The purpose of this study was to design and examine porous ceramic materials on the basis of diatomaceous earth, as well as carrying out preliminary model researches of the purification of drinking water. The conditions, parameters and methods of production of the ceramic samples have been selected on experimental way, in order to characterize them by suitable porosity and tensile strength. The authors have searched such porous ceramic materials, which exhibit positive charge, in contrast to viruses, which have a negative surface charge in pH o drinking water.
