The correct answer is option 'A': 1 only.
Ultraviolet (UV) radiation plays an important role in water purification systems by inactivating or killing harmful microorganisms present in the water. It is a highly effective method for disinfecting water and ensuring its safety for consumption. Let us dive deeper into the role of UV radiation in water purification:
1. Inactivation of Microorganisms:
- UV radiation has the ability to inactivate or destroy microorganisms such as bacteria, viruses, and parasites present in water.
- When water is exposed to UV light, the radiation damages the DNA of these microorganisms, preventing their replication and rendering them harmless.
- This process effectively eliminates the risk of waterborne diseases caused by these microorganisms, ensuring that the water is safe for consumption.
2. Odour Removal:
- UV radiation does not directly remove undesirable odours from water. It primarily focuses on disinfection and inactivation of microorganisms.
- Odours in water are usually caused by the presence of organic compounds or chemicals that are not affected by UV radiation.
- Therefore, UV radiation alone may not be sufficient to remove odours from water. Additional treatment methods like activated carbon filtration or chemical treatments may be required to address odour-related issues.
3. Sedimentation and Clarity:
- UV radiation does not directly quicken the sedimentation of solid particles or improve the clarity of water.
- Sedimentation and clarity of water are typically improved through processes such as coagulation, flocculation, and sedimentation tanks.
- These processes involve the addition of chemicals that cause the particles to clump together and settle at the bottom, resulting in clearer water.
- UV radiation is primarily focused on disinfection and does not have a direct role in sedimentation or clarity enhancement.
In conclusion, the correct statement regarding the role of UV radiation in water purification is that it inactivates or kills harmful microorganisms in the water. UV radiation does not directly remove odours or improve the sedimentation and clarity of water.
