Abstract
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 is evolved at the surface thereof, preferably at a rate at least about 4.66 millimoles per square meter per hour without evolution of any chlorine.
