A method of increasing the operating efficiency of an electro
bromination device providing disinfectant to an aq medium, which method comprises
- Passing electric current across an undivided cell through
which is flowing an aq medium contg 800-2000 ppm of bro
mide ions & a N-contg electrobromination-enhancing adju
vant such that bromide ions are electrolytically oxidized to
bromine in the aq medium
under conditions enabling formation in situ of hypobromous
acid, dissociated hypobromous acid, or both, said aq medium contg < 800 ppm of chloride ion such that molar Chloride ion/Bromide ion < 2.3:1, whereby the operating efficiency of the device is increased
