- Abstract:
- Concentration of total aluminum and different aluminum species in a water distribution system of city A with sample numbers of more than 5 000 was statistically analyzed. The total aluminum concentration at terminal nodes of pipe network varied with time and space. There were differences in the total aluminum concentration at different terminal nodes at the same time and at the same terminal nodes at different time. The distribution characteristics of aluminum species were as follows: the higher the concentration of total aluminum, the higher the concentration of particulate aluminum. Based on the difference mechanism analysis of total aluminum concentration at terminal nodes of water distribution system, it was found that the fundamental reason for the difference was the change of aluminum species during the whole water distribution process.The equilibrium principle of heterogeneous aluminum system was an important theory to explain the difference.
