The Removal Efficiency of Dichloromethane Vapors by Biofiltration on Various Packing
https://doi.org/10.18412/1816-0395-2015-5-20-25
Abstract
The results of comparative tests of various types of packing for biofiltration of dichloromethane vapors (a combined packing made of polymer materials, regular
packing made of polyurethane foam and coal grains 3–4 mm in diameter). Packing were compared by their geometric, hydrodynamic, and mass-exchange characteristics.
In addition to the influence of properties of packing on the biofiltration efficiency, the influence of organization of the contact between interacting
gas–liquid flows (co-current and counter-current) is considered. The experiments were performed in laboratory bioreactors 40 mm in diameter. The influence of
geometric properties of packing on the biofiltration efficiency is revealed and confirmed experimentally. The variation in the pressure loss in the packing layer in
time is established.
