Dose-paced control optimizes efficiency of the UV disinfection process by modulating lamp output power based on real-time data.
For instance, if UVT increases in the incoming water to the UV disinfection system, control mechanisms are in place to turn off unneeded lamps or lower lamp output power. This results in lower energy consumption while still meeting disinfection objectives.
Similar to capital costs, small changes in UVT can have a powerful impact on annual operating costs of the UV disinfection system. For example, a wastewater plant with design flow of 61 mgd (48 mgd average flow) could realize over $60k annual savings in operating costs with a just 5.0% increase in the average UVT of the water entering the UV disinfection stage.
