“…27 Ceramic-based membranes are rapidly attaining prominence in the medical field as a solution to these problems due to their thermal efficiency, chemical stability, mechanical strength, higher separation efficiency, long lifetime and antifouling properties. [28][29][30][31] To the best of our knowledge, a tubular membrane made of ceramic material has never been used for hemofiltration. Thus, the generation of a ceramic tubular membrane for application to hemofiltration may be considered novel.…”

Background There has been a surge of interest in the preparation of membranes for clinical applications, chiefly for hemodialysis and hemofiltration. Despite numerous benefits, the exploitation of polymeric materials for dialysis membrane preparation remains unsatisfactory due to lack of proper physicochemical properties and biocompatibility. Therefore, this work focuses on the preparation of a ceramic membrane in a tubular configuration using an extrusion method and a clay material mixture. The biocompatibility of the membrane as well as its structural properties were studied. Results The porosity, permeability and pore size of the membrane were 39 ± 0.88%, 203 ± 0.51 L m−2 h−1 bar−1 and 304 ± 1.20 nm, respectively. The corrosion tolerance of the membrane was found to be better in acidic, alkaline and chlorine solutions. The protein adsorption, hemolysis and platelet adhesion were 2.1 ± 0.03 μg cm−2, 1.02 ± 0.01% and 6856 ± 84 platelets mm−2, respectively. The membrane demonstrated a prolonged blood coagulation time (PT = 18 ± 0.33 s and APTT = 70 ± 0.57 s), a 171 ± 0.57 s whole blood clotting time and complement activation of 805 ± 1.3 mg L−1 for C3 and 247.3 ± 0.98 mg L−1 for C4. During synthetic blood filtration, the membrane had sieving coefficients of 0.98 ± 0.005, 0.97 ± 0.008 and 0.93 ± 0.005 for creatinine, urea and phosphate, respectively. Finally, the membrane revealed a protein rejection of about 56 ± 0.57%. Conclusions The overall findings indicated that the prepared tubular membrane with excellent biocompatibility and uremic toxin removal can be used for hemofiltration application as an alternative to hemodialysis. © 2022 Society of Chemical Industry (SCI).

“…To selectively absorb only oil from an oil–water mixture, the focus has mostly been on fabricating materials that are superhydrophobic (with a water contact angle of >150° on the absorbent) and superoleophilic (with an oil contact angle of <15° on the absorbent) or superhydrophobic and oleophilic (with an oil contact angle of <90° on the absorbent). − Many researchers have utilized hydrophobic polymers, such as polystyrene and polydimethylsiloxane, for the needed wettability. − Other studies have incorporated fluoro materials to increase hydrophobicity. , In a recent review, Sam and co-workers summarized several methods for surface engineering sponges, including cellulose sponges, to improve their surface hydrophobicity, in particular, to change the sponges’ surface wettability to superhydrophobic and superoleophilic by using hydrophobic agents, such as organosilanes, , either alone , or in combination with other nanomaterials. , While superhydrophobic sponges are common in most studies, Minju et al have reported the use of hydrophobic alkylsilane modified sponges that had water contact angles between 100° and 125° and oil contact angles of ∼0° to selectively and completely absorb various oils from seawater. Hydrophobic foams of polyurethane modified with organosilane, having water contact angles of 105–110°, also resulted in a high oil collection capability in the study by Zimmermann et al These latter studies clearly illustrated that hydrophobic, not necessary superhydrophobic, sponges were sufficient for selective removal of oil from water.…”

Designing absorbents having specific wettability toward both oil and water is the key for selective and effective oil absorption and removal. For this purpose, establishing explicit correlations between surface tension of oils and surface wettability of absorbent is crucial. In this study, we modified common low-cost cellulose sponges with various organosilanes to achieve a range of hydrophobicity/oleophilicity and then assessed their oil uptake selectivity and capability. Oil uptake was followed as mass uptake versus time and analyzed based on the spreading coefficient (S) of a liquid over a solid surface. The results showed that sponges needed to be hydrophobic, not necessarily superhydrophobic, to selectively absorb oil from an oil/water mixture. To achieve a fast uptake and a high uptake capacity, an S ≥ 0 was necessary, that is, when the sponges were completely wet by the oil. Increasing the porosity of cellulose sponge led to a slight increase in oil uptake capacity, and a greater increase resulted when bacterial cellulose sponges that consisted of smaller and more uniform voids/pores were used. S ≥ 0 could be used as a criterion for evaluating effective and rapid oil uptake for porous absorbents, especially for those containing heterogeneous pore structures, such as common cellulose sponges.

“…The turbidity was also found to be reduced around 92%. Another study used a low cost superhydrophobic-superoleophilic kaolin-based hollow fiber ceramic membrane for the recovery of oil from synthetic produced water [30].

“…The concept of sol gel dip-coating bentonite membranes using nanoparticles can be the pioneer of study regarding to the surface modification of bentonite membranes for the treatment of PW since there was not reported before. Thus, this study will be more focused on the effect of grafting time (30,60, and 90 min) of TiO 2 nanoparticles on bentonite membranes to find the optimum grafting time via the characterization and the performance of the coated membrane toward oil rejection and pure water flux, using synthetic PW.…”

The main problem usually faced by commercial ceramic membranes in the treatment of produced water (PW) is low water flux even though ceramic membrane was well-known with their excellent mechanical, thermal, and chemical properties. In the process of minimizing the problem faced by commercial ceramic membranes, titanium dioxide (TiO2) nanocomposites, which synthesized via a sol-gel method, were deposited on the active layer of the hydrolysed bentonite membrane. This paper studied the influence of grafting time of TiO2 nanocomposite on the properties and performance of the coated bentonite membranes. Several characterizations, which are Fourier transform infrared (FTIR), scanning electron microscopy (SEM), energy-dispersive X-ray Spectroscopy (EDX), contact angle, porosity, and average pore size, were applied to both pristine and coated bentonite membranes to compare the properties of the membranes. The deposition of TiO2 nanoparticles on the surface of the coated bentonite membranes was successfully confirmed by the characterization results. The pure water flux performance showed an increment from 262.29 L h−1 m−² bar−1 (pristine bentonite membrane) to 337.05 L h−1 m−² bar−1 (Ti-Ben 30) and 438.33 L h−1 m−² bar−1 (Ti-Ben 60) as the grafting time increase but when the grafting time reached 90 min (Ti-Ben 90), the pure water flux was decreased to 214.22 L h−1 m−² bar−1 which is lower than the pristine membrane. The oil rejection performance also revealed an increase in the oil rejection performance from 95 to 99%. These findings can be a good example to further studies and exploit the advantages of modified ceramic membranes in PW treatment.
