Abstract
Stabilized bromine solutions are prepared by combining a bromine source and a stabilizer to form a mixture, adding an oxidizer to the mixture, and then adding, an alkaline source to adjust the pH of the mixture to at least 13.

A method of making a stabilized bromine solution comprising the steps of:
- a. combining a bromine source and a stabilizer to form a mixture;
- b. adding an oxidizer to the mixture;
- and
- c. adding an alkaline source to the mixture to adjust the pH of the mixture to at least 13.
A method of preventing biofouling on the surfaces of equipment in contact with an industrial water system which comprises adding to the water system an effective biofouling controlling amount of a stabilized bromine solution, said solution having been prepared by the steps of:
- a. combining a bromine source and a stabilizer to form a mixture;
- b. adding an oxidizer to the mixture;
- and
- c. adding an alkaline source to the mixture to adjust the pH of the mixture to at least 13.
A method of making a stabilized bromine solution comprising the steps of:
- a. selecting a bromine source;
- b. adding a stabilizer and an oxidizer to the bromine source to form a mixture, wherein the stabilizer and the oxidizer are alternately added to the mixture in an amount sufficient to maintain the pH of the mixture between about 0 and 6.9;
- and
- c. adding an alkaline source to the mixture to adjust the pH of the mixture to at least 13.
