The publication describes the properties of natural water, presents standards and regulatory documents on the quality of water for consumers - industrial, energy, and domestic. Modern methods of water treatment technology are outlined (except for the so-called pre-treatment methods and some others). Information about materials, reagents and equipment, and technological calculations is provided.

For specialists in the field of water treatment, engineers of other specialties who want to get acquainted with this branch of technology. The book may be useful to students of higher and secondary educational institutions.
