A system that integrated with disinfection inspection

sanitization enhancement

and communication modules is developed to minimize city water secondary contamination.The whole system circuit schematics and software flowchart are provided.A corresponding testing model is designed based on effective chlorine measurement theory.Laboratory tests show that the volume fraction of effective chlorine can be controlled at 0.3×10-6.The city water quality can be maintained well with additional effective chlorine and 285nm UV sanitization process.The real-time inspection results are transmitted to the water factory by wireless communication modules to improve the factory ability to adjust water condition quickly.
