1. Water Treatment
- Drinking Water Disinfection: It eliminates bacteria, viruses, and protozoa (e.g., E. coli, hepatitis A, Giardia) in water sources, preventing waterborne diseases.
- Swimming Pools & Spas: Used to oxidize organic contaminants like body oils, sweat, and algae, maintaining clear, microbe-free water.
- Industrial Wastewater: Breaks down organic pollutants and inactivates pathogens, reducing BOD/COD levels before discharge or reuse.
2. Bleaching
- Textiles: Removes natural pigments and impurities from cotton/linen fibers, enhancing dye absorption.
- Paper Industry: Historically used to bleach wood pulp by oxidizing lignin, though eco-friendly alternatives are now preferred.
3. Sanitization in Industries
- Food Processing: Sanitizes equipment, surfaces, and production water to prevent microbial growth, with strict dosage control to avoid residues.
- Livestock Farming: Disinfects barns, poultry houses, and drinking water to curb disease spread among animals.
4. Aquaculture
Controls harmful algae, bacteria, and parasites in ponds, creating a safe environment for fish and shrimp. Dosage must be carefully managed to avoid harming aquatic life.
