Each litre of ion exchange resin will thus be able to treat 1100 / 4.4 = 250 litres of the hard water before having to be regenerated. It distills roughly 1 gallon of water per 5.5 hours, by heating the water to 212 degrees, which is the optimum temperature for the right distillation speed for removing contaminants from water. Each litre of ion exchange resin will thus be able to treat 1100 / 4.4 = 250 litres of the hard water before having to be regenerated. Natural oxygen is a mixture of three stable isotopes: oxygen-16 (99.759 percent), oxygen-17 (0.037 percent), and oxygen-18 (0.204 percent). Lead can accumulate in our bodies over time, where it is stored in bones along with calcium.
