    Abstract: 過去數十年來,電子工業已經成為台灣與日本兩國經濟快速成長的重要產業,而半導體工業則扮演其中的關鍵角色。以晶圓的化學-機械研磨(chemical mechanical polishing)程序為例,就需要使用極大量的超純水,所以會造成大量廢水的排放。若能夠使用精密的薄膜過濾程序將廢水中的奈米粒子有效地分離,則將可以達到水資源的回收再利用。此外,軟膠體粒子(例如水膠、蛋白質、乳膠、細胞、微生物及鬆散的絮狀物等)之固-液分離已經成為生物、食品及醫藥技術與廢水處理等眾多工業程序所不可或缺,尤其在台灣與日本變得愈來愈重要,因為這些國家皆缺乏自然資源,而且皆需仰賴工業以生產高附加價值的產品。 目前亞洲的固-液分離領域之卓越研究重心即存在於台灣與日本,經過二十多年的努力,已建立了居於世界領先地位的固-液分離理論與技術,而且這兩個國家的學者們開始研究軟膠體的固-液分離技術的時間比其他任何國家都還要早,目前已經發表了一些重要的成果。所以,台灣與日本基於此既有的優勢,在此研究領域的持續發展、共同合作是極為重要且必須的。故這個合作研究計畫的目的就是闡明在薄膜過濾中奈米與軟膠體粒子的分離及結垢特性,並藉以研發高效能的精密薄膜過濾技術。薄膜結垢會導致濾速嚴重的衰減,故其機制也將由探討濾餅成長與膜孔阻塞之動態行為來釐清。基於這些基礎知識的研發,各種針對奈米與軟膠體粒子的高性能薄膜過濾技術,例如掃流過濾、動態過濾與複合型式的過濾等,將在本計畫中被研發與設計。 本計劃擬由台灣淡江大學化材系之「精密分離研究群」與日本名古屋大學化工系之「精密分離講座」合作,進行為期一年之共同研發。台灣之主要研究人員包含淡江大學化材系的黃國楨教授與鄭東文教授,日本名古屋大學則包含化工系「精密分離講座」的講座教授Eiji Iritani及助理教授Nobuyuki Katagiri。本計劃之研究子題可分為以下六項: 1. 奈米軟膠體粒子之薄膜濾餅過濾的基礎研究 (在日本名古屋大學進行)。 2. 研發高效能之薄膜掃流過濾技術 (在淡江大學進行---主持人黃國楨教授)。 3. 闡明薄膜過濾中奈米軟膠體粒子之結垢機制 (由台灣與日本同時進行)。 4. 研發奈米軟膠體粒子之複合薄膜過濾程序 (在日本名古屋大學進行)。 5. 研發新穎之動態薄膜過濾系統 (在淡江大學進行---主持人鄭東文教授) 6. 研發高效能之奈米軟膠體粒子的薄膜過濾系統 (由台灣與日本同時進行)。 Electronics industry has been a fast-growing sector of economy in Japan and Taiwan over the past few decades. Especially, semiconductor industry holds a critically important position in electronics industry. As represented by the chemical mechanical polishing (CMP) process which is conducted to planarize the wafer, a large amount of ultrapure is used, and as a result a large amount of wastewater is discharged. We believe that the wastewater reclamation will be achieved by separating nano particles contained in wastewater, using the sophisticated membrane filtration technology. On the other hand, solid-liquid separation of the soft particles such as hydrogels, proteins, emulsions, cells, microbes and loosely formed flocs is applied to the fields of bio-, food and medical technologies and water treatment, and is becoming more and more important especially in Japan and Taiwan, which are scarce of natural resources and therefore depend on such industries manufacturing value-added products as food processing, medicine manufacture and development of new materials. The main purpose of this joint research is to clarify the separation properties of nano and soft particles in membrane filtration, and to afford the optimum design and processing of sophisticated membrane filtration. The mechanisms of the membrane fouling were clarified by investigating the dynamic behaviors of the cake formation and the pore clogging, resulting in the dramatic flux decline. On the basis of these fundamental knowledge, a variety of high performance membrane filtration techniques were developed by conducting cross-flow filtration, dynamic filtration, and hybrid filtration.
