О возможностях подготовки питьевой воды из поверхностных источников Сирии

Abstract

The purpose of the study is to assess the possibilities of combining the processes of mixing coagulant and agitating (formation of flocculant), developing, designing and testing the installation that ensures the compatibility of processes and the use of compressed air in the mixing process to achieve standard indicators of drinking water quality at the lowest possible economic costs. The article contains the results of research to assess the possibilities of achieving the quality indicators of drinking water from surface sources of the Syrian Arab Republic in conditions of regulated runoff. The experiments used water from reservoir 16 Tishrin, as a coagulant aqueous aluminum sulfate [Al2 (SO4)3. 18H2O], water samples for experiments were stored until a temperature close to ambient temperature was reached. A combination of a flocculation chamber and a mixer for a water purification plant is proposed, as well as a method for using compressed air as a mixing factor instead of mechanical mixers. Before the start of the experiment, measurements of the temperature and pH of the water were carried out, as well as the calculation of the amount of air required to perform the processes of mixing and the formation of a flocculant. Due to the combination of the mixer and the flocculation chamber, the possibility of increasing the efficiency of water purification and reducing operating costs when using compressed air for mixing has been established; it has also been possible to determine the optimal values of the parameters of mixing and mixing processes used in water treatment; to improve mixing efficiency and water purifi cation quality; to reduce operating costs for water treatment; to optimize the layout of individual elements of the water treatment system.
