Abstract
Page Content
In this study, the impact of membrane properties on membrane fouling and
permeate water quality was investigated. Short- and long-term
laboratory scale experiments using four commercially available hollow
fiber UF membranes were performed to study the impact of membrane
properties on reversible and irreversible fouling. No significant
differences in terms of permeate quality (i.e. biopolymer rejection)
were observed over the four tested membranes. It was found that membrane
characteristics including pore size, pore distribution and especially
materials had a strong impact on the filtration performances in terms of
both reversible and irreversible fouling. The short-term filtration
tests showed that due to its specific hydrodynamic condition only the
inside-out mode UF membrane was subjected to irreversible fouling. These
data demonstrate the importance of membrane selection with appropriate
operating conditions for optimum performances. The added value of
membrane characterization to lab-scale filtration tests for membrane
performance was discussed.
