本报告介绍了一种将粉末活性炭（PAC）用于超滤循环的原始处理方法。这种组合使得在一个物理设备内完成两个基本单元操作（澄清和吸附）成为可能，这两个操作通常在两个单独的反应器中连续进行。这种组合应用于两种不同类型的水:含有浊度、有机碳和微污染物的地表水；含有引起味道和气味的物质的深井水。 结果表明，无论是在低（ppm）剂量或正常至高（15ppm）剂量下使用，添加PAC都不会影响过滤速率。此外，研究表明，使用PAC可以去除可靠溶解的有机碳和微污染物。研究还表明，尽管接触时间很短，但吸附率接近100%。这归因于水力条件，有利于有机物向吸附剂的传质。

This report presents an original treatment integrating the use of powdered activated carbon (PAC) in an ultrafiltration loop. This combination makes it possible to accomplish within one single physical apparatus two essential unit operations (clarification and adsorption) usually performed successively in two separate reactors. This combination was applied to two different types of water: a surface water containing turbidity, organic carbon, and micropollutants; a deep well water containing taste and odor causing substances. It is shown that the addition of PAC does not impair the filtration rate, whether it is applied at low (ppm) or normal to high (15 ppm) dosages. Furthermore, it is shown that the use of PAC makes it possible to remove reliably dissolved organic carbon and micropollutants. It is also shown that despite a quite short contact time, the adsorption yield is close to 100%. This is attributes to the hydraulic regime, favoring the mass transfer of the organics towards the adsorbent.
