Application Summary AI generated

This standard specifies the most probable number (MPN) method for detecting and enumerating sulfate-reducing bacteria in industrial circulating cooling water systems. It is applied in chemical plants, power stations, and other industrial facilities to monitor microbial corrosion risks, as these bacteria produce hydrogen sulfide that can damage metal pipelines and equipment. The method provides a quantitative basis for water treatment adjustments to prevent biofouling and corrosion.
