The article describes the automated closed water supply system based on industrial controllers OWEN, which allows creating the necessary fish habitat, increasing the population growth rate, rational use of production areas, conducting experiments on fish breeding, improving their characteristics. The need to develop the different modes of the system operation, in particular, temperature modes, oxygen concentration levels, feeding periods, etc., was taken into account when creating a software package written in the programming language FBD. The developed system includes lower, middle and upper levels. Control over the operation of the closed water supply system is carried out by monitoring. Fish feeding process is automated. Water purification is carried out in the non-stop regime, which decreases the amount of water used, lowers the costs and meets the principles of rational use of natural resources protecting the environment. It is possible to create the necessary dynamic modes of the system for the correct development of embryos and the effective development of various fish species and the possibility of using laser radiation of the required power. The system is controlled by a personal computer using the MasterSCADA package

Purpose: development of a layout-design solution for water intake from a surface water body, excluding the entry of harmful aquatic organisms into fish-breeding reservoirs. In accordance with modern ideas about water intakes that meet the requirements of fish protection and prevent the ingress of aquatic organisms into water supply system of fish-breeding complexes, filtering water intakes are the most effective. Materials and Methods. The water intakes structures development is based on the materials of the fish and water body surveys and the results of the analysis of developments in this area. Results. As part of water nutrition system of the fish-breeding complex, it is proposed to use a water intake with a two-chamber water inlet equipped with filtering panels and regulating screens. Filtering panels located at the head of each of the chambers ensure the retention of harmful, weed and predatory aquatic organisms, and the screens ensure the water inlet shutdown at replacing the filtering panels. Various modes of water inlet chambers operation are considered for intake of various water flows, replacement of filter cassettes and shutdown of water intake operation. It is proposed to use a filtering panel with impervious chambers, which make it possible to simplify the cleaning of its filler as a filtering element. Conclusions. A layout solution for a filtering water intake as part of water nutrition system of the fish-breeding complex has been proposed and developed. The design of a two-chamber water intake based on the use of filter panels and impervious screens, providing fish protection functions and preventing harmful, weed and predatory species of aquatic organisms from entering the water supply system is developed. A technology for water inlet functioning under various operating modes of the water intake has been developed. It is proposed to use a filtering panel with a simplified scheme for cleaning it from colmatation products as a water inlet element of the water intake.

The presence of some chemical compounds at higher levels than maximum permissible concentrations (MPC) in the drinking water, suggests of water resources pollution. In this paper the following elements were analyzed: total arsenic, cadmium, lead, cooper and zinc. Twelve samples of water from the water supply system from the city of Skopje were examined during one year from three different springs. Also, ten samples of bottled water from three producers from the Macedonian market were tested.The determined average mass concentrations of total As, Cd(II), Pb(II), Cu(II) and Zn(II) in the analyzed water samples from the water supply system are 1.35 μg/l, 0.06 μg/l, 0.6 μg/l, 0.9 μg/l and 1,12 μg/l, respectively, and for the tested bottled water, the mean values ranges from 0.56 - 0.83 μg total As / l, 0.053 - 0.056 μg Cd(II)/l, 0.51 - 0.54 μg Pb(II)/l , 0.6 - 0.87 μg Cu(II)/l and 0.68 - 0.8 μg Zn(II)/l water.The following instrumental analytical methods and techniques were used for the analysis of the tested samples of drinking water: flame atomic absorption spectroscopy (AAS), atomic absorption spectroscopy with hydride cеll, electrothermal atomic absorption spectroscopy.The obtained results are shown in tables and graphic form. According to the obtained results a comparative analysis was carried out indicate that it is a water of good quality that can be used in different branches of the process industry.The obtained results in this paper do not exceed the values of the MPC of the Republic of Macedonia prescribed by the legal regulations for the drinking water, which confirm the health safety of the drinking water from the water supply system in the city of Skopje and the packed waters from the Macedonian market in relation to the tested elements.

Работа посвящена системному анализу данных показателей исходной воды при производстве питьевой воды в системе центрального водоснабжения крупного населенного пункта. На сегодняшний день на фоне увеличивающегося негативного антропогенного воздействия на окружающую среду наблюдается ухудшение состояния многих источников питьевого водоснабжения в широком спектре показателей, в частности, таких как органолептические свойства воды. Как следствие, возникает проблема и для питьевой воды. В работе приводится процесс подготовки данных о параметрах исходной воды, забираемой из водохранилища, которые ежемесячно (с 2002 по 2014 год) учитывались на предприятии при дезодорации воды. Приведенные параметры оказывают существенное влияние на органолептические свойства конечной воды. Подготовка данных для анализа проводится методом главных компонент К. Пирсона. Данные, полученные в пространстве R9, переводятся в пространство меньшей размерности R3. Понижение размерности позволяет снизить автокорреляцию между компонентами. Отбор компонент в пространство R3 проводится по правилу Парето. В пространстве R3 методом сферической кластеризации данных «Форель» с постоянным радиусом группировки проводится кластеризация. Приводится пошаговое визуальное представление алгоритма кластеризации в пространстве R3. В работе показано, что в данных показателях качества исходной воды имеются кластеры. Проводится корреляционно-регрессионный анализ данных, представленных в главных компонентах. Строятся регрессионные зависимости показателей органолептических свойств от главных компонент из пространства R3.
