“…The absorbance of the prepared oily water was measured using UV/vis spectrophotometer (PerkinElmer Lambda 25) at the wavelength taken between 200 and 450 nm as a calibration curve. The absorbance, A (L•mol −1 cm −1 ) was determined using the Beer-Lambert equation as reported by [19]. J i denotes the representation of Jo for the oil and Jw for the water flux (L/h•m 2 ), V is the volume of the water permeated through the membrane (L), A is the surface area of hollow fiber membrane (m 2 ), and ∆t is the total permeation time (h).…”

“…In material selection, ceramic membranes have been taken into consideration for presenting more advantages in terms of excellent solvent resistance, high permeation flux, high oil rejection, long lifetime, high thermal stability, and exhibiting chemical inertness in the area of MF and UF processes [9]. Several articles have reported various strategies of oil and water separation, especially the use of ceramic membranes and inorganic materials, for instance, alumina [10], αAl 2 O 3 [11], kaolin [12], sugarcane bagasse waste [13], NaA zeolite [14], stainless steel [15], Cu mesh film [16], kaolin/fly ash [17], fly ash [18], magnesium bentonite [19], and ball clay [20]. Even though the membrane with MF meets the requirement for oil-water application, it is not desirable and insufficient for oil-water separation because it can easily be fouled and shorten the life span of the membrane, thereby increasing the cost of membrane maintenance and operation [21].…”

This research aimed to investigate the ultrafiltration of water from emulsified oily wastewater through the application of surface-functionalized ceramic membrane to enhance its water permeability based on optimized parameters using a cross-flow filtration system. The interactive effects of feed concentration (10–1000 ppm), pH (4–10), and pressure (0–3 bar) on the water flux and oil rejection were investigated. Central composite design (CCD) from response surface methodology (RSM) was employed for statistical analysis, modeling, and optimization of operating conditions. The analysis of variance (ANOVA) results showed that the oil rejection and water flux models were significant with p-values of 0.0001 and 0.0075, respectively. In addition, good correlation coefficients of 0.997 and 0.863 were obtained for the oil rejection and water flux models, respectively. The optimum conditions for pressure, pH, and feed concentration were found to be 1.5 bar, pH 8.97, and 10 ppm, respectively with water flux and oil rejection maintained at 152 L/m2·h and 98.72%, respectively. Hence, the functionalized ultrafiltration ceramic membrane enables the separation efficiency of the emulsified oil in water to be achieved.

Ceramic membranes offer considerable promise for future industrial applications due to their superior chemical, mechanical, and thermal stabilities, resistance to harsh operating conditions, and long‐term operating processes. However, several bottlenecks still limit their commercial scale‐up in filtration and separation applications, including brittleness, the high costs of conventional ceramic materials, and fouling. Despite several articles in the literature on ceramic membranes, this review focuses on recent progress, technical strategies, and methods to mitigate these limitations that significantly impact their separation and filtration performance. The use of alternative naturally occurring ceramic materials to mitigate the high costs of conventional ceramic materials is discussed, as well as strategies to improve the mechanical strength of brittle ceramic membranes by increasing sintering temperatures and using support materials. Additionally, advanced techniques to mitigate fouling accumulation and wetting in the pores and on the ceramic membrane surface, such as increasing membrane hydrophilicity and surface modification, are addressed. Despite progress in technical solutions for mitigating the bottlenecks of ceramic membranes, these limitations persist. Therefore, the present limitations and future research directions are highlighted.

“…Over the past years, the study of oil-water separation from oil/water mixture has attracted many researchers. This could also be due to possible re-use of water after oil-water separation due to the water scarcity in many arid regions [6]- [11]. Various technologies have been employed to investigate the separation of oil-water emulsions including the traditional methods such as centrifuges, settling tanks, depth filters and agitation of oil that have the potential of removing the oil particles from oily wastewater.…”

“…However, the maximum transmembrane pressure in the system was reported as the pressure that will push oil/water out of the system without properly being filtered [6], [7], [10], [30]. In the integrated membrane system when the transmembrane pressure increases, also the permeate flux increases, but also when the transmembrane pressure increases it has the potential of increasing the membrane resistance due to the proportionality law [6], [28]. The increase in the membrane resistance is an early indicator of the ceramic integrated membrane system fouling, which will eventually cause the pores blockages and decline in the permeate [27], [28], [31].…”

The integrated membrane system is a promising technology for oily wastewater producing industries. The integrted membrane system achieves the high oil/water emulsions separation at the low-cost operation, however, its feed stream performance is hampered by membrane fouling which causes a decine in permeate flux and oil rejection ratio during the separation process. The poorly estimated transmembrane pressure in the integrated membrane feed stream leads to membrane pores blockages. When the transmembrane pressure builds up in the integrated membrane feed stream causes the decline in the oil/water rejection, which leads to poor membrane performance. The engineering equation solver software was used to model the transmembrane pressure for the optimal performance of the the integrated membrane feed stream during oil/water separation. The theoretical results obtained revealed that increasing the transmembrane pressure, will increase the permeate flux in the integrated membrane feed stream which optimizes the membrane performance. The unique methematical relationship was developed between the membrane pores and feed stream for optimal membrane performance during oil/water separation.
