“…Membrane scaling has been studied via permeate flux decline measurements [8][9][10], as well as acoustic detection [11,12] and direct surface observations [11,13] using commercial RO/NF membranes. The majority of commercial RO/NF membranes are thin-film polyamide membranes and thus studies of mineral scaling have been limited to polyamide surfaces [14,15], with a few studies also considering cellulose acetate surfaces [16,17]. It has been shown that the membrane surface topography [18] and chemistry [19][20][21] can affect mineral salt scaling process significantly.…”

“…RO is currently the most energy-efficient technology for desalination, with energy cost about 1.8 kWh/m 3 , which is much lower than that of other technologies (G. R. . Also, RO membrane has the advantages of high water permeability and salt rejection, fulfillment of the most rigorous rules for public health, environmental protection and separation process (López-Ramírez et al, 2006).…”

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

“…The RO water treatment method has been used comprehensively to convert brackish or seawater to drinking water (18)(19)(20)(21), to clean up wastewater (22)(23)(24), and to recover and treat water from industrial processes (25)(26)(27)(28)(29). Nowadays, RO is becoming more popular as the household water treatment method for the direct consumption of water, such as for drinking and cooking purposes.…”

Point-of-use (POU) system is the treatment process aimed to treat only water intended for direct consumption (drinking and cooking), typically at a single tap or limited number of taps. Point-of-entry (POE) treatment devices are typically installed to treat all water entering a single home, business, school, or facility. Reverse osmosis (RO) is recognized by the industry as one of the top POU and POE treatment technologies. This chapter describes the advantages and limitations in using RO for POU and POE applications. Types and configurations of reverse osmosis, and installation, operation and maintenance, and testing of RO are also included.
