Study of membrane fouling by BSA using pulsed injection technique

This paper discusses a new technique for studying membrane fouling. The foulant is introduced into the membrane module in the form of a pulse and the transmembrane pressure (TMP)–time profiles obtained during constant permeate flux ultrafiltration (UF) are used to quantify concentration polarization and fouling. The fouling of a 25kDa polysulfone membrane by BSA is studied at different constant permeate flux values at conditions where there is …
