Centers for Disease Control and Prevention (CDC) – “Potable Water” – Vessel Sanitation Program (VSP)

Variances by Section
Operational Manual Section: POTABLE WATER

Fluorine, chlorine, bromine, and iodine are the elements of the halogen family.
Chlorine is by far the commonly used on land, but look for bromine on ships.

Bromine as a drinking-water disinfectant – World Health Organization (WHO) 2018

April 6, 2019

I’ve been asked about Bromine, this what I found and will podcast it sometime soon. (click here for the full report )

With regards to the advantages of bromine over chlorine:  bromine is more effective in disinfecting bacteria, viruses and protozoan parasites at higher pH levels (pH 9 or 9.5) and in the presence of ammonia;  bromine provides greater protection across a wider pH range; and  bromine is more effective for poor quality water.

The disadvantages of bromine over chlorine include:  the safety of long-term consumption of bromine and its DBPs ( disinfection by-products) when used as a drinking-water disinfectant is not fully established. At present brominated DBPs are generally considered more toxic than chlorinated DBPs (see section 3.6.2); it should be noted that brominated DBPs are also produced in chlorinated water in the presence of bromide.

In 2010, USEPA issued a Final Registration Review Decision for bromine (Case 4015) stating that the use of bromine to treat potable water does not trigger the need for a drinking-water assessment. In addition, the USEPA stated that “Bromine is registered for use to treat/disinfect potable water (examples of potable water system treatment sites include, but are not restricted to, aboard ships and on oil and gas drilling/production platforms).”
