Изобретение относится к целлюлозно-бумажной промышленности, к производству фильтровальных материалов для очистки различных жидких и газообразных технологических сред. Первый слой предлагаемого двухслойного фильтровального материала предназначен для механического удержания частиц загрязнений из фильтруемой среды и состоит из целлюлозы и диатомита, а второй слой - для удержания растворенных веществ, поэтому обладает сорбционными свойствами и содержит целлюлозу и активный уголь.The invention relates to the pulp and paper industry, to the production of filter materials for cleaning various liquid and gaseous process media. The first layer of the proposed two-layer filter material is intended for the mechanical retention of contaminant particles from the filtered medium and consists of cellulose and diatomite, and the second layer is for the retention of dissolved substances, therefore, has sorption properties and contains cellulose and activated carbon.
