TiO2 showed the narrowest band gap of 2.74 eV compared to the TiO2 (3.4 eV), representing a reduction of 19.41 %, according to UV-Vis analyses. These outcomes suggest the potential application of anatase phase of 0.50 mol% Nb,B-TiO2 in treating organic pollutants in wastewater under visible light conditions in future.

“…In recent years, there has been increased interest in the possibility of using various types of membranes to remove ECs and synthetic dyes from wastewater. In principle, membrane-based processes are considered more environmentally friendly than many traditional methods of removing these pollutants [ 21 , 22 ]. One type of liquid membranes (LMs) are polymer inclusion membranes, containing a polymer matrix, carrier, and most often a plasticizer, the use of which enables simultaneous extraction and re-extraction.…”

The Application of Polymer Inclusion Membranes for the Removal of Emerging Contaminants and Synthetic Dyes from Aqueous Solutions—A Mini Review

2023

Pollution of the environment, including water resources, is currently one of the greatest challenges due to emerging new contaminants of anthropogenic origin. Of particular concern are emerging organic pollutants such as pharmaceuticals, endocrine disruptors, and pesticides, but also other industrial pollutants, for example, synthetic dyes. The growing demand for environmentally friendly and economical methods of removing emerging contaminants and synthetic dyes from wastewater resulted in increased interest in the possibility of using techniques based on the application of polymer inclusion membranes (PIMs) for this purpose. PIM-based techniques are promising methods for eliminating emerging contaminants and synthetic dyes from aqueous solutions, including wastewater, due to high efficiency, membranes versatility, ease/low cost of preparation, and high selectivity. This review describes the latest developments related to the removal of various emerging contaminants and synthetic dyes from aqueous solutions using PIMs over the past few years, with particular emphasis on research aimed at increasing the effectiveness and selectivity of PIMs, which may contribute to wider use of these methods in the future.
