- Abstract:
- A new pipeline cleaning technology—ice slurry cleaning technology was introduced. The technology cleans the inner wall of the pipeline by injecting ice slurry to remove mineral deposits, biofilm and other deposits from the pipeline, which has the advantages of no pipeline excavation, less time consuming, quick restoration of water supply and no secondary pollution. According to the cleaning results of small diameter ductile iron water supply pipeline, turbidity of the pipe network water decreased by about 76% after the ice slurry cleaning, the cleaning effect was good, and the water quality after cleaning also could meet Standards for Drinking Water Quality (GB 5749-2006).
