Description
Summary:This article describes research on the application of ozone technology for the purification of surface water in the presence of bromides. The pilot system used multistage contact columns for water-ozonation processes with stabilized contact time. The research has shown that the basis for limiting the formation of bromates is the optimum amount of residual ozone after the ozonation process and the constant time of ozone contact with the water. This solution allows us to reduce the formation of harmful compounds and apply ozone technology with water containing carcinogenic precursors.
