“…Fouling and scaling are highly dependent on the parameters of the feed water and foulants, as well as the membrane properties and operational parameters. Among various methods of MD membrane preparation methods, phase inversion and electrospinning are useful on a lab scale but hollow-fiber membranes are more useful in an industrial or pilot scale [191].…”

Membrane distillation (MD), a temperature‐driven membrane separation process, is used for various applications due to its less complicated design. MD operations encounter major issues such as permeate flux decrease, membrane fouling, and wetting. A lot of research has been conducted in the past years on the modification of MD membranes by incorporating nanomaterials to overcome these obstacles and considerably increase their performance. Nanomaterials incorporated into the membranes improve the water permeability, mechanical strength, and fouling. The incorporation of next‐generation nanomaterials like metal oxide nanoparticles, carbon‐based nanomaterials, graphene‐based membranes, quantum dots, and metal‐organic frameworks in the MD membranes is investigated. Essential membrane properties for MD operations are comprehensively studied, including higher liquid entry pressure, permeability, porosity, hydrophobicity, thermal stability, mean pore size, and low fouling rate. Significant advances in the application of nanomaterials to the modification of MD membranes as well as other membrane fabrication techniques adopted for the incorporation of nanoparticles like surface grafting, interfacial polymerization, plasma polymerization, and dip coating are reviewed. Important future aspects are discussed.

Membrane Distillation (MD) is a membrane-based, temperature-driven water reclamation process. While research emphasis has been largely on membrane design, upscaling of MD has prompted advancements in energy-efficient module design and configurations. Apart from the four conventional configurations, researchers have come up with novel MD membrane module designs and configurations to improve thermal efficiency. While membrane design has been the focus of many studies, development of appropriate system configurations for optimal energy efficiency for each application has received considerable attention, and is a critical aspect in advancing MD configurations. This review assesses advancements in modified and novel MD configurations design with emphasis on the effects of upscaling and pilot scale studies. Improved MD configurations discussed in this review are the material gap MD, conductive gap MD, permeate gap MD, vacuum-enhanced AGMD/DCMD, submerged MD, flashed-feed MD, dead-end MD, and vacuum-enhanced multi-effect MD. All of these modified MD configurations are designed either to reduce the heat loss by mitigating the temperature polarization or to improve the mass transfer and permeate flux. Vacuum-enhanced MD processes and MD process with non-contact feed solution show promise at the lab-scale and must be further investigated. Hollow fiber membrane-based pilot scale modules have not yet been sufficiently explored. In addition, comparison of various configurations is prevented by a lack of standardized testing conditions. We also reflect on recent pilot scale studies, ongoing hurdles in commercialization, and niche applications of the MD process.

“…The researchers found that DCMD was able to eliminate Ca þ , Sr þ2 and Co þ2 from wastewater and the DCMD flux decreased linearly by 60% due to increasing NaNO 3 concatenation, and found that DCMD is a promising technology in the separation of radioactive wastewater. Furthermore, Jia et al (2021) designed a VMD pilot-scale desalination plant for decontaminating radioactive wastewater. The researchers studied the impact of operating conditions on VMD performance.…”

The importance of membrane technology development in our daily life cannot be overemphasized. Over the past decades, membrane technology has become very popular in providing potable water for mankind. However, old technologies (such as reverse osmosis and ultrafiltration) which are highly energy intensive are still very common in water treatment industries. In this review work, the capability of low energy consumption membrane distillation (MD) technology was reviewed with emphasis on material development and energy requirement. We began by reviewing the history of MD process, configurations, module types, membrane materials, material fabrication methods, material properties, material modification techniques, application, and energy requirement. Factors which influence the performance of MD–both design and operating conditions–were then extensively discussed. Furthermore, we report desalination and wastewater treatment as the hottest areas of application where MD has gained significant interest. Membrane hydrophobicity and fouling resistance as pivotal areas where improvement in MD performance is being sought after are identified. Finally, we discussed various industries where MD is presently being applied. We conclude by highlighting the energy requirements of MD and identified solar energy as a renewable energy resource which could meet the energy requirement of MD technology. This review paper is believed to foster the interest and provide insights on material development for membrane distillation application.
