title: SUBSTANTIATION OF FILTER-SORPTION LOADING EFFICIENCY DURING UNDERGROUND WATER PURIFICATION
abstract: The aim of the study was to determine the effectiveness of groundwater treatment through filter-sorption loading by choosing the optimal ratio of its components and loading height. Material and Methods: the rounded (natural) quartz sand with a particle size of 0.8–2.0 mm and activated carbon on a coal-mining basis with a particle size of 1.5–2.8 mm was used as components of the filter-sorption loading in the given studies. During the research various ratios of these components with different loa
