This paper explores the efficiency and potential of indirect freeze crystallization (IFC) as a valuable resource-recovery technology in wastewater treatment, particularly focusing on acid mine water and hazardous material wastewater-treatment plants. Wastewater treatment poses challenges to recovering valuable resources effectively, enforcing the need for sustainable and resource-efficient technologies like freeze crystallization. Through a thorough examination of IFC principles and mechanisms, this paper aims to highlight its applications, advantages, and limitations. The investigation includes a comprehensive literature review and detailed methodology from one of the IFC pilot plants, as well as a critical analysis of the environmental and economic implications of IFC. By addressing scaling challenges in reverse osmosis and proposing an environmentally friendly brine disposal method through IFC, this paper contributes to reducing the environmental footprint associated with wastewater treatment. Additionally, this paper highlights the importance of extracting valuable resources from highly saline water and emphasises the potential economic and environmental benefits of resource recovery, particularly focusing on the promising technology of IFC.

Membrane separation processes are prevalent in industrial wastewater treatment because they are more effective than conventional methods at addressing global water issues. Consequently, the ideal membranes with high mechanical strength, thermal characteristics, flux, permeability, porosity, and solute removal capacity must be prepared to aid in the separation process for wastewater treatment. Rubber-based membranes have shown the potential for high mechanical properties in water separation processes to date. In addition, the excellent sustainable practice of natural fibers has attracted great attention from industrial players and researchers for the exploitation of polymer composite membranes to improve the balance between the environment and social and economic concerns. The incorporation of natural fiber in thermoplastic elastomer (TPE) as filler and pore former agent enhances the mechanical properties, and high separation efficiency characteristics of membrane composites are discussed. Furthermore, recent advancements in the fabrication technique of porous membranes affected the membrane’s structure, and the performance of wastewater treatment applications is reviewed.

The contamination of water resources is a significant environmental challenge. The creation of innovative technologies to address this challenge is of paramount significance. Nanomaterials within polymeric membranes have surfaced as a hopeful technology within the realm of water purification, offering solutions to crucial issues concerning the elimination of pollutants and pathogens from water supplies. The exceptional properties of nanomaterials within polymeric membranes, including their high surface area, tunable pore sizes, and selective permeability, have enabled significant progress in the effective removal of various contaminants from water. This is due to the integration of nanoscale materials, such as metal nanoparticles, nanofibers, graphene, and graphene oxide, which has further enhanced the membrane performance by introducing enhanced mechanical strength, improved separation efficiency, and increased adsorption capacities. Recent research has focused on tailoring nanomaterials within polymeric membranes to target specific contaminants, such as viruses, bacteria, heavy metals, organic pollutants, and microplastics. Functionalization techniques, such as surface modification and incorporation of specific functional groups, have been employed to enhance the adsorption and separation capabilities of these membranes. Moreover, innovative fabrication methods, including layer-by-layer assembly, electrospinning, and template-assisted techniques, have been explored to achieve precise control over membrane properties and morphology. This review provides an overview of the current status and advancements in the utilization of nanomaterials within polymeric membranes for water purification applications.
