ABSTRACT:
Methods for inhibiting the attachment of microbes to surfaces in aqueous systems are disclosed. Copolymers of a tannin and a cationic monomer are added to aqueous systems, such as papermaking and cooling water systems, to inhibit microbial attachment to surfaces which cause slime formation problems.
