Matviyenko O. Defluoridation of ground waters on the filters with the modified loadings

On the basis of detailed research of chemical structure and physical-chemical properties of ground water with great content of fluoride the technology of their treatment is developed. It is marked, that known methods are ineffective and demand significant expenses for reagents and for the power supply. With the purpose of increase of efficiency of defluoridation of ground water with filtration through the natural zeolite which modified by the hydrooxysulphate of aluminum. The suggested method is based on cation-exchange properties of natural zeolite consequently compounds of aluminum are strong attaching on the surface of grains of loading. In work the mechanism of process of defluoridation of ground water on various loadings is investigated, technological parameters of process are established.
