“…PDA, a thin and adhesive film inspired by the Mytilus edulis foot, is produced by DA self-polymerization under alkaline condition with oxygen, and it has been widely used in surface modification [19][20][21][22]. It was found that the addition of low molecular-weight polyethyleneimine (PEI, 600 Da) could promote the homogeneous polymerization and deposition of DA [23], and even a NF membrane could be prepared by the co-deposition of DA/PEI on a UF membrane followed by crosslinking, which exhibited a high rejection for multivalent cations [24].…”

“…Some heavy metal like Pb, Mo, etc. organic and inorganic pollutants and various harmful microbes are reported to be successfully removed by using different nanomaterials [12][13][14][15][16]. Currently, WHO (World Health Organization) reported that almost 1.7 million people died due to water pollution and four billion cases of different health issues were reported annually due to waterborne diseases [17].…”

Water is an essential part of life and its availability is important for all living creatures. On the other side, the world is suffering from a major problem of drinking water. There are several gases, microorganisms and other toxins (chemicals and heavy metals) added into water during rain, flowing water, etc. which is responsible for water pollution. This review article describes various applications of nanomaterial in removing different types of impurities from polluted water. There are various kinds of nanomaterials, which carried huge potential to treat polluted water (containing metal toxin substance, different organic and inorganic impurities) very effectively due to their unique properties like greater surface area, able to work at low concentration, etc. The nanostructured catalytic membranes, nanosorbents and nanophotocatalyst based approaches to remove pollutants from wastewater are eco-friendly and efficient, but they require more energy, more investment in order to purify the wastewater. There are many challenges and issues of wastewater treatment. Some precautions are also required to keep away from ecological and health issues. New modern equipment for wastewater treatment should be flexible, low cost and efficient for the commercialization purpose.

“…In recent years, membrane separation technology with its inherent characteristics of high efficiency, no phase change, space saving, and easy operation has emerged as an effective and promising method for the treatment of heavy metal ions wastewater, especially ultrafiltration (UF) and reverse osmosis (RO) process. In UF processes, although the dissolved metal ions are much smaller than pore sizes of the corresponding membranes, the ions still can be rejected by polymer enhanced ultrafiltration (PEUF) or micellar enhanced ultrafiltration (MEUF) via surface modification.…”

Nanofiltration (NF) membranes have been widely used for the treatment of electroplating, aerospace, textile, pharmaceutical, and other chemical industries. In this work, halloysite nanotubes (HNTs) were directly anchored on the surface of commercial nanofiltration (NF) membrane by dopamine modification following advantageous bio‐inspired methods. SEM and AFM images were used to characterize the HNTs decorated membrane surface in terms of surface morphology and roughness. Water contact angle (WCA) was employed in evidencing the incorporation of HNTs and dopamine in terms of hydrophilicity or hydrophobicity. Augmentation of HNTs was found to obviously enhance the hydrophilicity and surface roughness resulting in improved water permeability of membrane. More importantly, the rejection ratios of membrane also increased during the removal of heavy metal ions from wastewater. The permeability and Cu2+ rejection ratio of modified NF membrane were as high as 13.9 L·m−2·h−1·bar−1 and 74.3%, respectively. Incorporation of HNTs was also found to enhance the anti‐fouling property and stability of membrane as evident from long‐term performance tests. The relative concentration of HNTs and dopamine on membrane surface was optimized by investigating the trade‐off between water permeability and rejection ratio.
