Influence of Ecological Conditions of Water Sources on Water Supply of a Megalopolis

SUMMARY

In theory the improvement of conditions of surface sources of water supply is an effective method of enhancement of potable water quality. However, even if there are possibilities to realize nature-conservative measures they have long-term character. In practice the most realizable methods are correction of water quality at water treatment stations’ water intakes changing the hydrologic conditions and operative control over water treatment at water treatment stations. The application of classical technique of water treatment with coagulation and clarification in complex with ozone sorption and ultrafiltration makes it possible to ensure the necessary degree of water treatment and its compliance with the perspective normative requirements regardless of conditions of a water supply source.
