Abstract
In the article, the process of water purification mainly from suspended particles of clay mineral saponite is considered. Those particles are formed during the process of diamond mining in the quarry water of M.V. Lomonosov Mining and Processing Plant owned by PJSC «Severalmaz». The scheme of the existing technology of sedimentation of suspended particles using the acoustic method is shown. Using the granulometry method the size of suspended particles in free volume was studied, and the sedimentation rate of suspended substances was calculated using Stokes' formula. The mineral composition of suspended particles in the quarry water is determined using Х-ray phase analysis. Calculations of the sedimentation rates of suspended particles are given for aluminum sulfate – traditionally used in water clarification – and for calcium-aluminosilicate reagent developed when taking into account the mineral composition. The results of measurements of pH of the clarified water, the content of residual aluminum, and the indicator of turbidity of the water are shown
