Green ceramic hollow fiber membranes with superhydrophobic and superoleophilic surfaces (ss-CHFM/WSBA) were successfully fabricated via facile sol–gel process using tetraethoxysilane (TEOS) and methyltriethoxysilane (MTES) as precursors. In this work, silica solution was prepared using the modified Stöber method. This process was followed by dipping the pristine membranes into the sol–gel solution at various grafting times (0–90 min), grafting cycles (0–4 cycles), and calcination temperatures (400–600 °C). The wettability, surface morphology, and chemical composition of the pristine and ss-CHFM/WSBA membranes were investigated. The results showed that increasing the grafting time has increased the wettability of ss-CHFM/WSBA with high contact angle of up to 163.9°. Similarly, increasing grafting cycle has enhanced the hydrophobicity of ss-CHFM/WSBA due to the formation of hierarchical structure of grafting cycle which were more than one. The optimum calcination temperature for ss-CHFM/WSBA was identified. It was found that increasing the calcination temperature has degraded the sol template on the surface of ss-CHFM/WSBA, hence decreasing the wettability. The preliminary performance tests showed that ss-CHFM/WSBA grafted at 60 min, 3 cycles, and calcined at 400 °C showed excellent oil/water separation efficiency of 99.9% and oil flux of 137.2 L/m2h.

The practical use of ceramic membrane has been limited by their fabrication technique and brittleness. Nowadays, phase inversion and sintering technique for ceramic membrane fabrication has been received widely attention. However, the unavoidable unstable structure for fabrication of flat-sheet ceramic membrane using this technique is still becoming an issue. To overcome this problem, in this paper, flat-sheet ceramic membrane have been developed via modified phase inversion and sintering technique using kaolin as main ceramic material, polyethersulfone (PESf) as the polymeric binder and N-methylpyyrolidone (NMP) as the solvent, respectively. The modified phase inversion has been done by adding drying process before the immersion into solvent. The influence of kaolin composition (60-80g) and drying temperature (room temperature and 3oC) have been investigated extensively to optimize the preparation. The results showed that the ceramic membrane prepared at 80g kaolin composition with drying temperature of 3oC displayed the highest bending strength of 53.1g with excellent BSA and humic acid rejection. Therefore, this study proved that the problem of unstable fabrication technique for flat-sheet ceramic membrane can be solved via modified phase inversion through the influence of high composition and low drying temperature.

Industrial textile wastewater is toxic due to the presence of recalcitrant color pigments and poisonous heavy metals. In this study, the hydroxyapatite (HAp)-based bio-ceramic hollow fiber membranes (h-bio-CHFM) were developed via the combined phase inversion and sintering technique. It was found that the properties of the developed h-bio-CHFMs were greatly affected by the HAp content of the ceramic suspension, and sintering temperature. The h-bio-CHFM with the sintering temperature of 1200 °C exhibited the long rod-shaped HAp particles and the smallest pore size (0.013 μm). High removals of color (99.9%), COD (80.1%), turbidity (99.4%) and conductivity (30.1%) were achieved using the h-bio-CHFM sintered at 1200 °C with stable high flux of 88.3 L/m2h. Remarkably, the h-bio-CHFM sintered in the temperature range of 1000–1200 °C also demonstrated excellent adsorption ability towards heavy metals with 100% removals. The results of this study show the potential of the h-bio-CHFM for the efficient industrial textile wastewater treatment applications.

2023-01-01 , Hubadillah S.K. , Mohd Riduan Jamalludin , Othman M.H.D. , Adam M.R.

This paper describes for the first time the synthesis of hydroxyapatite based on bio-ceramic hollow fiber membrane originating from Tilapia fish bones (bio-CHFM/HApT). Prior to the fabrication process, Tilapia fish bones were converted into hydroxyapatite powder by simple calcination method. A well-known method of membrane fabrication; a combination of phase inversion and sintering technique has been used. The study revealed that an exceptional asymmetric structure comprised of desired finger-like and sponge-like structure was induced by the bio-CHFM/HApT. Interestingly, bio-CHFM/HApT sintered at 1100 °C can induced hybrid adsorption/separation for As(III) removal at separation efficiency up to 99.9% and high flux of ∼250 kg/m2h. Additionally, the equilibrium adsorption capacities were obtained within 40 min of contact time. The kinetic information of the removal of As(III) bio-CHFM/HApT is the most suitable for pseudo-first order.

This work intends the characterization of the natural zeolite clinoptilolite and its capability in removing the ammonia in wastewater. The natural zeolite clinoptilolite was characterized using transmittance electron microscopy (TEM), X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, X-ray fluorescence (XRF) and zeta potential prior to the adsorption process. The results showed that the natural zeolite clinoptilolite possessed the lamellar and needle-like structure thus giving the highest surface area for effective adsorption. The main constituent of the element consisted of natural zeolite clinoptilolite is known to have a high affinity towards ammonia. Additionally, the zeta potential analysis has shown that natural zeolite clinoptilolite is negatively charged in all media pH with the highest negative potential of −30 mV recorded at pH 7 thus, contributing to the highly effective electrostatic interaction with the contaminants’ cations. Consequently, the excellent performance in removing ammonia of up to 82.97 % has revealed that the natural zeolite clinoptilolite has a great potential to be developed as a synergized adsorptive ceramic membrane that is combining the adsorption and the filtration of water simultaneously.

