Quarry wastewater is the main pollutant for the surface and underground natural water bodies during mining operations. Negative impact is expressed in contamination of natural reservoirs with fine suspended particles and salt solutions. To reduce the harmful impact of quarry wastewater they are treated using artificial filtering massifs. Such massifs are commonly constructed using artificial and natural sorbents. The retention of particles in the filtering layer is the result of two main processes: the adhesion of fine particles of suspension to the surface of the particles of the artificial filtering massif and the jamming of coarser particles in the pores of the filter layer. Simultaneously with the processes of contaminants capture, the process of contaminants washing out of the filter array may occur. It occurs when the particle size distribution of the filter layer is unappropriated and filtration speeds are high, and may be accompanied by deformation of the filter media.
