Stabilization of corrosive water at the Petrodvoretz water treatment plant

Summary

In order to prevent corrosion in steel water distribution pipelines pilot tests of a water stabilization system fed with water from the South water treatment plant of Saint-Petersburg were carried out at the Petrodvoretz water treatment plant. During the entire period of chemical dosing steel passivation was achieved which provided for the tendency for iron concentration decrease at the test points of the Petrodvoretz water distribution network.
