Applications
Water Treatment
Potassium Peroxymonosulfate is widely applied in municipal and industrial water treatment systems due to its strong oxidation potential and chlorine-free properties. It efficiently decomposes organic matter, ammonia nitrogen, and hydrogen sulfide, improving water transparency and odor quality. PMPS oxidizes iron and manganese ions, converts nitrite to nitrate, and enhances the overall purification process. Its stable and safe decomposition into non-toxic by-products makes it suitable for advanced oxidation processes (AOPs) used in wastewater recycling and decentralized water purification facilities.
Aquaculture
In aquaculture systems, Potassium Peroxymonosulfate helps maintain a clean and healthy environment for shrimp, fish, and shellfish farming. It removes organic residues and harmful gases from pond bottoms, prevents algae blooms, and reduces bacterial infections. Regular use of PMPS minimizes ammonia and nitrite accumulation, thereby improving dissolved oxygen levels and water stability. Its non-residual nature ensures safety for aquatic organisms while maintaining ecosystem balance.
Livestock and Poultry Farming
Potassium Peroxymonosulfate is an effective disinfectant in livestock and poultry environments, capable of destroying viruses such as ASFV, FMDV, and avian influenza. It is used for disinfection of barns, cages, tools, vehicles, and air ventilation systems. The compound can also be applied in waterline sanitation, preventing microbial biofilm formation and ensuring clean drinking systems for animals. Compared with chlorine-based disinfectants, PMPS produces no toxic residues and is non-irritating to animals and humans.
Food and Beverage Processing
In the food industry, Potassium Peroxymonosulfate serves as a safe oxidizing and cleaning agent for processing lines, utensils, and equipment surfaces. It removes biofilm and organic contamination, ensuring sanitary conditions in dairy, beverage, meat, and seafood production. PMPS also helps maintain hygiene in cold storage and transport facilities. Its high stability and low corrosiveness make it compatible with stainless-steel systems and automated cleaning-in-place (CIP) systems.
Medical and Public Health Disinfection
Potassium Peroxymonosulfate is utilized for high-level surface disinfection in hospitals, laboratories, and public facilities. It effectively inactivates bacteria, fungi, and viruses, including enveloped and non-enveloped pathogens. PMPS-based formulations are commonly used for floor, wall, and medical instrument disinfection due to their rapid efficacy and mild odor. The product’s chlorine-free nature reduces corrosive damage to metal and plastic surfaces, providing long-term safety in healthcare settings.
Textile and Paper Industry
In the textile industry, Potassium Peroxymonosulfate functions as a bleaching and desizing agent, offering high whiteness and minimal fiber degradation. It can replace chlorine-based oxidants, ensuring a safer, eco-friendly production process. In the pulp and paper industry, PMPS aids in decolorization, effluent purification, and fiber surface modification. It enhances brightness stability and helps meet strict environmental discharge standards.
Chemical and Industrial Applications
Potassium Peroxymonosulfate serves as an oxidant and initiator in organic synthesis, polymerization, and fine chemical production. It participates in oxidation reactions such as hydroxylation and epoxidation, supporting the synthesis of pharmaceuticals, agrochemicals, and specialty intermediates. PMPS is also used in electronics, battery materials, and advanced oxidation systems where precise, residue-free oxidation is required.
