ABSTRACT:
A method for purifying source water to obtain sterile, low-sodium water is described. The improved method employs ion-exchange, adsorption, filtration by particulate size, ultrafiltration, and reverse osmosis in combination with a closed holding system requiring only 2-3 ppm chlorine for sterilization. A method for storing treated water sterilized with chlorine, keeping the chlorine uniformly distributed during storage, and for removing the chlorine just prior to using the water while maintaining sterility of the water is also disclosed. An additional aspect of the invention is novel sterile filtration means, disclosed for removing chlorine from treated water, comprising a receptacle for activated carbon particles, having a water inlet and a water outlet, yet which is sealed from contamination from airborne microbes, and an effective number of carbon particles. The novel filtration means is wholly autoclavable.
