No health hazard data are available and no limits for workplace exist. Ozonated water in high concentrations can lead to eye and skin irritation. Langlais et al. (1991) summarize some LC50-values (concentration that is lethal to half of the test animals) found in fish... [Pg.7]

By adding carbonate to ozonated water, the half-life of ozone can be increased. Even some few pmoles decrease the decay rate of ozone by about a factor of ten or more (Hoigne and Bader, 1977). Increasing the concentration of bicarbonate/carbonate up to a concentration of 1.5 mM increases the stability of ozone. Thereafter no further stabilization occurs (Forni et al., 1982). [Pg.14]

The reduction in DBP-formation also depends on the specific ozone consumption. Typical reductions are in the range of 10 to 60 % (compared to non-ozonated water), at specific ozone dosages between 0.5 to 2 g 03 g 1 DOC initially present. If bromide is present, brominated organic DBPs and bromate formation may occur. [Pg.25]

Materials in the whole system must be appropriate, that means reactor and piping for ozone gas as well as for ozonated water must be chosen carefully. For example, the material of the reactor and sampling system, especially the seals, has also to be chosen to avoid not only corrosion from ozone, but adsorption of the compound(s) being studied. It is advisable to let the liquid phase contact only glass and stainless steel. In stirred reactors for example, the stirrer seals (unless the stirrer is a magnetic bar) and all connectors for piping are best placed at the top of the reactor, so that the liquid does not come in contact with them.
