【讲座信息】

   人口和工业的快速增长严重推动了全球用水需求。海水淡化和水的再利用是满足高水需求和维持繁荣的重要解决方案。然而，目前用于水再利用和海水淡化的主要膜具有诸如结垢，高能耗和对氯的弱耐受性的缺点。迫切需要突破膜材料和系统设计以提高其性能。本演示文稿不仅旨在简要介绍膜技术和材料的最新进展，还重点介绍了水再利用和海水淡化领域新一代膜的研发方向。我们将从薄膜复合材料（TFC）和薄膜纳米复合材料（TFN）膜开始，因为它们不仅是过去半个世纪反渗透（RO）海水淡化的主要膜，也是正向渗透（FO）和纳米过滤（NF）在过去二十年中。由于TFC膜的制造工艺已经很好地建立，因此可以容易地扩大TFN膜材料上的任何突破以用于商业化。然后我们将讨论其他新兴的膜技术，如用于水再利用和海水淡化的膜蒸馏（MD），以实现零液体排放脱盐（ZLDD）的目标。

内容简介（英文）

"The rapid growth of population and industries has driven the global water demand harshly. Seawater desalination and water reuse are essential solutions to meet the high water demand and sustain our prosperity. However, the current dominant membranes for water reuse and seawater desalination have drawbacks such as fouling, high energy consumption and weak resistance to chlorine. Breakthroughs on membrane materials and system design are urgently needed to increase their performance. This presentation not only aims to briefly introduce the recent progresses on membrane science and materials but also highlight the emerging R&D directions for next generation membranes in the fields of water reuse and seawater desalination. We will start from thin-film composite (TFC) and thin-film nanocomposite (TFN) membranes because they are not only the dominant membranes for reverse osmosis (RO) seawater desalination in the last half century but also for forward osmosis (FO) and nano-filtration (NF) in the last two decades. Since the fabrication process for TFC membranes is well established, any breakthrough on TFN membrane materials can be scaled up easily for commercialization. Then we will discuss other emerging membrane technologies such as membrane distillation (MD) for water reuse and seawater desalination to achieve the goal of zero liquid discharge desalination (ZLDD).  "
