Hydraulic and filtration studies of updated column-absorbers and their parts

Abstract

Developed: hydraulic desk for hydraulic and filtration test of water absorption devices; tested: improved models of column absorbers and their parts of actual size. Hydraulic study evidenced that drain-pipes subject to the diameter carry 4 through 22 L/s across the bottom filter. Filtration study evidenced that the capacity of column-absorbers depends mainly on penetrability of fill filter of the upper cell, water intake area of the mean cell and water stratum on land surface. Hydraulic and filtration model study updated basic parameters of the low and mean cells of three types of the constructions subject to the features of the upper cell. The investigations determined penetration capacity of filter column absorbers: 0/22 L/s (FCA-1); 0.45 L/s (FCA-2); 0.71 L/s (КПФ-3).
