    If recovery is the primary concern, selection of a tighter membrane (6x) will yield maximum recovery (with a slower flow rate). These values should be used as a general guide, as solute retention and selectivity can vary depending on many factors, such as transmembrane pressure, molecular shape or structure, solute concentration, presence of other solutes, and ionic conditions.
