To enhance the removal of natural organic matter (NOM) in ceramic (Ce) membrane filtration, an iron-aluminum binary oxide (FAO) was applied to the ceramic membrane surface as the adsorbent cake layer, and it was compared with heated aluminum oxide (HAO) for the evaluation of the control of NOM. Both the HAO and FAO adsorbent cake layers efficiently removed the NOM regardless of NOM's hydrophobic/hydrophilic characteristics, and the dissolved organic carbon (DOC) removal in NOM for FAO was 1–1.12 times greater than that for HAO, which means FAO was more efficient in the removal of DOC in NOM. FAO (0.03 μm), which is smaller in size than HAO (0.4 μm), had greater flux reduction than HAO. The flux reduction increased as the filtration proceeded because most of the organic foulants (colloid/particles and soluble NOM) were captured by the adsorbent cake layer, which caused fouling between the membrane surface and the adsorbent cake layer. However, no chemically irreversible fouling was observed on the Ce membrane at the end of the FAO adsorbent cake layer filtration. This means that a stable adsorbent cake layer by FAO formed on the Ce membrane, and that the reduced pure water flux of the Ce membrane, resulting from the NOM fouling, can easily be recovered through physicochemical cleaning.

为了提高陶瓷（Ce）膜过滤中天然有机物（NOM）的去除效果，将铁铝二元氧化物（FAO）作为吸附剂滤饼层应用于陶瓷膜表面，并将其与加热的氧化铝（ HAO）用于NOM控制的评估。无论NOM的疏水性/亲水性如何，HAO和FAO吸附饼层均有效去除NOM，FAO中NOM中的溶解有机碳（DOC）去除量比HAO高1-1.12倍，这意味着FAO效率更高在NOM中删除DOC。粮农组织（0.03μm）的大小小于HAO（0.4μm），其通量减少量大于HAO。通量的减少随着过滤的进行而增加，因为大多数有机污垢（胶体/颗粒和可溶性NOM）被吸附剂滤饼层捕获，这导致了膜表面和吸附剂滤饼层之间的结垢。但是，在粮农组织吸附剂滤饼层过滤结束时，未在Ce膜上观察到化学上不可逆的结垢。这意味着由FAO在Ce膜上形成稳定的吸附剂滤饼层，并且由于NOM结垢而导致的Ce膜纯净水通量减少，可以通过理化清洗轻松恢复。
