Results from an on-going research programme are presented which illustrate the factors affecting
the fouling of polymeric microfiltration membranes by colloidal and fine particulate matter.
Experimental data obtained from a computer controlled crossflow apparatus show how flux decline
is influenced by a matrix of particle, suspension, membrane and process parameters. Relevant
variables such as feed concentration, crossflow velocity, filtration pressure and suspension pH are
delineated and separated to highlight the salient features of the crossflow process. The results
obtained to date from the project explain some of the anomalies which have been reported in the
published literature and indicate ways in which process design can be improved.
