Abstract
A method of reusing waste-water resulting from hydrocarbon production operations as a disinfectant. The method includes a) providing waste-water resulting from hydrocarbon production operations containing greater than 3 ppm bromide ion; b) adjusting the pH of the waste-water to a pH that renders the fracturing fluid non-scaling, while maximizing the production of hypobromous acid and c) adding a sufficient amount of an oxidizing agent to convert the bromide ion to hypobromous acid to provide a disinfectant solution.
