Recovery and separation of cellulose from sawdust wood hydrolysates using membrane creator: effect of transmembrane pressure (TMP) and cross flow velocity (CFV)

Cellulose is among the most important natural resources that contain polysaccharides. In this study, the effect of transmembrane pressure (TMP) and cross-flow velocity (CFV) on permeate flux during the recovery and separation of cellulose from sawdust wood hydrolysates by using membrane reactor was...
