“…The reuse of water is especially crucial for water-scarce regions and various reuse applications are conceivable to minimize water stress. For example, Czuba et al (2021) suggest, depending on the secondary effluent treatment, the reuse of treated wastewater for groundwater recharge, agricultural irrigation, as a cooling medium, as potable water or as industrial water.…”

Dissemination of multiresistant bacteria and high concentrations of micropollutants by hospitals and other medical facilities can be significantly reduced by a wide variety of on-site treatment approaches. Membrane filtration technologies, ranging from microfiltration to reverse osmosis, have been adapted in many studies and offer multiple purposes in advanced wastewater treatment configurations. While the direct rejection of pharmaceutical compounds and pathogens can only be achieved with nanofiltration and reverse osmosis processes, porous membranes are known for their pathogen removal capabilities and can be used in combination with other advanced treatment approaches, such as oxidation and adsorption processes. This review was conducted to systematically assess studies with membrane filtration technologies that are used as either stand-alone or hybrid systems for the treatment of hospital wastewater. In this review, four different databases were screened with a pre-set of search strings to thoroughly investigate the application of membrane filtration technology in hospital wastewater treatment. Hybrid systems that combine multiple treatment technologies seem to be the most promising way of consistently removing micropollutants and pathogens from hospital wastewater, but additional economic assessments are needed for an extensive evaluation.

“…Membrane technologies have archived the maturity to accelerate the transition toward the circular blue economy, offering a wide portfolio of energy-saving and sustainable processes able to produce freshwater from effluents [252]. Seawater desalination, considered the most reliable solution to face the freshwater scarcity problem (being the sea an unlimited and renewable water body), is today dominated by SWRO.…”

Water and energy are two strategic drivers of sustainable development, intimately interlaced and vital for a secure future of humanity. Given that water resources are limited, whereas global population and energy demand are exponentially growing, the competitive balance between these resources, referred to as the water-energy nexus – is receiving renewed focus.The desalination industry alleviates water stress by producing freshwater from saline sources, such as seawater, brackish or groundwater. Since the last decade, the market has been dominated by membrane desalination technology, offering significative advantages over thermal processes, such as lower energy demand, easy process control and scale-up, modularity for flexible productivity, and feasibility of synergic integration of different membrane operations. The exciting new frontier of sustainable mining of seawater concentrates is accelerating the appearance of a plethora of innovative membrane materials and methods for brine dehydration and selective extraction of trace ions, although under the sword of Damocles represented by cost feasibility for reliable commercial application. On the other hand, among several emerging technologies, reverse electrodialysis (SGP-RED) was already proven capable – at least at the kW scale–of turning the chemical potential difference between river water, brackish water, and seawater into electrical energy. Efforts to develop a next generation of Ion Exchange Membranes exhibiting high perm-selectivity (especially toward monovalent ions) and low electrical resistance, to improve system engineering and to optimize operational conditions, pursue the goal of enhancing the low power density so far achievable (in the order of a few W per m2).This Roadmap takes the form of a series of short contributions written independently by worldwide experts in the topic. Collectively, such contributions provide a comprehensive picture of the current state of the art in membrane science and technology at the water-energy nexus, and how it is expected to develop in the future

“…In industrial production, the application of membrane technology enables factories to recycle water resources and achieve self-sufficiency, reducing their greenhouse gas emissions. − Geglio et al conducted an analysis of the economics of microhousehold circulating water and showed that the use of membrane bioreactors for wastewater treatment and recycled water for irrigation or toilet flushing could save 92 m 3 of water, 26 kWh of energy, and 10.79 kg of carbon dioxide emissions . At present, in addition to being used in urban applications, recycled water treated by RO and combined processes has reached the standard for recycled drinking water. − Figure summarizes several membrane processes and their recycled water utilization pathways. − …”

Membrane technology has become a key common technology to solve major problems in the fields of global water resources, energy, and the environment and is one of the most developed high-tech methods in the 21 st century. However, due to the high cost and low reuse rate of membrane technology, its energy consumption and carbon footprint are still high, which is the main factor limiting its use. Therefore, we need to clarify the method used to calculate greenhouse gas emissions from this technology and put forward effective emission reduction programs. Based on the life cycle assessment method, the accounting boundary of greenhouse gas emissions from membrane technology is defined. According to this boundary, the greenhouse gas emissions in the whole life cycle of membrane technology are divided into direct emissions, indirect emissions, and carbon compensation, and the measured emission factor method is used to calculate the greenhouse gas emissions. Then, we discuss the effective pathways for reducing carbon emissions by this technology: (1) reduce energy consumption by optimizing operating conditions and coupling membrane systems with clean energy; (2) recover and utilize organic matter byproducts and recycled water; and (3) recycle waste membrane components in whole or in part. Studies have found that membrane technology can overcome its current challenges and even achieve net zero emissions under a recycling scheme, but quantitative data are still lacking. Finally, we hope to provide a valuable reference for carbon emission accounting and carbon emission reduction in studies of membrane technology.
