【講座信息】

   人口和工業(yè)的快速增長嚴重推動了全球用水需求,。海水淡化和水的再利用是滿足高水需求和維持繁榮的重要解決方案,。然而，目前用于水再利用和海水淡化的主要膜具有諸如結垢,，高能耗和對氯的弱耐受性的缺點,。迫切需要突破膜材料和系統(tǒng)設計以提高其性能。本演示文稿不僅旨在簡要介紹膜技術和材料的最新進展,，還重點介紹了水再利用和海水淡化領域新一代膜的研發(fā)方向,。我們將從薄膜復合材料（TFC）和薄膜納米復合材料（TFN）膜開始,，因為它們不僅是過去半個世紀反滲透（RO）海水淡化的主要膜，也是正向滲透（FO）和納米過濾（NF）在過去二十年中,。由于TFC膜的制造工藝已經(jīng)很好地建立,，因此可以容易地擴大TFN膜材料上的任何突破以用于商業(yè)化。然后我們將討論其他新興的膜技術,，如用于水再利用和海水淡化的膜蒸餾（MD）,，以實現(xiàn)零液體排放脫鹽（ZLDD）的目標。

內(nèi)容簡介（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).  "
