The Realities of the Present and Future Prospects of Drinking and Technological Water

Abstract

Key words: ABSTRACT Artesian water Water treatment Aerator-oxidizer Frequency ofpulsations Shear rate of flowThe article analyzes the environmental problems of Ukraine related to the pollution of the Dnipro River as the main source of drinking and technological water supply. The necessity of using artesian waters for drinking water supply is substantiated. The basic problems of quality due to the presence of pollutants in the artesian water are determined. The analysis of modern aeration methods of iron removal from water was carried out. The description and principle of the operation of new technological equipment for the intensification of the purification of artesian water from iron compounds is presented. The efficiency of iron removal from artesian water by discrete-pulse energy input in the aeration water treatment is determined.The results of experimental studies of iron removal from artesian water during various treatment regimes and design features of an aerator-oxidizer are given. The energy and technological parameters of the proposed method of artesian water treatment are given in comparison with the corresponding indicators of other methods of iron removal. The rational parameters of the process taking into account the energy and technological characteristics of the proposed method are established. It is determined that the proposed method of artesian water treatment contributes to the solution of environmental problems at the expense of energy-saving heat and mass exchange equipment for the preparation of drinking and technological water.

“…Одним із найбільш поширених забруднювачів природних вод є високодисперсні тверді частки різної природи, що утворюються в результаті як природних, так і антропогенних процесів [1]. У більшості випадків вони являють собою частинки глини, піску, ґрунту, що утворюються в результаті розмивання русла водними потоками та живих організмів і їх залишків незначних розмірів, що не осідають у водному середовищі.…”
