摘要：One of the most important technological processes of water treatment is the process of filtration.Scientists and producers keep on searching new filtration materials which allow for better water purification, are simple in exploitation and do not add chemical substances to the treated water.Therefore, the aim of the present study was to analyze physical and chemical parameters of two unknown porous masses X1 and X2.Such physical parameters as color, granulation, bulk density, the equivalent diameter, the coefficient of uniformity and the porosity of the material were measured and determined.Additionally, the possibility of water treatment was studied during the filtration process in the laboratory tests.Chemical parameters were examined in the water flowing through the mass, such as pH, conductivity and COD-Mn as a general indicator of the content of organic substances in the water.Both studied porous masses were characterized by uniform size of particles.But they were not efficient enough in satisfactory reduction of oxygen consumption.Mass X2 slightly better adsorbed organic substances.It was found that the tested unknown mass filter slightly increase the pH of the filtered water.
