“…[3] However, a problem inevitably presented in the MF system involving the emulsion droplets to serve as rigid particles, [4] entering the pore of MF membrane or accumulating on the surface could greatly deteriorate the outcome of emulsion separation. [5] Meanwhile, the higher flux of MF membrane at the initial stage of emulsion separation process implies that more emulsion droplets are left on the surface of MF membrane and are readily available to form the fouling layer, substantially inhibiting continuous water permeation. [3d,e,6] Therefore, the rational design of MF membrane with high flux and antifouling ability is urgently demanded for broadening the utilization of MF technology for purification of emulsified oily wastewater.…”

The development of microfiltration (MF) membranes with a high separation flux and antifouling ability is an ultimate goal for the purification of emulsified oily wastewater by MF techniques. Herein, a dual‐functional MIL‐100(Fe)@graphene oxide (MIL‐100(Fe)@GO) membrane is fabricated by in situ growth of MIL‐100(Fe) with a graphene oxide (GO) nanosheet. The porous MIL‐100(Fe)@GO composite endows the MF membrane with superhydrophilicity and demulsification functions. The MIL‐100(Fe)@GO membrane achieves an outstanding water permeation flux of 12 457 L m−2 h−1 bar−1, as encouraged by the versatility of MIL‐100(Fe) in enabling superhydrophilicity of the MIL‐100(Fe)@GO membrane and providing rich water permeation channels. An impressive emulsion separation efficiency of >99% and maximum emulsion separation flux of 5529 L m−2 h−1 bar−1 are thus delivered by the MIL‐100(Fe)@GO membrane. Moreover, a 131% recovery ratio of emulsion separation flux (7135 L m−2 h−1 bar−1) is attained with this system after regeneration by ethanol. In virtue of the demulsification of MIL‐100(Fe), the rational design of the MIL‐100(Fe) hybrid membrane exhibits a self‐cleaning effect on the emulsion separation. The demonstrated high performance of the membrane system opens up new avenues for the development of membranes with antifouling abilities and ultrahigh flux for emulsion separation.

“…These nanomaterials might also provide additional antibacterial, antifouling and photocatalytic activity, which opens a new path to ultra-fast and highly selective membranes for water purification [78]. A number of well-studied antimicrobial nanomaterials include titanium oxide [79], gold (Au), zinc oxide (ZnO), silver (Ag), carbon nanotube (CNT), graphene, and graphene oxide [80], have been utilized in various type of membrane-based water treatment system. The advances in nanotechnology and engineered nanomaterials presented a leapfrogging prospect to the next-generation membrane-based water treatment systems with a more affordable price and better purification efficiency.…”

Fulfilling the demand of clean potable water to the general public has long been a challenging task in most developing countries due to various reasons. Large-scale membrane water treatment systems have proven to be successful in many advanced countries in the past two decades. This paves the way for developing countries to study the feasibility and adopt the utilization of membrane technology in water treatment. There are still many challenges to overcome, particularly on the much higher capital and operational cost of membrane technology compared to the conventional water treatment system. This review aims to delve into the progress of membrane technology for water treatment systems, particularly in developing countries. It first concentrates on membrane classification and its application in water treatment, including membrane technology progress for large-scale water treatment systems. Then, the fouling issue and ways to mitigate the fouling will be discussed. The feasibility of membrane technologies in developing countries was then evaluated, followed by a discussion on the challenges and opportunities of the membrane technology implementation. Finally, the current trend of membrane research was highlighted to address future perspectives of the membrane technologies for clean water production.

“…Over the past years, graphene and its derivatives, specifically graphene oxide (GO), has captured the attention of many researchers in the field of membranes for water treatment owing to its superb thinness and distinguishable layered structure. These unique features increase the permeation fluxes and enhance the hydrophilic and physicochemical properties, making it excellent for oil/water separation [ 67 ]. Table 2 below shows the performance of several graphene-based membranes in oil/water mixtures.…”

The vast demand for petroleum industry products led to the increased production of oily wastewaters and has led to many possible separation technologies. In addition to production-related oily wastewater, direct oil spills are associated with detrimental effects on the local ecosystems. Accordingly, this review paper aims to tackle the oil spill cleanup issue as well as water separation by providing a wide range of graphene-based technologies. These include graphene-based membranes; graphene sponges; graphene-decorated meshes; graphene hydrogels; graphene aerogels; graphene foam; and graphene-coated cotton. Sponges and aerogels modified by graphene and reduced graphene oxide demonstrated effective oil water separation owing to their superhydrophobic/superoleophilic properties. In addition, oil particles are intercepted while allowing water molecules to penetrate the graphene-oxide-coated metal meshes and membranes thanks to their superhydrophilic/underwater superoleophobic properties. Finally, we offer future perspectives on oil water separation that are hindering the advancements of such technologies and their large-scale applications.
