Recently designed, a multiframe flat sheet membrane contactors (MF-FSMC), consisting in ten parallel frames alternating aqueous and organic phase, was successfully used for chromium (VI) removal from aqueous solution. As a result, five chambers contain aqueous phase and the others contain the organic phase. Aliquat-336 was used as a carrier using polypropylene flat sheet membrane for Chromium (VI) removal. The results show that the extraction was more efficient by increasing the inlet chromium concentration and the number of frames but was not affected by the increasing of the thickness of frames (volume of chambers).

To determine the interaction between different parameters, a full factorial design of experiment was used. The results show that the concentration of Aliquat-336 was the most important parameter, decreasing the efficiency of the system when increasing its concentration. Moreover, the temperature and the membrane contact aera have a positive effect on the extraction efficiency. However, no interaction effects were found in the chosen interval. The optimal values of different parameters are 10 % for Aliquat-336 concentration, 59 cm² for the membrane contact area and 40 °C for the temperature.

最近设计的多框架平板膜接触器（MF-FSMC）由十个平行的框架组成，交替地由水相和有机相组成，已成功用于从水溶液中去除铬（VI）。结果，五个腔室包含水相，其他腔室包含有机相。Aliquat-336用作载体，使用聚丙烯平板膜去除铬（VI）。结果表明，通过增加进口铬的浓度和增加框架数，提取更为有效，但不受框架厚度（腔室容积）增加的影响。

为了确定不同参数之间的相互作用，使用了完整的因子设计实验。结果表明，Aliquat-336的浓度是最重要的参数，当增加浓度时会降低系统的效率。此外，温度和膜接触区对萃取效率有积极影响。但是，在选定的时间间隔内未发现任何交互作用。不同参数的最佳值为Aliquat-336浓度为10％，膜接触面积为59 cm ²，温度为40°C。
