“…2D reveals a RO membrane surface fouled by a common colloidal foulant, silica (Ho et al, 2016). In practice membrane fouling is usually caused by a combination of different foulants and membrane autopsy methods are widely used to study the origin and extent of membrane fouling and distribution of foulants because it can provide precise information about foulants compositions and properties (Gorzalski and Coronell, 2014;Kim et al, 2015;Tang et al, 2014;Tran et al, 2007). However, fundamental understanding of formation mechanism of fouling layer could not be obtained through autopsy.…”

“…It was known that different types of foulants and scalants were characterized in each RO elements according to its specific position within a pressure vessel [45,46]. Each RO element was autopsied for the extraction of the flat sheet membrane samples and the foulants accumulated on the membrane surfaces.…”

“…Various analysis helps to explanation the morphology of a fouled membrane surface and the identification and the distribution of organic/inorganic and biological components onto the membrane surface. While the membrane autopsies provide accurate information about the origin and the extent of foulants and fouling mechanisms, the more efficient membrane operation could be achieved by considering the membrane autopsy results (Kim et al 2015).…”

“…The results indicated that inorganic fouling was mainly formed calcium carbonate and aluminosilicates and operation under appropriate conditions and correct pretreatment increased the membrane lifespan. In another study, Kim et al (2015) performed a membrane autopsy of three fouled spiral wound, reverse osmosis membrane from different pressures vessel to identify the origin and extent of membrane fouling. The results showed that fulvic acid components from feed water was the main contributor of fouling.…”
