摘要：
An all-in-one treatment composition for a water cooling tower includes a water soluble aromatic azole corrosion inhibitor such as benzotriazole, an organophosphorous antiscalant and a polymeric quaternary ammonium compound. The polymeric quaternary ammonium compound has the following general formula: ##STR1## The composition is suitable for use at low level continuous applications rates. The polymeric quaternary ammonium compound is also suitable for use at low concentration as a continuous biocide/biostat. This compound does not suffer from the acclimatization typically encountered when one biocide is used on a continuous low level basis.
