Abstract

Un método para tratar sistemas de agua para inhibir la corrosión en acero no galvanizado y otros componentes metálicos en el sistema de agua, que comprende: agregar un polímero a base de aminoácidos o su sal soluble en agua, al agua en el sistema de agua; agregar ácido hidroxifosfonoacético o su sal soluble en agua, al agua en el sistema de agua; agregar un segundo ácido fosfónico o su sal soluble en agua, al agua en el sistema de agua, donde la etapa de agregar proporciona una concentración activa de 3 ppm – 50 ppm del polímero a base de aminoácido o su sal soluble en agua, una concentración activa de 3 ppm – 50 ppm del ácido hidroxifosfonoacético o su sal soluble en agua, y una concentración activa de 2 ppm – 20 ppm del segundo ácido fosfónico o su sal soluble en agua para inhibir la corrosión; y donde no se añaden zinc o molibdeno al agua en el sistema de agua.
