Choice of mass exchange apparatus for groundwater deironing

Abstract

The absorption of air oxygen by water in the horizontal absorber with bucket-shaped dispersants (HABD) and the vertical apparatus with a continuous bubbling layer (VABL) was studied. It is shown that these processes occur according to the law of First-Order Reactions. It was found that the constant absorption rate is 46.5 times higher in HABD than in VABL at a gas content of 0.05 and a bubble diameter of 0.002 m. It is recommended to use the VABL device for water deironing at pH <6, and for pH greater than 6.0 - HABD.
