However, in water sources containing bromide, the allowable dose of ozone can be severely limited by the bromate limits. Because of the high reactivity of ozone, a residual is short-lived and difficult to measure. Plus operating and maintenance costs for ozone systems are high. Chlorine dioxide systems are much less expensive to install.
