-
Chemical-Free Treatment: Ozone decomposes naturally into oxygen, requiring no storage or handling of hazardous chemicals, and produces no harmful byproducts.
-
Environmentally Friendly: By boosting dissolved oxygen levels and minimizing disinfection byproducts such as THMs, ozone enhances overall plant process efficiency.
