Wastewater reuse and desalination have been recognized as viable methods for securing sustainable water supplies. Forward osmosis (FO), with its inherent advantages over energy-intensive reverse osmosis (RO), has gained significant attention as a promising technology for both wastewater reuse and desalination applications. However, a key challenge for FO is the regeneration of the draw solution, which is a high-energy step needed to recover the water and reuse the draw solute. One potential solution to address both the water and energy challenges is the integration of solar energy into FO systems. This can be achieved by using solar energy to power the draw solution regeneration process, thereby reducing dependence on conventional energy. This review provides a brief overview of FO emerging applications across various fields, with a particular focus on the integration of solar energy for draw solution regeneration, including the use of photovoltaic (PV) systems, solar thermal systems, photovoltaic thermal (PVT) systems and solar-driven interfacial evaporation. The energy demands of draw solute recovery and the role of solar energy in FO are elucidated, along with the challenges and perspectives of scaling solar-driven FO systems. While it remains uncertain whether solar-powered FO can achieve the cost advantages of large-scale operations comparable to RO, its potential integration with other membrane and non-membrane processes presents significant opportunities for further techno-economic studies to evaluate its viability alongside conventional RO processes. Finally, target factors and translation into real-world applications are presented.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 3","pages":"Article 116332"},"PeriodicalIF":7.4,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143747551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The massive and unregulated use of diphenyl ether herbicides has led to their accumulation in soil and water bodies, altering the structure of soil microbial communities and causing huge economic losses by causing damage to sensitive crops in subsequent crops. Meanwhile, it will also accumulate in the food chain, inducing potential hazards to non-target organisms such as aquatic animals and human beings. Therefore, the importance of developing green removal strategies for diphenyl ether herbicides in polluted environments is increasing. Currently, microbial degradation technology has a broad application prospect due to its simple operation, safety and less likely to cause secondary pollution. A variety of <em>Pseudomonas</em> and <em>Bacillus</em> species have been found to efficiently degrade diphenyl ether herbicides, but fewer studies have been conducted on fungi and actinomycetes. Based on this, this paper summarizes the characteristics of the diphenyl ether herbicide family, the mechanism of toxicity.

This review comprehensively investigated the generation processes and control measures for GHGs emission in CCI process. According to the different ways of primary conversion processes, CCI divided into three major processes, i.e., coal coking, coal gasification, and coal liquefaction. The coking industry accounts for 60 %–70 % of carbon dioxide (CO<sub>2</sub>) emissions in the CCI, with fuel combustion accounting for 80 %–90 % of its largest contribution.

In addition, the adjustment of the H/C in the syngas produced CO<sub>2</sub> in water gas shift unit, and the incomplete combustion of fuel leads to CO<sub>2</sub> emissions from air separation and coal gasification units.
