Pretreatment of Aqueous Pectin Solution by Cross-Flow Microfiltration: Study on Fouling Mechanism

Marcelino L. Gimenes, Vitor R. Silva, Fabiane Hamerski, and Agnes P. Scheer
Abstract—This research was carried out to determine the predominant fouling mechanism during the pretreatment of an aqueous pectin solution by cross-flow microfiltration with membrane with nominal size of 0.44 µm, at different values of transmembrane pressure, temperature, and pectin concentration. To evaluate the predominant resistive mechanism was used series resistance and permeate flux model analysis. The rejection coefficient for pectin varied from 93.4 to 97.9%. The maximum flux observed was 238.69 ± 6.48 kg m-2 h-1 at transmembrane pressure of 0.12 MPa, temperature of 50 °C and initial pectin of 1.0 g kg-1. The dominant restrictive mechanism observed was the cake layer formation, for all assay evaluated.

Index Terms—Pectin, microfiltration, permeate flux, fouling.
