INTRODUCTION

Bromine is added to water to kill bacteria and other disease-producing organisms,
control algae, and remove undesirable odors and colors. Bromine added to water,
forms hypobromus acid, the sanitizing form of bromine. Bromine forms free available
bromine and combined bromine or bromamines. Combined bromine is a very active
sanitizer.
