Innovative solar steam generation breakthrough

Description

Solar steam generation (SSG) is recognized as a sustainable technology for seawater desalination, but its practical applications have been hampered by salt fouling, which compromises the evaporation performance and lifespan of evaporators. Addressing this issue, a research team from City University of Hong Kong (CityUHK) has developed a groundbreaking solution - a hierarchical salt-rejection (HSR) strategy that prevents salt precipitation during long-term evaporation, even in high-salinity brine. This innovative research is a significant step forward in advancing various applications such as resource recovery and offshore farming, thereby paving the way for a more sustainable future.
