The most common method for microbiological control in industrial cooling systems is gaseous chlorination. Recently, however, with Superfund Reauthorization and community Right-to-Know laws, serious concerns have risen over the safety of gaseous chlorine.

This paper will discuss recent work addressing halogen-based alternatives to gaseous chlorine. The use of an activated bromide mixture, in conjunction with sodium hypochlorite, will be shown to be an effective and economic replacement for gaseous chlorine. In addition, the use of chlorine stabilizer or activated bromide, along with gaseous chlorine, will be shown to be an effective approach to minimizing risks associated with gaseous chlorination. Laboratory and field data will be presented and discussed.
