Comparative Investigation of the Effect of Pre and Post -Enzymatic Refining on OCC Pulp Properties

In this research, the effect of different steps of enzymatic treatment including enzymatic pre-refining and post-refining by Endoglucanase was investigated on the quality of OCC pulp. Three pulps including a: control sample (without enzyme addition), b: enzymatic pre-refining (enzyme treatment + ref...