Great progress in the development of low-cost ceramic membranes from alternative materials have been achieved recently towards various application especially water and wastewater treatment. However, their significance has not been fully recognized and understood especially in term of their microstructural analysis such as formation of grain growth and microcracks. This review paper summarizes fabrication method, alternative materials, microstructure, wettability, mechanical properties and application of low-cost ceramic membrane. The fabrication method including slip casting, tape casting, extrusion, pressing method and phase inversion technique are described. Alternative materials used in low-cost ceramic membrane fabrication are discussed and categorized into clays, agricultural waste, industrial waste and animal bone waste. The mechanisms of morphology formation, microstructure and wettability properties are analysed. Modification strategies for the surface of low-cost ceramic membrane are discussed, and classified into modification for separation application, modification for photocatalytic application and modification for membrane distillation and membrane contactor system. Modification improves the membrane structure by changing the pore size, porosity and wettability properties of low-cost ceramic membranes. Mechanical properties of low-cost ceramic membranes are also discussed in detail towards several mechanism, like grain growth phenomenon and formation of microcracks which also considered as membrane defects. Grain growth phenomenon can be divided into normal and abnormal grain growth. Meanwhile, formation of microcracks could be occurred in single-phase polycrystalline ceramics that have anisotropic grains or biphasic polycrystalline grains. The application of low-cost ceramic membrane in seawater desalination, oily wastewater treatment, heavy metal adsorption, textile separation and photocatalytic application are reviewed. Finally, some possible opportunities and challenges for further development of low-cost ceramic membrane are pointed out.

2023-01-01 , Adam M.R. , Hubadillah S.K. , Abd Aziz M.H. , Mohd Riduan Jamalludin

Owing to its toxic and cancer-causing consequences on living organisms, water pollution has garnered worldwide attention. As a result of the severe global drinking water shortages caused by the presence of several contaminants in water sources, a variety of treatment methods have been developed. Among accessible removal methods, adsorptive removal by adsorbents including metal–organic frameworks (MOF), metal oxide, carbon-based substances, and zeolite has garnered a great deal of interest because of their abundance of functional groups, relatively large surface area, great chemical and thermal resistance, and excellent adsorption efficiency. Due to their outstanding efficacy and proficiency in the water treatment process, adsorptive membranes are regarded as one of the most advantageous and promising solutions for wastewater reuse technologies. The combination of adsorption and membrane filtration processes, which are characterized by rapid adsorption–desorption volumes, relatively low diffusion impedance, and high flow rates, has garnered considerable interest in recent years. In this study, a bibliometric analysis was undertaken to utilize the Scopus database to find and appreciate the global current status of research on the adsorptive membranes process based on four principal analyses: growth patterns, keyword co-occurrence, topic area, and most cited references. Using the VOSviewer program, a total of 276 Scopus article records published between 1973 and 2021 were extracted and used as input for bibliometric analysis. Since 2016, there have been a large number of articles on adsorptive membranes, and by 2020 there will have been around 40 publications. On the basis of keywords, the principal topics of study in adsorptive membranes may be divided into three clusters: adsorption, membrane studies, and adsorption performance. These bibliometric data provide researchers and business professionals interested in the technology of adsorptive membranes with helpful resources and information on the current research directions of adsorptive membranes.

Zeolite A was successfully synthesized using Perak kaolin which acts as the main source of silica and alumina. The process of beneficiation was conducted on raw kaolin to remove the impurities that existed in natural kaolin and also to increase the physical and chemical characteristic of kaolin. The kaolin was continued to be heated in the furnace with the temperature of 6000C for 4 h which described as a metakaolinization process that transformed it into the amorphous stage. The raw kaolin was characterized by XRD, FESEM, FTIR, PSA, TGA, while metakaolin by XRD, FESEM and FTIR. The mixture of zeolite A was achieved by adding the metakaolin into sodium hydroxide (NaOH) solution without adding other sources of silica and alumina. The solution mixture was stirred for 24 h before undergoing the process of hydrothermal synthesis. Two optimum conditions were studied for Zeolite A synthesizing, which were different molarity of sodium hydroxide and crystallizations time during the hydrothermal process. The successful synthesis of Zeolite A was then characterized by XRD, FESEM, FTIR, PSA, and BET surface area. The BET surface area of Zeolite-A is higher, 5.26 m2/g, compared to natural zeolite, 2.9 m2/g. As demonstrated in this work, Perak kaolin which was successfully synthesized into Zeolite-A with 2 M NaOH and 12-h crystallization time, gave a higher crystallinity percentage, 72.97%. The results obtained revealed that formation The of zeolite A has been highly affected by the NaOH molarity and crystallization time used in the combination of reactions.
