Table 1. Effects of air temperature on ozone stability
McClurkin, J.D. and D.E. Maier, 2010
In addition, water temperature plays an important role in the solubility of the ozone gas. The higher the water temperature, the lower its half-life or effectiveness, as shown in Table 2.
Table 2. Water temperature impact on ozone decay
Gardoni et al., 2012
For ozone, a pH of 8.5 or lower is typical with a pH of 7.0 recommended. As organic matter increases the reaction time increases and the half-life of the ozone decreases. Inorganic matter can positively influence the reaction rate of ozone by acting as a scavenger for hydroxyl radicals. So as the concentration of inorganic carbon increases, i.e., the concentration of scavenger hydroxy radicals increases and the decay of ozone decreases.
