“…The membranes prepared in the current study showed a comparable performance or better performance in some cases compared to the membranes known in literature. Although, the separation efficiency of the majority of the membranes known in literature is ≈98% but the flux is not as high as shown by the membranes prepared in the current study which is attributed to the salient features of the MIL-125-NH 2 MOF such as high surface area, porosity, and hydrophilic pores [31][32][33][34] .…”

Ceramic membranes offer significant potential for addressing challenging and harsh wastewater streams such as produced water (PW) and surfactant-stabilized oil/water (O/W) emulsions. This study focuses on developing a stable and a uniformly structured active layer solely composed of MIL-125-NH2 MOF on a ceramic Alumina support. A stable covalent bonding approach was employed using interfacial polymerization, with isophthaloyl chloride (IPC) acting as the organic crosslinker during interfacial polymerization reaction. Three distinct MIL-125-NH2 decorated membranes M50, M75, and M100 were prepared by using varying MOF concentrations. Surface wettability analysis of the membranes indicated that the MIL-125-NH2 MOF active layer displayed super-hydrophilic characteristics in the air (water contact angle = 0°) and super-oleophobic characteristics underwater (oil contact angle = 161.5°). In oil separation experiments, all the MIL-125-NH2 deposited membranes displayed >99% oil rejection. Among the fabricated membranes, M50 demonstrated the highest water flux of 2100 Lm−2 h−1 under a transmembrane pressure of 2 bar. The MIL-125-NH2 MOF deposited membranes also showed stable performance under longer-run filtration. This study would be a simple and effective method of decorating MOFs as an active layer on ceramic support for efficient O/W emulsion separation and desalination applications.

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.
