Jan 1, 2021 路 The present chapter provides an overview about ozonation processes in drinking water treatment. It presents some fundamental and practical aspects regarding ozonation. The chapter also discusses the reactivity of ozone in aqueous solutions and presents important mechanistic and kinetics aspects.

reactions are very rapid and contact time is short. Treatment of drinking water with ozone also can disinfect the water by killing bacteria and inactivating viruses present in the water. 1. Introduction Water rapidly absorbs both natural and man-made substances generally making the water unsuitable for using prior to some form of treatment.

Ozone In Waste Water Treatment - EOLSS

The combination of biological treatment with ozonation is the most important approach to apply ozone in the field of waste water processing.

Ozone is used in many industries. It is used for purifying air and drinking water, in industrial waste treatment, oils, bleaching and waxes, and to make other chemicals. Some examples of workers at risk of being exposed to ozone include the following: Outdoor workers in areas with high levels of ozone; Factory workers in paper and pulp mills
