“…Various fields can be applied in FFF depending on the nature of the material to be analyzed including flow field-flow fractionation (FlF-FF), thermal (ThFFF), electrical (ElFFF), sedimentation (SdFFF), gravitational (GrFFF), dielectrophoretic (DEP-FFF), acoustic (AcFFF) and magnetic (MgFFF) field-flow fractionation [134]. Further details on these techniques can be found elsewhere [134,135].…”

Various membrane separation processes are being used for seawater desalination and treatment of wastewaters in order to deal with the worldwide water shortage problem. Different types of membranes of distinct morphologies, structures and physico-chemical characteristics are employed. Among the considered membrane technologies, membrane distillation (MD), osmotic distillation (OD) and osmotic membrane distillation (OMD) use porous and hydrophobic membranes for production of distilled water and/or concentration of wastewaters for recovery and recycling of valuable compounds. However, the efficiency of these technologies is hampered by fouling phenomena. This refers to the accumulation of organic/inorganic deposits including biological matter on the membrane surface and/or in the membrane pores. Fouling in MD, OD and OMD differs from that observed in electric and pressure-driven membrane processes such electrodialysis (ED), membrane capacitive deionization (MCD), reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), microfiltration (MF), etc. Other than pore blockage, fouling in MD, OD and OMD increases the risk of membrane pores wetting and reduces therefore the quantity and quality of the produced water or the concentration efficiency of the process. This review deals with the observed fouling phenomena in MD, OD and OMD. It highlights different detected fouling types (organic fouling, inorganic fouling and biofouling), fouling characterization techniques as well as various methods of fouling reduction including pretreatment, membrane modification, membrane cleaning and antiscalants application.

This review gives an overview of the different techniques used to identify, characterize and quantify engineered nanoparticles (ENPs). The state-of-the-art of the field is summarized, the different characterization techniques have been grouped according to the information they can provide. In addition some selected applications are highlighted for each technique. The classification of the techniques has been carried out according to the main physical and chemical properties of the nanoparticles such as morphology, size, polydispersity characteristics, structural information and elemental composition. Microscopy techniques including optical, electron and X-ray microscopy and separation techniques with and without hyphenated detection systems are discussed. For each of these groups, a brief description of the techniques, the specific features and concepts, as well as several examples are described.

“…FFF has found a niche in the analysis of complex and high molecular weight synthetic and natural polymers [9]. The low shear degradation associated with separation in an open channel has enabled the analysis of polymers as large as 10 9 Da and studies that span a wide size and molecular weight range.…”
