TL;DR: This work studied the concentration of hydrolyzates obtained from dilute acid hydrolysis of rice straw using nanofiltration (NF) in order to minimize the Donnan exclusion effect of the membrane, the Hydrolyzate solution was controlled at low pH value.

TL;DR: In this paper, a Desal-5 DK nanofiltration (NF) membrane was used to separate acetic acid from xylose, using a synthetic acid-xylose solution as the model.

TL;DR: In this article, a method for concentrating sugars and decreasing fermentation inhibitor concentrations simultaneously before fermentation is disclosed, which includes the steps of adjusting the pH value of a hydrozylate containing sugars and fermentation inhibitors, separating solid and liquid in the hydroZylate, for removing large particles in the solution; and applying a semi-permeable membrane, for concentrating the sugars and increasing the total concentration of the fermentation inhibitors in the hyrozylates, so as to obtain a concentrated solution.
