    Abstract: 本研究音在討論操作條件對沉浸式薄膜過港之粒
    子附著的影響。以孔洞大小為0.1 μm 之薄膜,過濾平均
    粒徑為7μm 之聚甲基丙希酸甲酯(PMMA)粒子,探討不
    終過濾差提高了近5 倍,而濾餅量則增加約7 倍。當
    粒徑在l~m 以下時,粒子的附著會受到粒子間作用力
    粒子不易附著,使其附著機率下降,且當粒徑越大,此現象就越為顯著。The effects of operated conditions, such as
    flux, filtration time, particle size, aeration
    , air bubble size on the deposition properties, cake
    es, and the performance in submerged membrane
    'on are studied. A particulate sample with a wide size
    'on range is used in experiments. The properties of
    deposition are analyzed based on force analysis
    hydrodynamics. The results show that the interparticle
    force plays a major role in particle . deposition for
    submicron particles. Increasing filtration flux leads to a
    large normal drag force exerted on depositing particles; as
    a result, to increase particle deposition probability. An
    increase in aeration intensity or reduction of bubble size
    may decrease deposition probability for micron particles.
    Furthermore, the estimated cake properties, such as mass,
    porosity and average specific filtration resistance of cake
    are compared with available experimental data .
