The effective membrane area in this module was 32 cm2
. A pressure of 0.5 and 1.5 MPa was
applied to the glucose and diluted sugar beet molasses solution,
respectively. In addition, pressure of 2.0, 1.5, and 1.5 MPa were applied
to dilute acid-pretreated rice straw liquid hydrolysate
(140 mL) passing through the NTR-729HF, NTR-7250, and ESNA3
membranes, respectively. The volume of the liquid hydrolysate
feed solution decreased within about one second. The permeate
weights using the NTR-729HF, NTR-7250, and ESNA3 membranes
were 2.26, 2.24, and 2.25 kg m–2, respectively.
