The application of ozone treatment for ammonia removal in spent brine was investigated.
This study investigated the application of ozone in conjunction with Pt/Al2O3 catalysts, called ozone-catalytic oxidation (OZCO) process, to destruct gaseous naphthalene (Nap).
The processes were studied in three groups: processes deriving from the heterogeneous photocatalysis (using TiO2), oxidation systems based on Fenton-type reactions (homogeneous photocatalysis) and processes based on the application of ozone (ozone catalysis).
Additional possible local treatments are a desensitisation by the Er:YAG laser or application of ozone.
Similarly, Estrela et al. [ 21] indicated that the application of ozone gas for 20 minutes in infected human root canals was not sufficient to inactivate E. faecalis.
In the last several years, various in vitro and in vivo experimental and clinical studies have investigated the bactericidal effect of the topical application of ozone in different situations, including the management of infected wounds [ 6- 8].
Regarding the application of ozone gas, the results of the present review are consistent with those of previous reviews [ 55, 56], i.e. there is no clinical evidence for the use of ozone in arresting dentin caries in primary teeth in preschool children.
Protection of crop plants from ozone damage could be accomplished by replacement of sensitive biotypes with more tolerant ones as well as by application of synthetic ozone protectants such as ethylene diurea, azoxystrobin, epoxiconazole and penconazole (Blum et al. 2011; Didyk and Blum 2011).
The relatively low gas liquid mass transfer efficiency and the low activity of ozone in acidic solution limit the application of ozonation.
