The process of sustainable development of society is impossible without providing people with drinking water of appropriate quality. Experts prove that poor-quality water causes diseases of the blood-vessel system and the intestinal tract [1]. Therefore, a vital problem is to extract and supply water of appropriate quality [1, 2]. The processes of water preparation for both economic and drinking needs of the population and manufacturing needs of industrial enterprises require bringing the physical and chemical properties of water in compliance with regulatory requirements [3]. Various technological workflows are used for this purpose. The choice of a technological scheme of water purification is based on the physical and chemical indicators of the water quality of a natural source. However, it is also necessary to take into account the characteristics of pollutants and the requirements of consumers to water quality, the efficiency of treatment facilities, etc. Surface water often contains suspended substances, characterized by significantly specific color and having a particular smell and taste. Such impurities worsen the physicochemical parameters of water, so they should be eliminated before transporting water through the water supply network. The choice of a method of water preparation is based on studying water quality indicators of the water source (the chemical composition of water) obtained as a result of physicochemical, sanitary-bacteriological and technological analyses and with regard to a number of other indicators. Reagent methods of water purification and discoloration are used most often for cleaning surface water from coarse dispersed, colloidal and other contaminants. The main units in such methods are filtering facilities [1, 4, 5], whose efficiency depends not only on the quality of treated water but also on the operation cost. Filtering structures can be represented by fast filters or contact lighteners [4]. In order to reduce the cost of constructing and operating surface water purification stations, it is necessary to establish correctly the design and technological parameters of the filtering structures. This problem can be solved using mathematical modeling.
