Abstract

Procedimiento para la disminución de la demanda de oxígeno químico en residuos acuosos que contienen componentes aceitosos, glicoles o ceras, que consisten en forma opcional de residuos de fundición, por medio de un procedimiento electrolítico que implica la evolución del cloro anódico en presencia de hierro trivalente. La evolución del cloro se puede llevar a cabo en la superficie de un ánodo que consiste en un componente permanente de un metal de válvula activada en forma catalítica acoplado a un componente sacrificial que contiene hierro.
