三维表示支持数学概念，即随着跨膜压力的增加和水回收率的降低，渗透浓度将降低；然而，已确定回收率对渗透液浓度的影响程度与跨膜压差的影响程度相同。与所有其他运行参数相比，渗透液浓度对水传质系数的变化更为敏感。这意味着，在膜过程的未来研究中，考虑到K可以保持，最值得关注的操作参数是水的传质系数。

Three-dimensional representations supported the mathematical concept that as transmembranic pressure increased and water recovery decreased, the permeate concentration would decrease; however, it was determined that recovery does not affect the permeate concentration in the same degree as the transmembranic pressure differential. The permeate concentration has been shown to be more sensitive to changes in the water mass transfer coefficient relative to all other operational parameters evaluated. This signifies that the operational parameter that warrants the most attention in terms of future research in membrane processes is the water mass transfer coefficient, given that K, can be maintained.
