CROSS-FLOW MICROFILTRATION PROCESS

摘要

A method of establishing an essentially steady state cross-flow filtration flow in a cross-flow membrane filtration module by starting at a low transmembrane pressure (TMP) and steady state operation and then increasing the TMP by an iterative procedure until the performance starts to become unstable and then backing down the TMP slightly until the performance restabilizes. One preferred embodiment employs a filtration module that describes a flow length such that the permeate pressure is equal to the concentrate pressure.
