Te Growing Challenge of Organic Pollutants in Water

Water pollution leas one of the mogt presssing environmental and public health issees of our time.

Co je to Ozonation?

Ozonation is a water treament process that uses ozone (O 'monation (O' monation); FLT: 0 '3; FLT 1; FLT: 1' 3; FLT; FLT 3; Triatomic accessule consiting of three oxygen atoms, as a powerful oxidant. Ozone is generate on- site by passing dry air pure oxygen contragh a high- voltage electricail discharge or ultraviolet macht.

Mechanisms of Ozone Action

Ozone can oxidize organic actornants protgh two primary pathawas: direct aulular ozon reaction and indirect radical- mediated oxidation. Direct reaction is selektive, targeting compounds with specific functional groups such as unsavated bonds, aromatic rings, and nuophilic sites. In contrast, thee indirect patway complives te dekompention of ozon in water to produce highly reactive hydroxyl radicals (• OH).

How Does Ozonation Remove Organic Pollutants?

Te dembal of organic accordants by ozonation concess treamgh setral chemical stages. Initially, ozone or hydroxyl radicals cleave e accordular bonds, breaking large, complex clarvant accorsules into smaller fragments. These fragments may undergo further oxidation to eventually form carbon dioxide and water. For example, atrazin - a common herbicide - undergoes dealecylation and decalonation upon ozonationationon, losing its herbicitay.
