Wprowadzenie to Ozone and Advanced Oxidation in Water Treatment

Water scarcity and increaming pollution from industrial, agricultural, and domestic sources are driving thee water treatment industry to adopt more robutt and efficient technologies. Among the most soculing solutions is the stratec integration of ozoonation with advanced oksydation processes (AOPS).

Co z Ozonationem?

Ozonation uses ozone gas (O o1; Osonatious 1; FLT: 0 + 3; Osonatione 1; Ero1; FLT: 1 + 3; Osonatious, to desite and degrade organic and d inorganic difficiants in water.

Mechanism of Ozone Action

Ozone works through gh two primary pathways: direct oksydation bye direct ozone and indirect oksydation via hydroksyl radicals formed during ozone democposition. Direct oksydation is selective and fast for compounds containg double bonds, activate aromatic rings, or nucleophilic sites. Indirect oksydation, which becomes dominant at hiser pH or in thee presence of radical promoters, is nonselective and far more reactive, attacking neyly any organic evalule.
