“…Membrane separation, a highly efficient, environmentally friendly, and multi-disciplinary technology, entails various characteristics of the physical, chemical, and biological processes, and has many advantages [12][13][14]. The technology takes advantage of the difference in molecular size of the species in different solutions, uses a polymer membrane as the medium, and relies on concentration differences or external energy as the driving force to separate and purify the required substances [15,16].…”

“…The biological methods [10,11] include the traditional activated sludge method and anaerobic methods, in which the cultivation of functional strains is slow and inefficient, the treated water is difficult to recycle, and secondary pollution is often produced.

Forward osmosis (FO) is an evolving membrane separation technology for water treatment and reclamation. However, FO water treatment technology is limited by factors such as concentration polarization, membrane fouling, and reverse solute flux. Therefore, it is of a great importance to prepare an efficient high-density porous membrane and to select an appropriate draw solute to reduce concentration polarization, membrane fouling, and reverse solute flux. This review aims to present a thorough evaluation of the advancement of different draw solutes and membranes with their effects on FO performance. NaCl is still widely used in a large number of studies, and several general draw solutes, such as organic-based and inorganic-based, are selected based on their osmotic pressure and water solubility. The selection criteria for reusable solutes, such as heat-recovered gaseous draw, magnetic field-recovered MNPs, and electrically or thermally-responsive hydrogel are primarily based on their industrial efficiency and energy requirements. CA membranes are resistant to chlorine degradation and are hydrophilic, while TFC/TFN exhibit a high inhibition of bio-adhesion and hydrolysis. AQPs are emerging membranes, due to proteins with complete retention capacity. Moreover, the development of the hybrid system combining FO with other energy or water treatment technologies is crucial to the sustainability of FO.

“…In recent decades, pharmaceuticals and personal care products have been widely used around the world, and their continued release and corresponding metabolites have caused varying degrees of environmental pollution [ 3 , 4 ]. Different technologies for the elimination of hazardous chemicals from water [ 5 , 6 ], which include absorption, adsorption, distillation and membranes, have been developed. The selection of wastewater treatment systems depends on factors such as the method’s flexibility, process costs or the process’s environmental compatibility [ 7 ].…”

Present research was directed towards the development of new high-performance and cost-effective polysulfone membranes (PSFQ) by introducing ionic liquids (ILs—Cyphos 101 IL and Aliquat 336) into their matrix. Variation of ILs was performed with the aim to find the one that brings new properties and improves the functionality and selectivity of PSFQ membranes in ultrafiltration processes. Based on the obtained results of the rheological study, we established the compatibility of compounds and optimal content of the used ILs, namely 3 wt% and 15 wt% Cyphos 101 IL and compositions varying between 3 and 15 wt % Aliquat 336. Results indicated that the ILs acted as plasticizers when they were added to the system, a helpful aspect in processing membranes used in water decontamination. The efficiency and performance of the membranes were evaluated by their use in the treatment of diclofenac (DCF)-containing waters. Membranes obtained from PSFQ/Aliquat 336 solution containing 15 wt% IL exhibited a 97% removal degree of DCF in the treatment process of 50 mL solution containing 3 mg/L DCF. The separation efficiency was kept constant for four filtration/cleaning cycles. The results indicated an improvement in membrane performance as the amount of IL in their structure increased, which confirms the potential for application in water treatment processes.

“…Therefore, wastewater treatment has become an extremely important element in the management of environmental problems. Wastewater treatment technology has evolved to include electrolysis ( Li et al, 2014 ), incineration ( Cai et al, 2020 ), membrane separation ( Ahmad et al, 2021 ), deep well injection ( Hongkun and Lin, 2007 ) and biological treatment ( Velvizhi and Venkata Mohan, 2015 ; Kong et al, 2019 ). Each of these five treatment methods has its advantages and disadvantages: electrolysis is highly adaptable and can efficiently treat a wide range of wastewaters ( G ao et al, 2006 ), with the disadvantage of higher costs ( Hong, 2001 ); incineration is simple to implement and has a high treatment rate, with the disadvantage that the treatment effect is greatly influenced by the concentration of organic matter in the wastewater, and incineration itself is only suitable for treating wastewater with high concentrations of organic matter, while in treating wastewater with low concentrations of organic matter it is necessary to adjust the pH value of the wastewater, add fuel ( Wei et al, 2008 ) and bring about combustion ( Jiehong, 2010 ).…”

In recent years, photocatalytic microbial fuel cells have gradually become a hot research topic in pollutant treatment, using either in situ or indirectly the oxidation of organic pollutants by catalytic materials under light and the biodegradation and mineralization of various components in wastewater by microorganisms, or through the generation of electricity by the microbial fuel cell (MFC) system to promote the photogeneration and separation of electrons and holes by the catalytic materials of the photocatalytic cell (PC) system. This study aims to provide new ideas for the development of environmentally friendly wastewater treatment technologies by investigating the use of photocatalytic cells for the efficient degradation and resource utilization of target pollutants. This study aims to raise awareness of the use of photocatalytic microbial fuel cells for pollutant degradation by providing an overview of the practical status of photocatalytic microbial fuel cells. This is achieved by reviewing the key cathode development, production capacity, and progress in the degradation of pollutants in photocatalytic microbial fuel cells. The issues facing future developments are also discussed in terms of how photocatalytic microbial fuel cells work and how they degrade pollutants. This study shows that photocatalytic microbial fuel cells are beneficial for achieving renewable energy (bioenergy, photovoltaic, etc.) capacity and dealing with environmental pollution and that this is a novel technology that deserves to be promoted to achieve the current dual carbon targets.
