| description | The present invention relates to a method and system for monitoring and controlling the process train of ozonation and biologically aerated filtration used in water and wastewater treatment. The process monitoring and control can be achieved by online measurement of UV/Vis absorption at one or multiple wavelengths and oxidation/reduction potential values which are compared to predetermined UV absorption and oxidation/reduction values. The air and ozone dosage of the effluent are then adjusted based on the measured values of UV/Vis absorption and oxidation/reduction potential of the effluent. |
