The permissible limit of turbidity of domestic water is ____ ppm.a)5-1...
**Explanation:**
Turbidity is a measure of the cloudiness or haziness of water caused by the presence of suspended particles. It is an important parameter to assess the quality of drinking water as high turbidity can affect the aesthetics, taste, and odor of water, and may also indicate the presence of harmful contaminants.
The permissible limit of turbidity in domestic water is generally specified by regulatory bodies such as the World Health Organization (WHO) and local health authorities. The acceptable turbidity level in drinking water is typically set at a maximum of 5 to 10 parts per million (ppm).
**Reasons for the Permissible Limit:**
There are several reasons why the permissible limit of turbidity in domestic water is set at 5 to 10 ppm:
1. Aesthetics: High turbidity can make water appear cloudy or discolored, which may be visually unappealing to consumers. Setting a low turbidity limit ensures that the water appears clear and visually pleasing.
2. Taste and Odor: Suspended particles in water can contribute to off-flavors and odors, which can affect the taste and smell of drinking water. By limiting turbidity, the taste and odor of water can be improved.
3. Filtration Efficiency: Municipal water treatment plants use various filtration methods to remove suspended particles from water. The lower the turbidity, the more efficient the filtration process becomes. By setting a low turbidity limit, water treatment plants are encouraged to implement effective filtration systems.
4. Health Concerns: High turbidity can be an indicator of the presence of harmful contaminants such as bacteria, viruses, and parasites. These microorganisms can be attached to suspended particles in water. By limiting turbidity, the risk of waterborne diseases can be reduced.
**Conclusion:**
In conclusion, the permissible limit of turbidity in domestic water is generally set at 5 to 10 ppm. This limit ensures that the water is visually clear, tastes and smells good, and is free from harmful contaminants. Compliance with the turbidity limit is important for the provision of safe and high-quality drinking water to households.
