Membrane filtration assembly and method of controlling trans-membrane pressure

摘要

The present invention relates to a membrane filtration assembly (1) and a method of controlling trans-membrane pressure (TMP) by means of a permeate side co-crrent cross-flow (16,16'). Said membrane filtration assembly comprising a trans-membrane pressure control system including pressure sensors (32,33,34,35) and flow control means (20, 22) for controlling the trans-membrane pressure (TMP) profile versus the lenght of the module.
