Bromide in Water

Source of Bromide: Bromide (Br−) is the anion form of the element bromine.

Bromide can react with chlorine and naturally occurring organic matter in drinking water, forming carcinogenic trihalomethanes or halogenated acetic acid disinfection byproducts. Bromide can also react with ozone to form bromate.

 

Health Effects of Bromide: The main health concern is related to the carcinogenic THMs and bromate. Studies indicate an increased chance of cancer in the gall bladder, esophagus, kidney, breast, liver, pancreas, stomach, prostate, colon, and rectum. There is also a risk to pregnant women.

 


How to Remove Bromide:  The Best Available Technology (BAT) for removal of bromide and disinfection byproducts is a WECO reverse osmosis system. A reverse osmosis filtration system with activated carbon filtration will reduce bromine-related contaminants in drinking water by more than 96%.
