The permeation rates of the rice straw liquid hydrolysate were
similar (16.6–29.0 kg m–2 h–1) for all three membranes (Table 3).
The liquid hydrolysate was concentrated about twofold (2.07,2.05, and 2.06 times for NTR-729HF, NTR-7250, and ESNA3, respectively)
with glucose and xylose concentrations of 1.99 and 2.25
times, 1.71 and 1.83 times, and 1.85 and 2.09 times after passage
through NTR-729HF, NTR-7250, and ESNA3 membranes, respectively.
These results showed that these three membranes can
separate water and concentrate sugars from liquid hydrolysate.
