A method of purifying water includes sprinkling of initial water on the surface of the upper unsubmerged part of granular layer followed by filtration through a lower submerged part of the granular layer and overflow from it into a sub-filter space. Unsubmerged and submerged parts of the layers are in dynamic equilibrium, which depends on the mass of retained impurities, physical properties of the grains of filtering layer, velocity of filtering flow, parameters of the impurities in the source water and duration of filtration.
