“…5, other common inorganic scalants include calcium phosphate, barium sulfate and so on. There are many factors which could affect inorganic scaling on membrane, such as membrane traits, compositions and features of feed water as well as operating conditions (Rabie et al, 2001;Shaalan, 2003). According to a study conducted by Lee et al (Lee et al, 1999), for unstirred batch membranes, surface (heterogeneous) crystallization plays a major role in flux decline, while for crossflow membranes, both surface crystallization and bulk (homogeneous) crystallization could cause scaling on the membranes.…”

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

“…In the past decade, numerous studies had been performed to investigate concentration polarization (CP), cake or gel layer formation, membrane pore blocking, and other fouling mechanisms on different membranes ( [20,21] and the reference cited therein). These studies suggested that membrane fouling due to inorganic salts is dependent on several factors, including but not limited to, membrane characteristics, module geometry, feed solution characteristics and operating conditions [22][23][24]. Moreover, several hypotheses have been introduced to explain the observed fouling behaviors.…”

“…Existing fouling indices are the Silt Density Index (SDI), Fouling Index (FI), Modified Fouling Index (MFI 0.45 ) and Plugging Index (PI) [4]. Among these methods, SDI is the most commonly used method in industry, but its limitations and unreliability have been demonstrated in several studies [5][6][7][8].…”
