“…However, these materials can be costly, are less effective for ammonia adsorption, and possess inconsistency potentially due to different batches of the waste [17]. For example, bauxite contains a high amount of alumina; thus, it requires high sintering temperature to be produced as a ceramic membrane [18]. Meanwhile, the usage of the fly ash may lead to the production of porous materials that contain various phases including mullite, anorthite, and cordierite [19].…”

Natural zeolite is widely used in removing ammonia via adsorption process because of its superior ion-exchange properties. Ceramic particle size affects the adsorptivity of particles toward ammonia. In this study, hollow fiber ceramic membrane (HFCM) was fabricated from natural zeolite via phase inversion. The effect of natural zeolite particle size toward the properties and performance of HFCM was evaluated. The results show that the HFCM with smaller particle sizes exhibited a more compact morphological structure with better mechanical strength. The adsorption performance of HFCM was significantly improved with smaller particle sizes because of longer residence time, as proven by the lower water permeability. A high adsorption performance of 96.67% was achieved for HFCM with the smallest particle size (36 μm). These findings provide a new perspective on the promising properties of the natural zeolite-derived HFCM for ammonia removal.

“…The technique of liquid separation using inorganic membranes has been one of the most compelling developments in recent decades, as they have the potential for highly selective separations through manipulation of their thermal and chemical properties [1,2]. In particular, sintered inorganic microfiltration (MF) membranes have had ample interest, especially for industrial applications.…”

The development of inorganic membranes has mainly found applicability in liquid separation technologies. However, only a few reports cite the permeation and separation of liquids through inorganic nanofiltration membranes compared with the more popular microfiltration membranes. Herein, we prepared silica membranes using 3,3,3-trifluoropropyltrimethoxysilane (TFPrTMOS) to investigate its liquid permeance performance using four different ion solutions (i.e., NaCl, Na2SO4, MgCl2, and MgSO4). The TFPrTMOS-derived membranes were deposited above a temperature of 175 °C, where the deposition behavior of TFPrTMOS was dependent on the organic functional groups decomposition temperature. The highest membrane rejection was from NaCl at 91.0% when deposited at 200 °C. For anions, the SO42− rejections were the greatest. It was also possible to separate monovalent and divalent anions, as the negatively charged groups on the membrane surfaces retained pore sizes >1.48 nm. Ions were also easily separated by molecular sieving below a pore size of 0.50 nm. For the TFPrTMOS-derived membrane deposited at 175 °C, glucose showed 67% rejection, which was higher than that achieved through the propyltrimethoxysilane membrane. We infer that charge exclusion might be due to the dissociation of hydroxyl groups resulting from decomposition of organic groups. Pore size and organic functional group decomposition were found to be important for ion permeation.

“…The latter allows the membrane to operate under high back pressure [337]. However, the main drawbacks of this technique are the prolonged casting time, the difficulty in controlling the thickness and uniformity of the deposited film, and the mold breakage after few casts which, hence, new molds are required which raise the production cost [338]. Numerous materials such as alumina [285], titania [275], zirconia [339], and perovskite [340] have been utilized in slip casting technique to fabricate MF and UF ceramic membranes.…”

“…This technique is used to prepare thin flat ceramic sheets. It consists of casting tape, casting knife, moving carrier and casting reservoir [338]. The suspension is added to the reservoir and the thickness of the produced film is controlled by the distance between the casting knife and moving carrier.…”
