Choice of Reagent Technology of Anticorrosion Water Treatment for Water-Distributing Network of St. Petersburg
Summary
The secondary pollution of city water in St. Petersburg with iron is caused by the highly corrosive aggressiveness of the Neva’s water, the source of the city water supply. The methods of reducing this water parameter are considered. The technology of neutralization of corrosive aggressiveness based on the injection of calcium chloride and sodium carbonate into water treated has been chosen. The technology of stabilizing water treatment has been introduced at the Sestroretsk and Petrodvorets water supply stations of St. Petersburg.
Key words
