“…110 If adsorption to the membrane is the main rejection mechanism, however, the presence of EfOM can also be detrimental. For example, Comerton et al 112 reported that the rejection of the hydrophobic compound gemfibrozil decreased in the presence of EfOM, which was attributed to competition for adsorption sites.…”

“…This occurs due to low estrone feed concentrations, where the amount of adsorption sites available on the membrane allows for adsorption of almost all the contaminant. High adsorption of xenobiotics have also been obtained in several UF studies [148,146,29]. Fluoranthene and 17β-estradiol adsorbs onto UF membranes from >70% for fluoranthene and >34% for estradiol [148].…”

“…Pore blockage by NOM also causes less access for adsorption sites, decreasing the rate of adsorption and therefore decreasing retention of xenobiotics. This has been shown to happen for steroid hormones, pharmaceuticals and pesticides [23,148,146,29]. …”

“…SMX is also more hydrophilic compared to other contaminants so sorptive interactions are not favoured [94]. As a general trend, the more hydrophobic the compound is the more it will adsorb on the membrane [66,148,93,95,146,29,147] since this requires less free energy compared to forming a "cavity" in the water phase [45]. It is argued that sorption interactions between the membrane and trace contaminants occur through H-bonding capacity which is lost for some contaminants when they dissociate (e.g.…”

Small molecular weight xenobiotics are compounds of extreme concern in potable water applications due to their adverse human health and environmental effects. However, conventional water treatment processes cannot fully and systematically remove them due to their low concentrations in natural waters and wastewaters. Biological limitation to degrade such compounds is another cause for inefficient removal.Physical barriers like membranes possessing pore sizes smaller than the compounds to be removed emerged as a good solution. Nanofiltration and reverse osmosis proved to be quite effective for xenobiotics removal in potable water production in the Paris purification plant of Méry-sur-Oise. However, even these very narrow pore membrane processes may result in incomplete removal: xenobiotics retention is high but factors such as adsorption, size exclusion and charge repulsion affect unpredictably their retention. The water solutions complexity to be treated renders xenobiotics removal predictions even more difficult due to interactions between xenobiotics and compounds in water.Removal of xenobiotics by microfiltration and ultrafiltration is very low because adsorption on the membrane is the main retention mechanism. Combining those with other processes (e.g. activated carbon) can considerably improve xenobiotics removal.The least studied processes in xenobiotics removal are electrodialysis, membrane distillation and pervaporation. Electrodialysis removal of organic xenobiotics shows a breakthrough through the membrane possibly due to adsorption followed by diffusion. Membrane distillation presents high removal rates of xenobiotics due to the compounds low vapour pressure. For volatile organic xenobiotics or solutions of trace amounts both membrane distillation and pervaporation can be used, xenobiotics interaction with the membrane being the key factor.In this book chapter a thorough synopsis of current knowledge on xenobiotics removal is presented and balanced with recent fundamental studies of underlying mechanisms, informing both the practitioner regarding membrane capabilities for xenobiotics removal and the researcher with the current state-of-art.

A series of novel polyacrylonitrile (PAN) adsorptive UF membranes were prepared via the nonsolvent induced phase inversion method using adsorbent-amphiphilic porous hollow carbonaceous microspheres (PHCSs) as additive. The resulted PAN/ PHCS membranes were demonstrated to have better mechanical strength than the pure PAN membrane. The water fluxes of the PAN/PHCS membranes were slightly decrease; however, the rejections to pepsin were maintained at a high level (81-86%). The properties of the PAN/PHCS membranes for 2,4-dichlorophenol removal from water were investigated. The results showed that 2,4dichlorophenol could be rapidly removed from water via adsorption mechanism by PAN/PHCS membranes, and the maximum reduction efficiency was up to 70%. The adsorption of 2,4-dichlorophenol to the membranes was reversible and the membranes could be regenerated facilely by water washing.
