Some recent research has indicated that a new technology may have thepotential to lower bromide concentrations in drinking water sources. Electrolysisis used to oxidize bromide to bromine (Br₂) which is volatile. Bromine would hydrolyze to hypobromous acid or hypobromite at pHs greaterthan 3.4. However, at the anode where bromide is oxidized to bromine, water can also beoxidized to hydrogen ions and oxygen, producing a very low pH and significant volumes of very fine oxygen bubbles, favoring bromine over hypobromite. Under these conditions bromine willvolatilize. In recent studies, this process has been shown to be able to removeup to 45% of bromide found the California State Water Project, a source ofdrinking water for 40 million people in California and a source that can have veryhigh bromide concentrations. The objective of this paper is to present modificationsto this process to increase bromide removal efficiency. Includes 5 references, table, figures.
