The intermediate pressure range stands for an important condition for ultrafiltration operations where permeate flux falls below that predicted from a linear flux-pressure relationship but does not reach the limiting flux. Optimal performance of ultrafiltration might be achieved on the upper end of the intermediate pressure range because the maximum permeate flux will be obtained at the lowest possible pressure. Unlike in the low pressure range or in the high pressure range, little has been known about the behavior of permeate flux in the intermediate pressure range. A general theory of permeate flux in the intermediate pressure range is developed in this study. The theory includes the linear-increasing and limiting fluxes as two special cases and, therefore, can be used to study the behavior of permeate flux in ultrafiltration in the whole pressure range.

中压范围代表超滤操作的一个重要条件,在此条件下,渗透通量低于由线性通量-压力关系预测的值,但未达到极限通量。在中压范围的上限可能实现超滤的最佳性能,因为能在尽可能低的压力下获得最大渗透通量。与低压范围或高压范围不同,关于中压范围内渗透通量的行为鲜为人知。本研究建立了中压范围内渗透通量的一般理论。该理论将线性增加通量和极限通量作为两种特殊情况包含在内,因此可用于研究整个压力范围内超滤中渗透通量的行为。版权所有1999年学术出版社。
