This work aims to optimise the factors that affect the adsorptive removal of ammonia by natural zeolite hollow fibre ceramic membrane (HFCM) in a continuous crossflow system using surface response methodology (RSM). The adsorptive HFCM was first characterised using the scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy prior to the adsorption process. A face-centred central composite design (CCD) was used to statistically visualise the interaction of the factors, namely feed pH, feed concentration, and HFCM dosage, with the response of water permeability and ammonia removal of the HFCM. The optimum conditions for the HFCM performance were feed pH of 7.04, feed concentration of 75.00 mg/L, and HFCM dosage of 0.35 g, with a desirability value of 0.953. The excellent ammonia removal performance (96.5%) reveals that the HFCM possesses great potential to be developed as a synergised system that combines the adsorption and filtration of water.

The adverse effects of ammonia found in wastewater streams lead to the development of advanced water treatment technology, i.e. membrane contactor (MC). In this study, single layer hollow fibre membrane (SLZK) and dual layer hollow fibre membrane (DLZK) were prepared from zirconia and kaolin and modified into hydrophobic membrane through simple grafting process via fluoroalkylsilane (FAS) agent. The properties of membranes such as morphology, surface roughness, mechanical strength, wettability and liquid entry pressure were analysed through scanning electron microscopy (SEM), atomic force microscopy (AFM), 3-point bending strength, contact angle and LEPw setup. Finally, the performance of the membranes was also investigated towards ammonia removal via membrane contactor system. Our findings showed that hydrophobicity properties significantly improved for both SLZK and DLZK membranes after grafting modification process as indicated by the increase of contact angle value from 5° and 1° to 132.7° and ~180.0° respectively. Based on the morphological analysis, the surface of DLZK showed more porous structure as compared to the SLZK. In addition, DLZK also displayed the highest mechanical strength and contact angle reading of 125 MPa and ~180° respectively. This suggests that the DLZK showed an excellent membrane contactor performance with highest value of mass transfer coefficient (3.77 x 10-5 ms-1) and almost complete removal of ammonia removal (91%). Overall, these results implied that dual layer ceramic membrane developed from kaolin and zirconia could provide the basis for the development of alternative ceramic membrane with excellent properties for membrane contactor system.

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.

The characteristics of the solid fuel pellets, such as its strength, durability and density can be used to assess its quality. During the transport and storage, pellets with low strength and durability produces dusts and ultimately resulting in equipment blockage, high pollution emissions, and an increased risk of fire and explosion. Therefore, pellet manufacturing process should be given priority to improve pellet quality. The use of binder in the production of pellets will aid in improving pellet quality. Therefore, this study investigates the influence of different binder percentages on the mechanical properties of K. senegelensis fuel pellets. Durability, unit density, bulk density and diametral compressive strength testing were carried out in compliance with international standards. It was discovered that pellets containing 4% cassava starch binder produces better results, particularly in terms of durability and compressive ldiametral strength.

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.

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.
