    摘要: 本研究主要探討混合微粒子懸浮液之掃流薄膜過濾特性,以0.15和0.8μm之聚甲基丙烯酸甲酯(PMMA)粒子混合溶液進行過濾操作。探討懸浮液成分、液體速度、氣體速度、薄膜方位和操作壓力等濾速之影響,以尋求提升掃流薄膜過濾之效能。除此之外,研究中還進行濾餅之粒徑分佈分析,以瞭解操作條件對濾餅組成之影響。實驗結果顯示:(1)多相流動能有效的提升過濾效能。(3)薄膜傾斜角度為180乾氶A掃流速度對濾速提升之效果明顯。(4)比較不同成分懸浮液之濾速,因粒徑較大之粒子較容易被掃流流體帶走,故懸浮液成分中小粒徑粒子含量越高則濾速越低
    The experiments for cross-flow membrane filtration of mixed particulate suspensions were carried out using mixtures of 0.15 and 0.8μm PMMA particles that were retained by the filter membrane. The effects of operating conditions, such as the composition of suspension, the liquid velocity, the gas velocity, inclination angle and filtration pressure on the permeate flux were discussed in order to searching for the efficiency enhancement in cross-flow membrane filtration. In addition, the particle size distribution of cake was analyzed in order to analyze the effect of various operating conditions on cake composition. The experimental results were summarized as follows: (1) The multiphase flow can obviously enhance the filtration flux. (3) At 180.degree. inclination, the cross-flow velocity could enhance the permeate flux effectively. (4) The more were the small size particles in the suspension, the lower in permeate flux was found.
