“…It is linked to the idea for membrane processes to substitute conventional energy intensive separation techniques enabling sustainable industrial growth. The compatibility between various membrane operations in hybrid systems, the good stability under operative conditions, and the environmentally compatible aspect are crucial for better rational utilization and feed recovery (Drioli andGiorno, 2009, Martini andSetiawati, 2021).…”

“…The hybrid of adsorption and membrane systems has been considered effective to improve membrane performance by reducing pollutants contained in the feed as adsorption is mostly put at the first stage as pretreatment as displayed in figure 2. For different membrane types like reverse osmosis, nanofiltration (NF), ultrafiltration (UF), and micro-filtration (MF), their integration to various inorganic and organic adsorbents like activated carbon (AC), zeolite, graphene, carbon nanotubes bsed-sorbents or iron oxy/ hydroxide based-biochars, and metal-organic frameworks have shown positive outcome lowering membrane workloads leading to lower flux profile decrease (Xu et al, 2017, Martini andSetiawati, 2021).…”

Current development of membrane technology for purifying polluted water and wastewater is discussed in this review in accordance with its hybrid application with other types of water treatment methods such as adsorption, advanced oxidation processes (AOPs), and biological activated sludge. This hybrid implementation aims are to lengthen membrane lifespan and elude severe fouling on the surface and pore of the membrane. Membrane material and fabrication technology were concisely included. Two prominent materials to fabricate membrane namely polymeric and ceramic are reviewed well along with the exploration of biopolymers based-materials such as starch and alginate. Several fabrication methods available to be implemented in research or industrial large scale including interfacial polymerization technique, non-solvent induced phase separation, temperature induced phase separation, electrospinning, and sintering are deliberately discussed. The next section includes fouling analysis involving reliable fouling mechanism namely Hermia’s models to help with the explanation of fouling occurrence during filtration. These models covers four different mechanisms namely complete blocking, standard blocking, intermediate blocking, and cake filtration models. Ultimately, recent research reporting the outcome of the hybridization of membrane and adsorption, biosorption, coagulation-flocculation, AOPs, and biological treatment using microorganism were properly reviewed. Overall, this review considerably promotes the findings of those works which mostly revealed positive outcome of the hybrid membrane system contributing to stronger foundation for future research.

Oil–water separation technology has potential applications in wastewater treatment, petroleum refining and edible oil processing. As the ultimate means in oil-water treatment, electrostatic coalescence technology has been widely used in oil fields and refineries. However, the technology has many problems, such as complex processes, electrode corrosion, and the inability to treat high-water-cut crude oil emulsions. Here, we propose a contactless method of oil-water separation by corona discharge. With corona discharge of a needle–plate electrode configuration, the oil droplet diffuses to the ITO glass surface and the water droplet oscillates at the edge of the PET film. Here, such droplet behaviors are described in detail. Based on the motion behavior of the oil and water droplet, we designed an efficient oil-water separation device. After the oil-water mixture passes through the device, the oil content in the oil region can reach 99.25% with a voltage of 8 kV. In addition, the separation speed of the oil-water mixture can also be adjusted by varying the corona discharge voltage. This paper presents a simple and innovative method for oil-water separation.
