It is an oxidizing bactericide with strong bactericidal power, suitable for the treatment of moss and algae in general circulating water systems. It has a low dosage, broad-spectrum, and has excellent bactericidal effects on algae, fungi, bacteria, and Legionella, etc. It has low volatility, and the effective bactericidal concentration in cooling water can be maintained for a longer time, saving the amount of medicine. It has a low decomposition rate of other water treatment agents (such as organic phosphate scale inhibitors, dispersants, and copper corrosion inhibitors) and good compatibility. It decays rapidly, and the discharged water will not cause environmental pollution and the trouble of wastewater treatment.
