Abstract: | This paper presents the designer's role in providing an efficient and reliable ozone system for use in water treatment. The 789 m3/h (5 mgd) regional water plant in Avon, Colorado, USA is used as a case study. In the process design, two alternatives were evaluated. The ozone alternative was selected based on its multiple benefits. These benefits included iron and manganese removal, taste and odor control, coagulation and disinfection. Each aspect of the ozone system design is reviewed. |
