Investigating corrosion deposits in drinking water supply and distribution pipelines

Summary

The results of investigating the sludge and deposit structure in drinking water supply and distribution pipelines are presented. The literature and experimental data on the structure and composition of corrosion deposits on the pipe walls depending on water quality, pipe material, diameter and age were analyzed. The data on physical and chemical composition of deposits and photomicrographs of corrosion deposits received with the help of a scanning electron microscope are presented.

Key words

sludge , water quality , water supply and water distribution system , corrosion deposits , scanning electron microscope
