Disinfection technology | Interests | Drawbacks |
Liquid chlorine | Low energy consumption | High storage risk |
UV light | Low investment and operation costs | Inadequate depth of penetration and occupational health risks |
Chlorine dioxide | High efficiency and low operation costs | Inconvenient storage and transport |
Sodium hypochlorite | Low toxicity, simple equipment, stable operation, easy control, and low operation and preparation costs | High energy consumption, strong corrosiveness, and high pollution |
Ozone | The ability of decoloring and deodorizing and quick decomposition of microorganisms | High operation costs and hazardous disinfection by-products (DBPs) |
