It is widely used for sterilization and algae removal in industrial circulating cooling water, oilfield water injection, paper mills, and sewage treatment. This product is a broad-spectrum oxidizing bactericide, which has extremely high bactericidal activity against bacteria and algae, especially against bacteria forming slime. The bactericidal speed is fast, and the lethal amount of bacteria can reach 4 orders of magnitude in a short time, which is particularly suitable for direct current cooling water requiring fast killing or circulating cooling water systems with impact treatment. In alkaline water treatment, its bactericidal activity is much higher than that of chlorine. The corrosion to copper and its alloys is much lower than that of chlorine, and it has good compatibility with copper corrosion inhibitors. Normal use is harmless to humans and organisms and will not cause environmental pollution.
