METHOD OF MAKING AUXILIARY FILTRATION MATERIAL Russian patent published in 2016 - IPC B01J20/24 B01D39/04 B01D37/02 

FIELD: technological processes.

SUBSTANCE: invention relates to filtration. Disclosed is a method of making auxiliary filtration material, which involves steps A, B and C. Step (A) involves obtaining pretreated biomass by grinding processing and/or thermochemical treatment of cellulose-containing biomass, thermal treatment is processed selected from a group consisting of acid treatment, hydrothermal treatment, treatment with steam explosion, alkaline treatment and ammonium treatment. Step (B) includes processing biomass, obtained at step (A), with cellulase to produce treated cellulase product. step (C) involves obtaining solid content of said processed cellulase product obtained at step (B).

EFFECT: obtained auxiliary filtration material has high efficiency of separation of suspended substances.
