Ultrafiltration requires hydrostatic pressure (driving force) to
filter a solution through a membrane and to separate solutes in
a solution based on the molecular weight cut-off of the semipermeable
membrane. No phase or state change occurs during the
ultrafiltration process and the solutes separate at room temperature,
therefore, requiring less energy for the process (Cheryan,
1998). The objectives of this study were to: (1) evaluate the
effects of molecular weight cut-off and transmembrane pressure of
ultrafiltration membranes on the permeability of the solution
containing SRBF and (2) determine the performance of ultrafiltration
for separating the small molecular weight sugars and minerals
from solution containing SRBF.
