Bromine, a member of the halogen family, serves as a potent disinfectant in industrial water treatment. Its effectiveness, especially in swimming pools, spas, and cooling towers, arises from its ability to operate efficiently in the presence of ammonia and other nitrogenous compounds. Unlike chlorine, bromine remains active and potent across a broader pH range, making it a suitable choice for various industrial applications.

While bromine is an excellent disinfectant, its reactive and corrosive nature calls for stringent safety measures. Elemental bromine can cause acute health issues upon dermal contact or inhalation. This necessitates rigorous monitoring of bromine levels in water systems to safeguard the health of workers and end-users.

Bromine in water systems can produce disinfection byproducts (DBPs), much like chlorine. These DBPs, especially when discharged into natural water bodies, can have environmental implications. Monitoring bromine levels is therefore essential to manage its environmental impact effectively.

Bromine testing in water often employs methods like the DPD and OTO, which are also used for chlorine testing. These methods rely on a color change to indicate the presence and concentration of bromine. In industrial settings, more sophisticated methods might be used for accurate and continuous monitoring.

Managing bromine levels in industrial water systems is challenging due to its highly reactive nature. Ensuring safety and effectiveness requires robust systems and processes. This includes using corrosion-resistant materials in bromine handling and treatment equipment and establishing strict safety protocols.

Compliance with environmental and health regulations is crucial when using bromine in industrial water treatment. Regular testing and adherence to permissible levels ensure compliance with regulations, avoiding potential legal and financial consequences.
