FIELD: process engineering.SUBSTANCE: invention relates to treatment of household and industrial effluents. Water filtration module comprises bed, drain-distribution system composed of perforated tube provided with porous cartridge made from fibrous material to cover perforated tube surface, and connection elements. Said perforated tube has different-diameter air and water feed holes. Water feed hole diameter makes two air feed hole diameters. Spacing between air feed holes makes two spacings between water feed holes. Design area of perforated tube holes is governed by the following relationship: S=[(n×0.785×d?)+(n×0.785×d?)]×k, where n, nis the quantity of air and water system holes; d, dare diameters of air and water system holes; k. is porosity factor.EFFECT: higher efficiency of filtration.2 dwg |
