Methods for treating regulated waters with low levels of oxidizing halogens and hydrogen peroxide are disclosed, wherein the halogen-containing compound is provided with an erosion control agent such as glycoluril, and the hydrogen peroxide is provided with a hydrogen peroxide stabilizer such as a polyquaternary ammonium compound. Additional stabilizers to chelate metals and increase the half life of peroxide in aqueous solutions may also be added.

Methods for inhibiting microbial growth in aqueous systems by the use of synergistic mixtures comprising poly(hexamethylammonium) chloride and at least one compound selected from the group consisting of poly (iminoimidocarbonyliminoimidocarbonyliminohexamethylene hydrochloride ('PHMB') , dodecylguanidine hydrochloride ('DGH') and poly[oxyethylene (dimethylimino) ethylene-(dimethylimino) ethylene dichloride] ('PDED'). Antimicrobial compositions comprising the synergistic mixture and a carrier are also disclosed.
