The choice of an environmentally oriented technology for water softening at water treatment facilities

Abstract

The processes of softening drinking water have been studied quite widely, and the technologies used have a wide range of equipment used and aggregation capabilities. The development of membrane technologies provides virtually unlimited technological possibilities for water treatment [1], and classical ion exchange solutions are also widely used, more in industry [2]. Of course, the use of such solutions is associated with certain and considerable operating costs. At the same time, it is a well-known fact that modern softening systems require not only qualified and timely maintenance, but also form wastewater flows. Utilization of the generated wastewater can be a difficult task to solve, despite the advantages of membrane and ion exchange technologies in the processes of drinking water treatment, since water supply organizations are usually underfunded due to the social function of the water supply tariff [3]. This article shows the possibility of implementing environmental technology to reduce water hardness without the formation of associated wastewater. Softening in a suspended layer of sand refers to modern methods of reagent softening of water. These are the so-called devices of intensified softening.
