Process and device for water treatment by injecting ozone and carbon dioxide

摘要

The flow rate, temperature, alkalinity and pH of the water stream (11) are measured (12) and the quantities of ozone (1) and carbon dioxide (2) injected are adjusted accordingly. The residual ozone, oxygen and Redox potential of the treated effluent are measured (13) and used to in the calculation of the required amount of ozone injection. The outlet pH is also measured to help calculate the required amount of carbon dioxide injection.
