“…7, this is probably because the grafted PVAm polymer tends to form a polymer brush layer, and the additional hydraulic resistance of the polymer brush layer is probably lower than that of the cross-linked PVA coating layer. This is consistent with the previous studies [24,30]. A promising speculation is that if the PVAm grafting method in this work is applied to the posttreatment of commercial RO membranes, smaller influence on the membrane water flux reduction might be seen compared with the traditional PVA coating process.…”

“…The PVA-coated membrane was also prepared on the TE membrane by the method in the previous study [24]. The PVA coating was performed by a dip coating method with 1.0 w/v% PVA aqueous solution, followed by heat treatment at 90°C for 10 min.…”

“…It can be seen from Table 2 that both the PVAm-grafted and the PVA-coated membranes have lower surface roughness than the TE membrane. This is probably because the PVAm or PVA polymer chains fill the valley structures on the RO membrane surfaces and the ridge-and-valley structures of the TE membrane are reduced [24]. Furthermore, the surface roughness of the PVAm-grafted membrane decreases with the increase of the mass concentration of the PVAm aqueous solution.…”

Reverse osmosis (RO) membrane technology is one of the most important technologies for water treatment. However, membrane fouling is an inevitable issue. Membrane fouling leads to higher operating pressure, flux decline, frequent chemical cleaning and shorter membrane life. This paper reviews membrane fouling types and fouling control strategies, with a focus on the latest developments. The fundamentals of fouling are discussed in detail, including biofouling, organic fouling, inorganic fouling and colloidal fouling. Furthermore, fouling mitigation technologies are also discussed comprehensively. Pretreatment is widely used in practice to reduce the burden for the following RO operation while real time monitoring of RO has the advantage and potential of providing support for effective and efficient cleaning. Surface modification could slow down membrane fouling by changing surface properties such as surface smoothness and hydrophilicity, while novel membrane materials and synthesis processes build a promising future for the next generation of RO membranes with big advancements in fouling resistance. Especially in this review paper, statistical analysis is conducted where appropriate to reveal the research interests in RO fouling and control.Graphic Abstract

Nanotechnology-based coatings have shown remarkable growth in recent years in many strategic industries such as automotive, aerospace, petroleum, electronics, etc. The unique characteristics that can be offered from nanotechnology are one of the main driving forces for the sharp innovation in coatings technology nowadays. Nanocoatings have recently been proposed to add functionalities to the materials to be coated such as anticorrosion self-healing, anti-icing, self-cleaning, etc. Different types of nanomaterials have been incorporated in anticorrosion coatings by adopting various approaches. The basic approach utilizes incorporation of inorganic nanomaterials with the traditional organic coatings to enhance certain functionality of the formulated nanocomposite coating. However, one of the recent trends in nanotechnology is to design nanomaterial-based coatings of multifunctionality. These include stimuliresponsive/smart coatings, self-healing coatings, organic/inorganic hybrid coatings, and electroactive coatings. This chapter highlights these emerging nanotechnologies and presents the most recent achievements in this area.
