How to Purify Water
Chemical disinfection is a common method for making water safe to drink when boiling is not an option. This tool calculates dosages based on standard concentrations.
Important Considerations:- Cloudy Water: If the water is cloudy, first filter it through a clean cloth, paper towel, or coffee filter. Then, double the disinfectant dosage.
- Wait Time: The recommended wait time is crucial for the disinfectant to work. For very cold water, it's best to double the wait time.
- Smell Test: After waiting, the treated water should have a slight chlorine or iodine smell. If it doesn't, add another dose and wait again.
