Calculators c4-8 through c4-10 are for an air-feed ozone system. For a more rigorous calculation (or for calculations for pressure swing adsorption, vacuum swing adsorption, and vacuum-pressure swing adsorption systems), refer to Ozone in Drinking Water Treatment (Rakness 2005).

A recent review on the mechanisms and goals of ozone and associated oxidation processes in drinking water treatment is provided by Camel and Bermond (1998), while extensive coverage of the subject is found in Langlais et al. (1991).

Ozone is applied in three-phase systems where a selective ozone reaction, oxidation of residual compounds and/or enhancement of biodegradability is required. It can be used to treat drinking water and waste water, as well as gaseous or solid wastes. Especially in drinking water treatment full-scale applications are common, e. g. for particle removal and disinfection, while in waste water treatment sludge ozonation and the use of catalyst in AOP have been applied occasionally. Current research areas for three-phase ozonation include soil treatment and oxidative regeneration of adsorbers. Ozonation in water-solvent systems is seldom studied on the lab-scale and seems favorable only in special cases. In general, potential still exists for new developments and improvements in ozone applications for gas/watcr/solvent and gas/waler/solid systems.

The application of O3 in drinking water treatment is prevalent because of its capability of disinfection and oxidation. Ozone, as a disinfectant, is unstable in water and undergoes reactions with water components, whereas O3 decomposes to OH so that advanced oxidation occurs. Unfortunately, undesired oxidation/ disinfection by-products (DBPs) can be formed from... 

Ozone is residue-free in water due to its self-decomposition into oxygen. As described above, ozone has been extensively used in water and wastewater treatment since its first full-scale application in drinking water treatment at Oudshoorn, Netherlands, in 1893. To date, ozone has been used full scale for disinfection and purification of ground and surface waters, treatment of municipal and industrial wastewater, and treatment of swimming pool and cooling tower waters.P 4 1 1... 

Chemical oxidation shows several potential benefits compared to other treatment options. The main advantage is the possible minerahzation of organic substances to carbon dioxide and water. The substance can be completely de-structed and is not only simply enriched or shifted into another phase [33]. Furthermore, there is also a disinfecting effect if ozone is used. Ozonation is the oxidative treatment process most widely spread in drinking water treatment—though it is mainly implemented for disinfection and the oxidation is only considered a beneficial side effect [28]. 

The elimination of MTBE and alternative ethers from water with pure ozonation is only possible if sufficient OH radicals are created. This is highly dependent on the type of water treated and high ozone doses are needed for a measurable concentration decHne. These doses are higher than usually applied in drinking water treatment [25,66].

Ozone is a strong oxidising agent and it has been used for many years as a disinfectant in drinking water production. Bott [1990] has compared chlorine and ozone in cooling water treatment. Edwards [1983] compares the oxidising power of some common water treatment chemicals and he concludes that ozone is the most powerful. Table 14.12 gives the comparison. Bott and Kaur [1994] have reviewed the use of ozone in water treatment.
