A method for controlling zebra mussels in aqueous systems comprising treating aqueous systems which contain zebra mussels or which are prone to zebra mussel infestation with an effective amount of a water-soluble dialkyl diallyl quaternary ammonium polymer (polyquat). A preferred polymer is a poly(quaternary ammonium) compound having the recurring structure [DMDAAX. sup. - ] resulting from the polymerization of monomeric dimethyl diallyl ammonium X. sup. -, wherein X. sup. - is any suitable anion.

A method for controlling zebra mussels in aqueous systems comprising treating aqueous systems which contain zebra mussels or which are prone to zebra mussel infestation with an effective amount of a composition comprising a) a water-soluble dialkyl diallyl quaternary ammonium polymer (polyquat); and b) didecyl dimethyl ammonium halide. A preferred polymer is a poly(quaternary ammonium) compound having the recurring structure [DMDAAX. sup. - ] resulting from the polymerization of monomeric dimethyl diallyl ammonium X. sup. -, wherein X. sup. - is any suitable anion.

In the flocculation and removal of suspended matter from water, combinations of cationic and nonionic water-soluble polymers are found to be more effective than equivalent concentrations of cationics alone, and significantly lower concentrations of the combination are found to be equivalent in effect to higher concentrations of cationic polymers alone.
