Abstract

• A new semi-portable set-up has been successfully developed to perform MFI-UF tests at constant flux filtration. The set-up has been used for on-site testing and for testing in laboratory. • Two membrane materials (PES and RC) and various MWCOs (100, 50, 30 and 10 kDa) were investigated for MFI-UF tests. • MFI-UF measured with membranes with smaller pores gives higher values. Measurements at lower flux result in lower values. • The particulate fouling potential of Mediterranean and North Sea water was measured with MFI-UF (with 100 kDa membranes). The measured values were 2 to 8 times higher for the North Sea samples than for the Mediterranean samples. • At a SWRO facility, ultrafiltration pretreatment reduced the MFI-UF - measured with membranes with pores 100, 50 and 10 kDa - by 94 %, 93 % and 87 %, respectively.
