“…Montmorillonite was represented by sharp peaks at 20.79°, 23.12°, and 33.22°, while a distinct peak of quartz was detected at 26.49°. This pattern corresponds with prior research studies by Satyannarayana et al [18].…”

“…Additionally, it suggests the presence of a stoichiometric silicon dioxide structure. Moreover, the peak at 794 cm -1 stated the existence of the Si-O bond, thereby confirming the presence of quartz [18]. Consequently, it can be inferred that the FTIR outcomes aligned with the results acquired through the XRD result interpretation.…”

“…Additionally, a reduction in surface area confirmed enzyme immobilization and the filling of the cracks by the enzymes. The crucial properties needed to create a high-quality membrane include a flawless surface without any significant pores, defects, or cracks, but with porosity, robust mechanical strength, and corrosion resistance [18]. A faultless disc ceramic membrane was successfully produced by implementing the refined fabrication process.…”

Low‐cost ceramic microfiltration membranes were explored for immobilizing lipases. Expensive commercial ceramics (e.g., alumina, zirconia) have advantages like chemical robustness, but high sintering temperatures limit their usability. To overcome this, researchers used Fuller's earth clay with rice husk ash to create cost‐effective membranes. However, fewer reactive sites on ceramic surfaces hinder enzyme immobilization. To address this, 3‐aminopropyltriethoxysilane and glutaraldehyde activated the membrane for covalent lipase binding. The immobilized membrane retained activity for over five 1‐h reaction cycles with a minimal performance decline of around 60 %. After five cycles, it retained over 40 % of the initial activity. These results show promise for using low‐cost ceramic membranes in various industries, such as in food, beverages, pharmaceuticals, and chemical production.

“…Low-cost raw materials, including dolomite, rice husk ash, fly ash, kaolin, sepiolite clay, apatite, Algerian clay, Moroccan clay, Cameroonian clay, bentonite clay, Fuller's earth clay, Tunisian clay, and waste bone powder are used to reduce the cost of membranes [22][23][24][25]. Using materials like fly ash and waste bone minimizes the solid wastes in the environment [26][27][28][29]. Many researchers used this low-cost technology and prepared membranes specified for a particular industrial application [14,15,20].…”

“…The mechanical strength ranges from 10 MPa to 69 MPa [56,57]. Further, the extrusion technique was also utilized to fabricate a tubular ceramic membrane from bentonite clay that exhibited 37 % porosity with an average pore size of 0.11 mm and showed good mechanical strength of 18 MPa [27]. It can be concluded that clays as raw materials can be used to synthesize MF or UF support or active layers, which are applied to remove suspended particles, dyes, and oil droplets [53,58,59].…”

Membrane separation processes are becoming a significant part of fruit juice processing industries because of their excellent selectivity, absence of thermal and chemical treatments, and energy efficiency. Specifically, the applicability of ceramic membranes in citrus fruit juice clarification is more promising as they are highly stable in a corrosive environment and have a longer lifetime. However, ceramic membranes are costlier than polymeric membranes due to the high cost of raw materials. Therefore, numerous alternative low‐cost precursors for making the ceramic membrane are being utilized. Accordingly, the current review is focused on the different low‐cost raw materials and various fabrication methods to synthesize different ceramic membranes. Further, the ceramic membrane's application in fruit juice clarification is intensely discussed. In any membrane separation process, fouling is an unavoidable constraint. In the current review, various mechanisms involved in fouling are emphasized in detail. In addition, a variety of techniques to reduce fouling are extensively deliberated. Furthermore, ceramic membranes' challenges and future perspectives for further development are also systematically highlighted.

The water shortage crisis and industrial progress have led to the upgrading of wastewater treatment processes. Hence, the remediation of wastewater and removal of contaminants is becoming a significant issue for environmentalists. However, the design and optimization of affordable treatment procedures with better removal performance is still a challenge for the researchers. Although porous ceramics with excellent porosity are appropriate for separation and adsorption of wastewater and water pollutants owing to their enlarge surface area, fluid permeability and capacity of water absorption, its production is an expensive process. Therefore, using low‐cost and benign compounds for the production of ceramics is an important issue. This review provides the application of the ceramic manufactured from natural sources and biomass for wastewater treatment and removal of pollutants. The effect of these compounds on the structure and efficiency of ceramics is discussed and suggestions are offered for further research.This article is protected by copyright. All rights reserved.
