Evaluation of fouling and concentration polarisation during protein ultrafiltration by pulsed sample injection technique

Protein sieving coefficients, concentration polarisation and membrane fouling could be significantly affected by solution pH, ionic strength and permeate flux. The pulsed sample injection technique could be an effective tool for studying the ultrafiltration behavior of proteins under different conditions and for assessing the suitability of membranes.
