“…Hudaib et al (Hudaib et al, 2019) investigated the separation performance of low-pressure tubular TiO2-CNF membranes operating at 2 bar. The effect of the valences, type of ions, transmembrane pressure (TMP), and the Zeta potential of the membrane on the separation of ions was studied experimentally.…”

“…In other words, negative rejection for a given ion species only occurs when more of that ion is in the smaller permeate volume relative to the much larger feed volume. In the same line, a membrane with negative rejection enhances the transport of that solute or ion across it (Yaroshchuk, 2008;Labban et al, 2017, Hudaib et al, 2019. Chloride R% Sodium R% causing Mg 2+ to pass more freely through the membrane (Pontalier et al, 1997).…”

<p>The application of ceramic Nanofiltration (NF) membrane in brackish water treatment is increasing due to strict water quality standards. Ceramic NF is a widely used membrane process and has replaced reverse osmosis (RO) membranes in many applications due to lower energy consumption and higher flux rates. This work aims to study the separation performance of tubular ceramic TiO2 Nanofiltration membrane at low-pressure (2 bar) for single and tertiary salt mixture separation. The results showed that the rejection of ions is ordered as follows: R (Cl1-) ion size > R calcium (Ca2+) ion size > R sodium (Na1+) ion size > R magnesium (Mg2+) ion size. Moreover, the highest Cl1- rejection was about 46%, the highest Ca2+ and Mg2+ rejection was about 44%, and the highest Na1+ rejection was about 37%. The pure water flux through the investigated ceramic NF membrane for distilled water was calculated to be 5.29 x 10-7 m3 s-1 m-2 bar-1, and this flux was dropped down for the salt mixture feed to 2.56 x 10-7 m3 s-1 m-2 bar-1 due to the presence of salt particles in the feed.</p>

“…For dye and salt separation, Fang et al employed a peristaltic pump with a low-pressure feed of 0.2 MPa for nanofiltration employing the PES-iron ion complex [26]. For water treatment, Hudaib et al employed a ceramic TiO 2 nanofiltration membrane with a feed pressure of 0.2 MPa [27]. For wastewater treatment, Amin et al utilized 0.27 MPa on PES/GO nanoribbons and PES/GO nanosheets [28].…”

Removal of Scale-Forming Ions and Oil Traces from Oil Field Produced Water Using Graphene Oxide/Polyethersulfone and TiO2 Nanoribbons/Polyethersulfone Nanofiltration Membranes

Treatment of produced water in oil fields has become a tough challenge for oil producers. Nanofiltration, a promising method for water treatment, has been proposed as a solution. The phase inversion technique was used for the synthesis of nanofiltration membranes of polyethersulfone embedded with graphene oxide nanoparticles and polyethersulfone embedded with titanium nanoribbons. As a realistic situation, water samples taken from the oil field were filtered using synthetic membranes at an operating pressure of 0.3 MPa. Physiochemical properties such as water flux, membrane morphology, flux recovery ratio, pore size and hydrophilicity were investigated. Additionally, filtration efficiency for removal of constituent ions, oil traces in water removal, and fouling tendency were evaluated. The constituent ions of produced water act as the scaling agent which threatens the blocking of the reservoir bores of the disposal wells. Adding graphene oxide (GO) and titanium nanoribbons (TNR) to polyethersulfone (PES) enhanced filtration efficiency, water flux, and anti-fouling properties while also boosting hydrophilicity and porosity. The PES-0.7GO membrane has the best filtering performance, followed by the PES-0.7TNR and pure-PES membranes, with chloride salt rejection rates of 81%, 78%, and 35%; oil rejection rates of 88%, 85%, and 71%; and water fluxes of 85, 82, and 42.5 kg/m2 h, respectively. Because of its higher hydrophilicity and physicochemical qualities, the PES-0.7GO membrane outperformed the PES-0.7TNR membrane. Nanofiltration membranes embedded with nanomaterial described in this work revealed encouraging long-term performance for oil-in-water trace separation and scaling agent removal.
