Product Label

sodium hypochlorite appears to offer the best mix of low cost, ease of use, safety, and effectiveness in areas where there is enough water to drink and water is not excessively turbid. These characteristics are the reasons why most water treatment systems in the US and Europe have been using chlorine for disinfecting drinking water for nearly 100 years.
Usually an amount in the range of 5 to 10 milliliters added to 20 liters of water is sufficient to inactivate the disease-causing organisms, but not leave an unpleasant taste. Once the size of the cap for your project has been determined, some simple experiments can be used to determine the appropriate dose. To conduct the experiments, you will need Sodium Hypochlorite , source water in your area, and a kit that measures the amount of free and combined chlorine.
Chlorine is an extremely reactive chemical. Right after the sodium hypochlorite is added to the water, chlorine levels decline because the chlorine is reacting with inorganic and organic matter and microbes. After those reactions are complete, chlorine in water will slowly escape into the air as a gas
