Abstract

The target of this research was to monitor the influence of carbohydrate hydrolysis on dewatering and critical end product characteristics in semi pilot trials using a special unique semi pilot machine at VTT Jyväskylä. The surface chemistry of SC -grade thermo-mechanical pulp (TMP) was modified by commercial endoglucanase rich enzyme. According to results, at least 0.5 - 1.0 % of TMP dry weight had to be hydrolysed in order to increase significantly drainage in former section. Depending on the extent of enzymatic treatment paper properties, such as bulk, porosity, smoothness and strength where influenced by the extent of enzymatic actions. Overall, results indicates that enhanced drainage of TMP could be achieved without deterioration in retention and formation values by controlled enzymatic treatment.
