研究了通过预处理合成地表水降低中空纤维超滤膜污染的方法。研究中使用的预处理机制是添加粉末活性氧化铝浆料。除了确定泥浆在减少污垢方面的功效外，研究还试图通过吸附到粉末活性氧化铝表面来确定砷（III）的去除效率。此外，研究的目的是确定系统的适当操作条件。研究中的变量包括:膜分子量截止值（30k道尔顿对100k道尔顿）；进水流速（200毫升/分钟对530毫升/分钟）；地表水pH值（6.00和8.00）；以及地表水中的总悬浮固体浓度（15 mg/L与100 mg/L）。在整个研究过程中，使用了A/G Technology Corporation中空纤维超滤筒和掺有250 ug/L As（III）的合成地表水。 包括19个参考文献、图表。

The reduction of fouling of a hollow fiber ultrafiltration (UF) membrane via pretreatmentof a synthetic surface water was investigated. The pretreatment mechanism used in the study was the addition of a powdered activated alumina slurry. In addition to determining the efficacy of the slurry in the reduction of fouling, the investigation endeavored to determine the removal efficiency of arsenic in the form of As(III) through sorption onto the surface of the powdered activated alumina. Furthermore, it was an objective of the study to determine the appropriate operating conditions for the system. Variables in the investigation were: membrane molecular weight cut-off (30k daltons versus 100k daltons); influent flow rate (200 mL/min versus 530 mL/min); surface water pH (6.00 and 8.00); and, the total suspended solids concentration in the surface water (15 mg/L versus 100 mg/L). A/G Technology Corporation hollow fiber UF cartridges and a synthetic surface water spiked with 250 ug/L As(III) were used throughout the study. Includes 19 references, figures.
