title: [Study of ozonization effects on mineral water components].
abstract: The disinfection effects of ozonization and its influences on chemical components of mineral water were investigated. The results showed that ozone at the level of 0.5 mg/L and with the exposure time of 5 minutes effectively destroyed bacteria in mineral water. High level ozone showed no strong influences on some beneficial components, such as strontium and metasilicate and on some main components, such as bicarbonate, hardness and alkalinity, but slightly elevated pH value. Ozonization reduced the contents of total dissolved solids and oxygen demand, and decomposed some reductive contaminants such as ammonia, cyanide and phenols. Ozonization will convert part of the bromide into hypobromite and bromate.
