ANODICALLY POLARIZED SURFACE FOR BIOFOULING AND SCALE CONTROL

摘要

ANODICALLY POLARIZED SURFACE FOR BIOFOULlNG AND SCALE CONTROL Biofouling and scale control in conductive aqueous systems is effected on metal, preferably valve metal such as titanium, surfaces on which such fouling normally occurs by applying thereto a stable electrocatalytic coating, anodically polarizing said valve metal coating such that only oxygen isevolved at the surface thereof, preferably at a rate at least about 4.66 millimoles per square meter per hour without evolution of any chlorine.
