FIELD: technological processes.
SUBSTANCE: invention relates to water treatment and purification methods and can be used in food industry, medicine, pharmacology. Method of heat-resistant cartridge making consists in that from crude refractory, for example, ceramic, porcelain, earthenware mixture or clay containing organic inclusions uniformly distributed throughout volume, layer by layer forming cartridge with cylindrical wavy filtering surface or tubular shape, wherein each layer is formed alternatively. After each molding operation performing drying and annealing with increase of drying time and with low heating temperatures gradient during annealing. In process of annealing organic inclusions are burned making combustion products, which, while exiting outside, determine cartridge water permeability.
EFFECT: increasing filtration quality and throughput.
