The present study is part of a research program that is aimed at developing a procedure that can be used to optimize the permeate yield for a full-scale membrane system based on simple bench-scale tests. The present study investigates the impact of the operating permeate flux on the evolution of the resistance offered by a submerged membrane to the permeating liquid (i.e. increase in trans-membrane pressure). The increase in the trans-membrane pressure observed during the present study is governed by the operating permeate flux, the hydrodynamic conditions and the system configuration. The increase in the trans-membrane pressure can be modeled using a simple exponential relationship that is a function of the operating permeate flux, the pseudo-steady-state permeate flux, which is governed by the system hydrodynamics and configuration, and the volume of permeate filtered. Although additional work is required to develop a comprehensive procedure that can be used to optimize the permeate yield for a membrane system, results to date suggest that it is possible to accurately predict the evolution of the permeate flux in a full-scale system using data collected using simple bench-scale tests.
