摘要

Process for the concentration by ultrafiltration of a viscous, aqueous solution of a water-soluble polysaccharide, optionally in conjunction with a cell-lytic enzymatic treatment. The concentrate thus produced is convenient to transport and easily diluted to provide an aqueous polymer solution suitable for polymer flooding in enhanced oil recovery.
