Distributed water treatment and desalination (DWTD) systems are critical for the development of a diverse water portfolio of the desired quality and intended use at the target location. Widespread adoption of DWTD has been hampered given the need for round-the-clock monitoring and the lack of local technical expertise for system management. However, self-adaptive operation, real-time remote monitoring, supervisory control, and asset management of DWTD systems are now feasible with the implementation of advanced local system control, cyberinfrastructure that facilitates real-time cloud-based analytics, data management, and artificial intelligence–powered decision support. Such an approach will introduce transformative virtual networks of DWTD systems to provide needed water to locations that are not served by centralized and satellite water treatment and desalination systems.

This perspective attempts to critically assess the latest developments in membrane-based brine concentration (MBC), crystallization (MBCr), and valorization (MBV), which are essential to make desalination more sustainable and to advance a more circular water economy. Herein, we examine membrane distillation, forward osmosis, electrodialysis, osmosis-assisted reverse osmosis, low-salt rejection reverse osmosis, and ultra-high-pressure reverse osmosis as emerging MBC technologies and compare them to each other and state-of-the-art thermal brine concentration. We discuss the implications and operational challenges of these technologies in minimal and zero liquid discharge applications. We further discuss various MBCr and MBV research efforts from the peer-reviewed literature and offer some perspective on what is likely needed to advance MBC, MBCr, and MBV approaches to commercial status.

This work addresses the scale-up challenges of HiGee technology for CO₂ capture by proposing two approaches: (1) constructing a scaled-down prototype with a 5 cm axial-length rotor while maintaining key dimensions the same as the plant-scale unit to gather reliable data for scaling up; and (2) employing ab initio Computational Fluid dynamic (CFD) models that integrate heat, mass transfer, and reaction kinetics, removing the need for empirical correlations. Additionally, a method is suggested to reduce computational resource requirements for CFD calculations.

Efficient capture of volatile organic compounds (VOCs) remains a significant challenge in industrial emissions control. High-gravity (HiGee) technology particularly through the use of rotating packed beds (RPBs) depicts an innovation in this field. RPBs offer a compact, energy-efficient solution for optimizing VOC elimination, addressing both hydrophobic and hydrophilic compounds. As industries face growing regulator pressures and ambitious environmental targets, the adoption of RPBs becomes increasingly attractive for VOC mitigation. This review delves into the mechanism underlying HiGee technology and its role in VOC capture, highlighting its unique ability to fine-tune functionality for specific industrial applications. The discussion encompasses the various applications of HiGee technology in VOC treatment, providing a comprehensive overview of its environmental impacts. The review also identifies future research directions aimed at enhancing the efficiency and expanding the applicability of RPBs in VOC mitigation processes.

Zero-valent iron (ZVI) is a reductive process commonly employed in groundwater remediation; however, in this process, there is a possibility for oxidative pathways to occur, and they might be of importance for pollutant remediation. In the first part of this work, we provide information on key parameters ruling this process. In the second part, we emphasize on the importance of oxidative steps in ZVI treatment, in particular, Fenton-like process driven by hydrogen peroxide generated mainly in aerated media. Also, we describe the use of ZVI as reservoir of iron for neutral Fenton process or for persulfate activation and provide examples of the implementation of sequential reductive and oxidative processes with potential niche applications. Throughout the work, key mechanistic aspects are addressed, and examples of waste valorization to obtain ZVI-based materials and processes are given, also reporting on the role of dissolved organic matter as auxiliary.

Meeting the increased demand for rare earth elements and uranium for clean energy technologies requires additional sources beyond primary mined ore. Secondary sources like phosphogypsum, coal fly ash, used nuclear fuel, and electronic waste are concentrated sources of critical minerals. One strategy for a resilient supply chain is to decentralize sourcing and hydrometallurgical processing of metals. Rotating packed beds (RPBs) for solid-phase extraction and liquid–liquid extraction are gaining momentum for their ability to increase process throughput by 5–10x the state of the art. This review discusses advances in hydrometallurgical RPB processes and opportunities for implementation in distributed metals production.

Polymer membranes are an energy-efficient separation technique useful for liquids, gases, and biologics. Traditional membranes are manufactured using a solvent-based system that is very scalable but relies on the use of large volumes of toxic solvents. An alternative manufacturing route is melt processing, which eliminates organic solvents. Micro- and ultra-filtration applications are well suited for melt-manufactured membranes with strong separation performance demonstrated that is comparable to solvent-based manufacturing techniques. Melt manufacturing of membranes for gas separations remains difficult, however. New routes of membrane design are proposed, allowing for melt manufacturing to create membranes for a more complete spread of applications.

Gravitation dictates the allowable flow phases and the achievable mass transfer rates in classic distillation columns, which are tall for that exact reason. High-gravity (HiGee) devices use a high centrifugal field to increase the interfacial area through high-speed rotating packing, resulting in a large enhancement of gas–liquid mass transfer and thus smaller equipment volumes. HiGee is an effective process intensification approach to enhance both reaction and separation efficiency. Combining reaction and distillation in a HiGee equipment (R-HiGee) is a topic that attracts significant attention. This paper summarises recent developments in HiGee (reactive) distillation technologies, including process synthesis and design, modelling and analysis of rotating packed bed systems, and equipment design. It also highlights future directions for developments in order to facilitate the systematic evaluation and application of high-gravity (reactive) distillation technologies.

Monodispersed nanoparticles are the pivotal in optimizing the performance of nanomaterials and propelling innovation in nanotechnology applications. This paper reviews advancements in the synthesis of monodispersed inorganic nanoparticles, such as metals, metal oxides, and inorganic salts, within liquid systems by high gravity technology. Special focus is given on the critical role of in situ modification in achieving monodispersed and morphologically uniform particles. Leveraging the superior mixing capabilities of high gravity technology and the precise control offered by in situ modification, these nanoparticles demonstrate significant enhancements in their applications within organic systems. Catalytic efficiency is markedly increased, and the properties of composite materials are optimized. This underscores the successful integration of high gravity technology with materials science in propelling the development of practical functional materials. Looking ahead, monodispersed inorganic nanoparticles synthesized and the composites they formed via high gravity technology and in situ modification are poised to usher in a new era in nanotechnology.

Photocatalysis has been widely used to address the environmental issues and energy crises that threaten the future of planet Earth. One of the main drawbacks to developing photocatalysts for practical applications is the electron–hole recombination concept, which seriously hinders the photoreaction rate. To resolve this, heterojunctions with different patterns, including Z and S schemes, showed great potential to enhance photoactivity and thus attracted increasing attention. Herein, we concisely reviewed recent progress in various types of such systems, focusing on the mechanistic understanding of clean energy and environmental applications. The principles of constructions based on optoelectronic properties and semiconducting behavior are comprehensively discussed. The advantages and disadvantages of each system are also considered to make a logical conclusion and inspirational perspectives.
