METHOD OF MANUFACTURING FILTER AID

摘要

Disclosed is a cellulose-based filter aid having high performance to remove suspended substances, and a method for producing it. The method for producing a filter aid comprises the steps of: (A) obtaining a pretreated biomass by pulverization treatment and/or thermochemical treatment of a cellulose-containing biomass; (B) treating the pretreated biomass obtained in the Step (A) with cellulase to obtain a cellulase-treated product; and (C) obtaining a solid content of the cellulase-treated product of the Step (B). The cellulose-based filter aid comprises a water-insoluble cellulase-treated product of a cellulose-containing biomass.
