Prevention of Mold Contamination : Ozone Treatment

Mold is a common pest that can cause diseases and decay property. Moreover, certain mold can produce toxic chemicals which leads directly or indirectly to additional health impacts and economic losses. Therefore, prevention of mold growth is a major concern, and disinfection of mold has become a center of attention. The purpose of this thesis was to study about the effect of ozone in the disinfection of mold and the method of producing ozone. The usage of ozone for disinfection in indoor sector and food sector was studied by reading previous research work to understand the effect of ozone on mold. Similarly, available literature was examined to understand methods of ozone production treatment. Ozone can be produced by electrical or photo-chemical method and it can be used in gaseous form or aqueous form to disinfect mold. Molds of all kinds are killed by ozone. However, concentration of ozone and treatment time vary depending on mold species and form of ozone used. The usage of ozone treatment was more beneficial in the food sector than in the indoor sector
