摘要:	本研究針對操作參數對平板沉浸式薄膜過濾BSA溶液之影響進行探討，討論的變數包括有曝氣量、抽濾壓力、薄膜特性及模組傾斜角度等。本研究得出: (1)過濾BSA溶液，使用親水性薄膜有較高的濾速值。(2)在過濾BSA系統中，相同曝氣量下，薄膜傾斜160度時之濾速大於傾斜90度時之濾速。(3)薄膜的阻塞方式不是依據標準阻塞、完全阻塞、中間阻塞及濾餅過濾等逐漸發生，而是同時發生。(4)進料濃度的改變，不會改變阻塞方式。(5)從阻塞模式分析發現，曝氣量能有效降低濾餅過濾阻塞阻力。 In this study, the influences of operating parameters on flat-membrane submerged filtrations of BSA solution were investigated. The operating parameters included aeration rate, suction pressure, membrane characteristics and module inclination angle. The experimental results were summarized as follows: (1) During the operation of single-liquid phase filtration of BSA solution, hydrophilic membrane has a higher flux than hydrophobic one; (2) The flux of 1600 membrane inclination is higher than that of 900 inclination at the same aeration rate; (3) The way of blocking of the membrane does not happen step by step from standard blocking, complete blocking, intermediate blocking to cake filtration, but occurs coincidently; (4) The change of feed concentrate does not influence the way of blocking; (5) Aeration can effectively reduce the filtration resistance of cake filtration according to the blocking mechanism analysis.
