Graphene helps seawater desalination achieve a major breakthrough, and the market space is expected to be further opened
[Securities Times] according to media reports, recently, the team of academician Ma Jun from the school of environment of Harbin University of technology and the team of Professor Lai Zhiping from King Abdullah University of science and technology jointly tackled key problems and made a major breakthrough in the research field of membrane water treatment technology. Its results were recently published in the international journal advanced materials, In this study, ultra-high throughput porous graphene membrane was designed and synthesized, and efficient and sustainable seawater desalination was realized by using low-quality heat source.
Membrane distillation (MD) uses heat to drive water vapor through the membrane to obtain high-quality clean water. It is not only a seawater desalination technology with great application prospects, but also a key core technology in many zero emission processes. However, the low flux of MD membrane is the main bottleneck restricting the wide application of this technology. The graphene membrane obtained by the scientific research team of Harbin Institute of technology provides a very short and fast transmission path for water vapor, which is one order of magnitude higher than the MD membrane flux reported so far, and the desalination rate is more than 99.8%. It shows great application potential and advantages in seawater desalination.
Comments: there is a vast market space for seawater desalination. The action plan for the utilization and development of seawater desalination (2021-2025) issued by the national development and Reform Commission last year clearly stipulates that by 2025, the total scale of seawater desalination in China will reach more than 2.9 million tons / day, and the new scale of seawater desalination will be more than 1.25 million tons / day. The new low-energy sustainable solution for seawater desalination has achieved a major breakthrough. It is hoped to open the application prospect and space of graphene materials, and the industrial chain companies hope to be concerned.
