PROCESS FOR PURIFICATION OF LIQUIDS AND FILTERS FOR CARRYING OUT THIS PROCESS (VARIANTS)

摘要

The invention relates to the process of liquids purification from suspended particles and to the filters for the implementation of the process (variants). The object of the invention is use of ecologically clean material and as a tail receipt of ecologically clean production particularly in food industry as well as the possibility of multiple use of filtration material. The another object of invention is to draw up filters with comparatively large ability of dirt absorption which can be used in food industry. The above mentioned object is executed by filtration of liquid through tuff using of the cartridge filter type, so depending on content, volumes and purification level of liquids to be filtered the cartridge filters are used which have filtration element made of tuff fragment or tuff reduced fragments placed in framework consisting of internal and external nets.
