Chlorine is the most widely used water disinfectant. When used as directed, the tablets make water safe by killing pathogenic organisms. Chlorine will help prevent stomach upsets & intestinal disorders caused by drinking bacterial contaminated water. As well as for treating drinking water, chlorine can be used to disinfect water for cleaning teeth & for washing fruit & vegetables. Once the chlorine tablet has been used, the neutralising tablet effectively remove the taste & smell of the chlorine from the treated water. This makes the water more palatable for consumption.
