Изобретение относится к получению гранулированного фильтрующего материала и может быть использовано в технологии очистки природных вод для хозяйственно-питьевого водоснабжения и очистки сточных вод в фильтровальных сооружениях. Способ позволяет получить гранулированный фильтрующий материал, обеспечивающий высокую очистку воды от гумусовых, взвешенных веществ и ионов тяжелых металлов путем введение в глинистую суспензию порошкообразного доломита с последующей ее грануляцией и обжигом. Добавку вводят в количестве 15 - 18% от массы глины, а обжиг осуществляют при 800 - 880oС. 5 табл.The invention relates to the production of granular filter material and can be used in the technology of natural water treatment for drinking water supply and wastewater treatment in filter facilities. The method allows to obtain granular filter material that provides high water purification from humic, suspended substances and heavy metal ions by introducing powdered dolomite into a clay suspension with subsequent granulation and firing. The additive is introduced in an amount of 15 - 18% by weight of clay, and firing is carried out at 800 - 880 o C. 5 table.
