) The TRO formation rates of ozonation and electrolysis treatments
of seawater were found to be linear, with a rate of
7.5 101 mg as Cl2/L-min, and 15.7 mg as Cl2/L-min,
respectively. The major active TRO component of ozonation
in seawater is the secondarily formed HOBr, and not residual
ozone, because of the high reactivity of ozone with Br. In
electrolysis, the key active substance of TRO is HOBr, which
will be produced until all Br consumed, and followed by
OCl accumulation, in a linear pattern.
