- Abstract:
- A pilot-scale device of pipe network system was constructed in a water treatment plant in order to investigate the influence of different disinfection methods (UV disinfection, UV/chlorine disinfection and chlorination) on the drinking water quality and pipe corrosion. According to the morphological characteristics of the pipe scale, the scale formation time of chlorination was shorter than that of UV/chlorine disinfection. In addition, the analysis of pipe scale components in both UV disinfection and UV/chlorine disinfection showed that the ratio of α-FeOOH to γ-FeOOH+β-FeOOH+Fe3O4 was greater than 1, indicating that the UV disinfection and UV/chlorine disinfection inhibited the corrosion of the pipe network.
