ALGORITHM FOR OPTIMAL STRUCTURE FORMATION OF FILTER MODULE IN THE PROCESS OF DRINKING WATER PURIFICATION

Abstract

The scientific-practical problem of the regulation of chemical parameters of water quality, namely concentrations of sodium, calcium, magnesium, potassium at the outlet of filters, which in turn is an integral part of the scheme of the process of purification of drinking water, is considered. An algorithm for the formation of an optimal structure of the ion exchange filter module and the structure of the control system that implements this algorithm is proposed. The analysis of filters for water purification showed that they are mainly intended to reduce rigidity, turbidity, purification of iron, sulfates, chlorides, nitrates and organic impurities. The proposed work is devoted to increasing the efficiency of water purification from such elements as magnesium, calcium, tri-potassium and potassium, or more precisely, to normalize these indicators to the values defined by the state standard, which involves the introduction of appropriate ion-exchange filters. The aim of this article is to develop a control system algorithm, which increases the efficiency of the stage of fine water purification by forming the optimal structure of the module of ion exchange filters and determining the appropriate flow of purified water. It has been determined that the ion exchange filter is a periodic apparatus and, in order to ensure the continuity of the purification process, the filter module must contain backup capacities in the form of additional filters of different purposes, which creates the preconditions for optimizing the structure of the specified filter module. On the basis of the analysis of the current state of the equipment for purification of drinking water, an algorithm for determining the optimal structure of the module for ion exchange filters and the corresponding flow of purified water is investigated. Implementation of the control system based on the given algorithm will increase the efficiency of the stage of fine purification of the installation of water treatment.
