⭕ A. Ultra violet rays treatment
⭕ B. Lime treatment
⭕ C. By using potassium permanganate
⭕ D. Chlorination
📚 Explanation:
The most suitable method for disinfecting swimming pool water is Ultra violet (UV) rays treatment.
🔹 UV rays effectively kill bacteria, viruses, and pathogens without adding chemicals.
🔹 This method is widely used for **swimming pools**, especially in foreign countries and high-standard facilities.
Why not other methods?
🔸 Lime treatment: Used for softening water, not disinfection.
🔸 Potassium permanganate: Used for treating well water having low bacteria count.
🔸 Chlorination: Common for pools but UV treatment is more effective and safer for skin and eyes.

Key Points on Disinfection of Swimming Pool Water:
- UV treatment: Highly effective, chemical-free disinfection.
- Potassium permanganate: Suitable for low-bacteria well water only.
- Lime treatment: Used for softening, not disinfecting.
- Chlorination: Common method but UV is more efficient & safer.
