Abstract: Continuously increasing requirements for the quality of water treatment, changing operating conditions of water treatment facilities, physical and moral wear of equipment lead to the need to improve water treatment systems. However, in conditions of limited funding, you need to choose solutions that optimally combine price and quality. It is impossible to solve such problems without applying system analysis. The work analyzed the problems of water treatment, substantiated the need to use system analysis to solve problems. You have selected functional modeling as the toolkit. To solve the problem, a functional model of a single-stage water treatment scheme was developed and analyzed. The paper presents a context diagram of the water treatment system, a diagram of its decomposition, decomposition diagram of the mixing process and a diagram of the node tree. The analysis of the functional model showed the acceptability of the technology used with the condition of major repairs of the technological equipment.

Keywords: water treatment technology, single-stage diagram, system analysis, functional modeling, process, node tree diagram, context diagram.
