  • Process for treating bromide-containing water using ozone
    Patent number: 5609766
    Abstract: In a water treatment process using ozone, to prevent bromate formation a quantity of bromide-containing water for treatment is first set to a pH value of less than 6.5 by feeding in CO.sub.2, unless the water already contains the requisite CO.sub.2 by origin. CO.sub.2 and ozone are then simultaneously fed in for a period of several minutes. The feed stream of CO.sub.2 is designed to maintain the pH value, and sufficient ozone is fed to the quantity of water to produce oxidation and sterilization.
