The use of ceramic filter elements for water purification is promising due to the availability of raw materials, simple production technology, long service life, resistance to fouling and aggressive chemicals, as well as the possibility of thermal regeneration. These advantages allow us to consider ceramics as an alternative to their polymer counterparts.
	The basis for the production of filter ceramic materials are aluminosilicates. The study considers the use of basic components of diatomaceous earth and kaolin, anti-shrinkage, glazing, pore-forming and other components. The process of wet and dry sintering of the mold was investigated and thermal analysis of the mixture was performed to assess the course of processes during sintering of the sample. 
	The obtained material is able to effectively reduce water turbidity to WHO standards, even at abnormal levels (up to 30 NTU) [1].
	The prospect of further research lies in the study of the properties of the filter material in complex natural waters, the study of the regeneration process and chemical and physical resistance to external influences.
