METHOD OF TREATMENT OF ACRYLAMIDE AQUEOUS SOLUTION PREPARED BY BIOTECHNOLOGICAL METHOD FROM BIOCATALYST SLIME Russian patent published in 2003 - IPC

Abstract RU 2198927 C2

FIELD: chemical technology. SUBSTANCE: method involves addition of cation-active flocculant solution and finely-dispersed mineral addition from dioxide in the amount 0.0002-0.02 wt.-% and 0.05-1.0 wt.-%, respectively, to acrylamide aqueous solution obtained with bacterial biocatalyst in concentration of acrylamide from 5 to 50% that is carried out before filtration at stirring. This allows to remove biocatalyst slime with the enhanced efficiency that results to increase of filtration rate and to alleviate precipitate removal from filter. EFFECT: improved method of treatment, simplified process. 1 tbl, 8 ex
