21 Claims

1. A method for producing hypobromite comprising:

combining together bromide, hypochlorite, and acid to provide a reaction mixture, wherein the acid is included in a sufficient amount so that the reaction mixture has an initial value of log m(OH⁻) that is in a range from −2 to −5; and

reacting the reaction mixture to form hypobromite.

14. A method for producing hypobromite in a reactor, the method of comprising:

adding bromide, bleach, and acid to the reactor as a reaction mixture, wherein the bleach includes a base;

reacting the reaction mixture to form hypobromite in a reacted mixture;

measuring a parameter of the reaction mixture that is indicative of at least one of a rate of reaction and reaction progress; and

controlling an amount of acid that is added to the reactor based on the measured parameter and so that the pH_mof the reacted mixture is in a range of from 11.69 to 9.71.
