“…Researchers mainly focus on synthesizing inorganic materials (Cho et al 2011b;Drobek et al 2012) or polymeric materials for the application of pervaporation desalination. The reported data demonstrate that both inorganic and polymeric PV membranes have high salt rejections but the water fluxes are relatively low (0.2-22.87 L/(m 2 h)) when separating a 1 wt% NaCl solution at 63°C (Wang et al 2016a;Xie et al 2011;Zwijnenberg et al 2005). Poly(vinyl alcohol) (PVA), with a super hydrophilicity and good film-forming ability, is an excellent polymeric material for PV.…”

“…Therefore, a PV membrane has a dense selective layer which can mitigate the fouling problem encountered by a typical MD process where the pores of the MD membrane are easily fouled during the separation process. In the last decade, researchers start to study the feasibility of PV membranes for salty water desalination (Chaudhri et al 2015;Cho et al 2011b;Drobek et al 2012;Liang et al 2014Liang et al , 2015Wang et al 2016b;Xie et al 2011;Zwijnenberg et al 2005).…”

The pyromellitic dianhydride (PMDA) crosslinked poly(vinyl alcohol) (PVA) was coated on top of the PAN ultrafiltration membrane to form a PVA/PAN composite PV membranes for wastewater desalination. The composite membranes have high application value in industrial wastewater treatment. By varying the membrane fabrication parameters including the weight percent (wt%) of the PMDA, the crosslink temperature and duration, membrane with the best desalination performance was obtained. The composite membrane with a 2-lm-thick PVA selective layer containing 20 wt% of PMDA and being crosslinked at 100°C for 2 h showed the highest NaCl rejection of 99.98% with a water flux of 32.26 L/(m 2 h) at 70°C using the 35,000 ppm NaCl aqueous solution as feed. FTIR spectroscopy, wide-angle X-ray diffraction, thermogravimetric analysis and scanning electron microscope have been used to characterize the structures and properties of both the crosslinked PVA dense films and PVA/PAN composite membranes. The effects of the concentrations of PMDA, the crosslinking time and temperature to the membrane water contact angle, swelling degree, salt rejection and water flux were systematically studied.

“…The pervaporation of an aqueous salt solution can be regarded as separation of a pseudo-liquid mixture containing free water molecules and bulkier hydrated ions formed in solution upon dissociation of the salt in water [1]. Previous studies have demonstrated the possibility of applying pervaporation to produce distilled water from aqueous salt solutions [1,3]. However, the water flux reported so far is generally quite low, at <6 L/m 2 ·hr [4,5].…”

Highly dispersed homogeneous hybrid polymer-inorganic membranes based on poly(vinyl alcohol) (PVA), maleic acid (MA) and inorganic silica were synthesized via a sol-gel method. Tetraethoxy-silane (TEOS) was used as the silica precursor with MA as an additional crosslinking agent. A range of techniques such as FTIR, SEM, TGA, XRD and DSC were used to characterise the nanostructure and properties of hybrid membranes. Results revealed silica nanoparticles (<10 nm) were well dispersed in the polymer matrix with chemical bonding between the organic and inorganic phases. Thermal properties of the hybrid membranes were significantly enhanced when compared with pure PVA membranes, and swelling of PVA based hybrid membranes was greatly suppressed.The chemically crosslinked PVA with maleic acid and silica resulted in the formation of new hybrid membranes with improved pervaporation properties for desalination application. The pervaporation separation performance of aqueous salt solution was found to be directly related to the diffusion coefficient of water through hybrid PVA/MA/silica membranes. Introduction of MA and silica at given amounts into the polymer chain increased the amorphous region of the membrane and favoured the diffusion of water molecules through the membrane. A water flux of 6.93 kg/m 2 ·hr with salt rejection of >99.5% was achieved at a 6 Torr vacuum and 22°C.

“…Depending on the exact characteristic of the particular source of produced water different technology is appropriate. Hydrocyclones, centrifuges, membrane filtration, and activated carbon or filters are all techniques that have been used to perform produced water treatment [21][22][23]. A primary concern when treating produced water is the removal of the dissolved and suspended oil and grease.…”
