Quick Answer
The ideal concentration of iodine in treated water is between 0.5 and 1.0 milligrams per liter (mg/L) for short-term disinfection, and 0.05 to 0.10 mg/L for long-term drinking water storage.
Safe Water Disinfection with Iodine
The World Health Organization recommends using iodine for water disinfection due to its effectiveness against bacteria, viruses, and protozoa. When treating water with iodine, the optimal concentration is crucial to ensure safe drinking water. For short-term disinfection, a concentration of 0.5 to 1.0 mg/L is recommended, and the water should not be stored for more than 24 hours.
Iodine Concentration for Long-Term Water Storage
For long-term water storage, a lower iodine concentration is necessary to prevent taste and odor issues, as well as potential health problems. A concentration of 0.05 to 0.10 mg/L is recommended for long-term water storage, as it provides sufficient disinfection while minimizing potential issues.
Testing and Verification
It is essential to test and verify the iodine concentration in treated water to ensure it meets the recommended levels. This can be done using iodine test kits or field testing equipment. Regular testing and verification are necessary to maintain the effectiveness of the disinfection process and ensure safe drinking water.
