Abstract
  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 + refining) ...  Read More

Abstract
  The present study analyzed the effect of different enzymatic treatment times using endoglucanase and refining levels to improve the properties of OCC pulp. The OCC pulps were treated by endoglucanase enzyme at a constant dosage of 1u (on o.d. pulp) at different reaction times (0.5, 1, 1.5 and 2 hours) ...  Read More
