FIELD: textile; paper.
SUBSTANCE: method (in version) concerns paper manufacturing and can be applied in pulp and paper industry. Method involves: (i) supply of water suspension containing pulp fiber, (ii) adding to suspension after the last point of severe shear force exposure of: (a) first anion component of anion organic polymer soluble in water; (b) second anion component of anion organic polymer dispersed in water or branched organic polymer; and (c) third anion component of anion material containing silicon; and (iii) dehydration of obtained suspension to produce paper. Also invention concerns composition (in version) including first, second and third anion components, and application of the composition as flocculation agent in production of pulp mass and paper for water treatment.
EFFECT: improved water drainage and retaining during paper manufacturing out of any type of pulp suspensions, accelerated operation of paper-making machine, reduced polymer dosage applied.
