Brominator for disinfection


Bromine is a halogen non-metallic element that is a powerful oxidizing agent in the presence of water. Bromine is generally used for water purification compounds as an emulsifier in many citrus-flavoured soft drinks, to make brominated vegetable oil, in sanitizers, medicines, etc.


The brominator is a cartridge type disinfectant for non-municipal drinking water. Bromine, like chlorine, is a powerful oxidizer, with an improved ability to be effective over a wider pH range than chlorine and has a similar required contact time to be effective.


The Brominator is a slow releasing disinfecting apparatus where the cartridges can be replaced from time to time (once a fortnight, or once a month, depending on the daily water requirement and the application). The product consists of white solid tablets that have a solubility of 2g per litre in water. The concentration in product water should be between 1 and 3 mg/L. One cartridge can treat approximately 100 000 L of water at a concentration of 5mg/L application.


When bromide is added to water it forms hypobromous acid and hydrobromic acid:


Br2 + H2O = HOBr + HBr
Hypobromous acid (HOBr) is used as a disinfectant to kill cells of many pathogens.


Where the source water contains silt or organic matter, pre-filtration is recommended to remove these contaminations prior to the disinfection stage offered by the Brominator. The finer the pre-filtration the more effective the Brominator can disinfect the water. The preferred level of pre-filtration is 5 micron or finer.
