“…It gets contaminated during processing and its disposal affects the quality of natural reservoirs. Such quality deterioration of water would limit its applicability for domestic and agricultural purpose [3]. Hence treatment and purification of this water is highly essential before its application.…”

The porous membrane works upon sieving mechanism, where the separation and transport properties are dependent upon membrane morphology and porosity. This porosity and pore size are dependent upon membrane materials and formation parameters. Polysulfone (PSF) is one of the widely used membrane material due to its stability properties. Current work is targeted towards optimization of PSF based membranes by varying dope solution concentration and composition with the use of polyethylene glycol (PEG (MW6000)) as porogen in dope solution to enhance the transport rate and selectivity. An increase in PEG rejection with linear decrease in water flux and pore size was observed with the increase in dope solution concentration. Uniform membranes formation without any abnormal pore-size is observed from transport properties. The use of PEG as porogen leads to increased porosity due to leaching of Porogen during the phase inversion, which resulted in enhanced transport rate (85%). Further the formed membranes maintained pore size as seen from bubble point, rejection and pore size analysis. This resulted in maintenance of selectivity. Such increased transport with high selectivity is highly essential when applicability of membranes in industrial processes like process separation and waste treatment are considered. This would lead to large industrial benefits.

“…Reducing the consumption of antimicrobials is not sufficient to mitigate the release of AMR; therefore, an effective treatment technique is significantly needed. A variety of treatment techniques such as UV-C/H 2 O 2 and sunlight/H 2 O 2 (S. G. Michael et al 2020), ultraviolet disinfection (Wang et al 2020), oxidative damage (Zhang et al 2020), membrane filtration and 265 nm UV irradiation (Krzeminski et al 2020), and UVactivated persulfate (Zhou et al 2020) have been applied for the removal of antibiotics, antibiotic-resistant E. coli, and gene in wastewater. However, there is no particular treatment technique used for their treatment; it is, therefore, very significant to offer an efficient technique to remove them from wastewater.…”

“…They are not completely mitigated during treatment processes in sewage treatment plants; therefore, they can be distributed to the aquatic environment (Michael et al 2013;Rizzo et al 2013;Hembach et al 2019;Voigt et al 2020). Given this spread of ARGs in surface water and insufficient degradation in sewage treatment plants, antibiotic resistance poses a great threat to public health and to ecology (Krzeminski et al 2020;Thakali et al 2020;Voigt et al 2020). Furthermore, the World Health Organization (WHO), the United Nations (UN), and the European Union consider antimicrobial resistance (AMR) as a global public health threat (World Health Organization 2015; United Nations 2016; Krzeminski et al 2020).…”

Antibiotic resistance is considered by the countries to be a global health issue and a huge threat to public health. The reduction of resistant microorganisms from water/wastewater is of importance in environmental sciences since they are resistant in the aquatic environment. In this study, a bibliometric analysis of literature from the field of environmental science in water ecosystems from 2015 to 2019 was carried out using the keywords “Antibiotic Resistance (AR)” and “Escherichia coli”. Furthermore, using the keywords of “Fresh Water,” “Sea Water,” and “Waste Water,” 155, 52, and 57 studies were discovered, respectively. It is found that 217 studies of the total 2115 studies investigated on AR are mostly performed in the “Waste Water” by considering human health. Given the studies, an up-to-date solution should be proposed since the release of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) from wastewater treatment plants needs to be mitigated. For this reason, it is obvious that working on micro and macro ecosystems will increase the probability of solutions in antibiotic resistance. A discussion of removal techniques for coliform bacteria, particularly antibiotic resistant Escherichia coli, was presented. One of the unique values of this study is to offer an innovative solution that removing them by metal-organic frameworks (MOFs) are emerging crystalline hybrid materials. MOFs are used for environmental, biological, and food antimicrobial substances efficiently. Therefore, we can give inspiration to the future studies of antimicrobial resistance removal via adsorption using MOFs as adsorbents.

BACKGROUND For improving the permeability and selectivity of adsorption separation membranes, membrane materials, structural morphology and separation technology must continue to be investigated. Development of a membrane that is environmentally friendly, cost‐effective and with high filter precision is an important direction in current research. RESULTS The air pressure spraying method was used to prepare an activated carbon (AC)–cellulose acetate/chitosan (CA/CS) composite membrane. The CA/CS fiber composite membrane was prepared as substrate layer, and AC was loaded on the surface of the CA/CS composite membrane as a functional adsorption layer. When the spraying pressure was 0.01 MPa and the mass ratio of AC/CS was 2:1, a composite membrane with even and compact morphology could be obtained. Both the compact AC functional layer and complete CA/CS substrate layer endowed the AC–CA/CS composite membrane with an excellent water filtration property. At low feeding pressure, the permeate flux and rejection rate of bisphenol A (BPA) could reach 9.27 × 103 L m−2 h−1 and 98.31%, respectively. Meanwhile, the adsorption capacities of the membrane were investigated. It tended to equilibrate quickly in 2 min for dyes and BPA. The equilibrium adsorption capacities of the membrane for acid blue, acid yellow and BPA were 175.80, 164.0815 and 79.58 mg g−1, respectively. The adsorption process conformed to pseudo‐second‐order kinetics and the Langmuir monolayer adsorption model. CONCLUSIONS This work could provide a practical and effective feasibility for membrane separation technology. © 2020 Society of Chemical Industry (SCI)
