“…Reactive black 5, etc.). Lee et al (2013) fabricated reduced graphene oxide (rGO) nanoplatelets composite membrane (UF) for MBRs for wastewater treatment. It was reported that the GO membrane had anti-biofouling capability due to its hydrophilicity and electrostatic repulsion characteristics including superior mechanical strength and water permeability.…”

Application of polymeric membranes for the adsorption of hazardous pollutants may lead to the development of next-generation reusable and portable water purification appliances. Membranes for membrane adsorption (MA) have the dual function of membrane filtration and adsorption to be very effective to remove trace amounts of pollutants such as cationic heavy metals, anionic phosphates and nitrates. In this review article, recent progresses in the development of MA membranes are surveyed. In addition, recent progresses in the development of advanced adsorbents such as nanoparticles are summarized, since they are potentially useful as fillers in the host membrane to enhance its performance. The future directions of R&D in this field are also shown in the conclusion section.

“…In order to mimic polymer membrane fouling, various solutions are available such as traditional methods which involves physical cleaning via backwash (A process where permeate is used in flushing membrane backwards), relaxation (prior to filtration process), chemical cleaning of membrane using acids, caustic soda and hypochlorite, changing flow mode (cross flow filtration and low flux operation) and ultrasonic entrenchment prior to installation are some of the strategies to avoid fouling [49] 3 , Zeolite, Silver to form hybrid materials results in enhancement of membrane hydrophilicity, water flux, improved mechanical, selectivity, permeability, increase in salt rejection, chemical and thermal stability. Due to improvement in hydrophilicity of membrane and being cost effective, fabrication of membrane material using nano-materials is an easy and well-developed method [50][51][52][53][54]. Another way of mitigating fouling is flow configuration and flow velocity to prevent formation of cake layer on membrane surface due to foulants aggregation.…”

During last few decades, membrane technology has emerged as an efficient technique over conventional methods due to its high removal capacity, ease in operation and cost effectiveness for wastewater treatment and production of clean water. Membrane based separations are commonly based on polymeric membranes because of their higher flexibility, easily pore forming mechanism, low cost and smaller space for installation as compared to inorganic membranes. Commonly employed membrane fabrication phase inversion method has been shortly reviewed in this article. Major limitation of membrane based separations is fouling and polymeric membranes being hydrophobic in nature are more prone to fouling. Fouling is a deposition of various colloidal particles, macromolecules (polysaccharides, proteins), salts etc. on membrane surface and within pores thus impedes membrane performance, reduces flux and results in high cost. Modification of polymeric membranes due to its tailoring ability with nanomaterials such as metal based and carbon based results in polymeric nano-composite membranes with high antifouling characteristics. Nanomaterials impart high selectivity, permeability, hydrophilicity, thermal stability, mechanical strength, and antibacterial properties to polymeric membranes via blending, coating etc. modification methods. Characterization techniques has also discussed in later section for studying morphological properties and performance of polymer nano-composite membranes. Graphical Abstract

“…From these observations, it was evident that these membranes are potential candidates for waste water treatment. In a recent work, Lee et al [57] demonstrated that the inclusion of graphene oxide membranes in to the membrane bioreactor suppresses the fouling encountered during waste water treatment. Further, Lee et al [57] evidenced that the use of graphene oxide membrane overcame the fouling to a situation such that fivefold lengthening time witnessed between the chemical cleanings.…”

Further, Lee et al [57] evidenced that the use of graphene oxide membrane overcame the fouling to a situation such that fivefold lengthening time witnessed between the chemical cleanings. Moreover, it was very surprising to note that the inclusion of only 1 wt% graphene oxide during the synthesis of membrane is highly efficient to result in a novel membrane that can exhibit excellent anti-fouling capability for membrane bioreactors.…”

a b s t r a c tA perfect molecular level separating unit for any kind of species to be filtered is on very high demand. In recent years, graphene oxide has emerged as an important material which can filter ions and molecules. This is an emerging field of research which has drawn extensive attention after the work by Nair et al.[1]. Following their work, various research groups started working in this area in last three years. Herein, we briefly review the recent development on graphene oxide membranes. This review is a summary of some very recent results and contributions made so far in this emerging research field. We have discussed recently developed mechanisms and models to understand the transport through GO based membranes. This review begins with a basic background on membrane technology followed by discussion related to developments of carbon materials based membrane technology. At the end we summarize advantages and disadvantages of membranes based on graphene oxide and discuss their future prospective.
