Установлено, что в процессе эксплуатации фильтра кварцевый песок трансформируется в композитный материал с покрытием из оксидов алюминия и железа, которые образуются в результате адсорбции и осаждения ионов из исходной воды.Методами растровой электронной микроскопии и энергодисперсионного анализа обнаружено, что при работе фильтра на исходной воде с содержанием Al ≈ 0,58 мг/л и Fe ≈ 0,44 мг/л происходит значительное изменение микрорельефа поверхности частиц песка с развитием микропор. Установлено, что достижение массовых долей алюминия и железа в кварцевом песке порядка 11,78 и 7,11 % является индикатором предельной выработки адсорбционной ёмкости фильтра и обоснованием для планирования его замены.Предложенный подход позволяет осуществить переход от календарного регламента к прогностическому управлению сроком службы фильтра, а также обеспечивает предотвращение превышения предельно допустимой концентрации загрязнителей в сетевой воде и оптимизацию затрат на водоподготовку.</p></abstract><trans-abstract xml:lang="en"><p>The paper considers the investigation of quartz sand as a filter material for water treatment systems of heat supply installations and to the development of quantitative criteria for forecasting its service life. The quartz sand filter is transformed into a composite material covered with aluminum and iron oxides, which are formed because of adsorption and deposition of ions from the source water during operation.With the methods of electron microscopy and energy dispersion analysis it has been found that when a filter is operated on source water with an Al ≈ 0.58 mg/l and Fe ≈ 0.44 mg/l, there is a significant change in the microlattice surface of the sand particles with the development of the micropore. The authors established that the achievement of mass proportions of aluminum and iron in quartz sand of the 11.78 and 7.11 % order is an indicator of the maximum capacity of the filter adsorption and a justification for planning its replacement.The proposed approach enables a transition from a calendar‑based maintenance schedule to a predictive management of the filter’s service life, prevents the exceedance of permissible concentration limits of contaminants in network water and the optimization of costs for water preparation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>водоподготовка</kwd><kwd>кварцевый песок</kwd><kwd>фильтрация</kwd><kwd>адсорбция</kwd><kwd>растровая электронная микроскопия</kwd><kwd>энергодисперсионный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>water preparation</kwd><kwd>quartz sand</kwd><kwd>filtration</kwd><kwd>adsorption</kwd><kwd>raster electron microscopy</kwd><kwd>energy dispersion analysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бондаренко С.
