Hydrodynamic Study and Influence of Physicochemical Parameters on Gas Retention in a Submerged Membrane Bioreactor
Author(s): Nsoe MN*, Kofa GP, Marc H, Ndi KS and Kayem GJ
Gas-liquid reactors present transfer difficulties due to diffusion effects. It is necessary to master the aeration and
hydrodynamics of the medium to conduct a better reaction and performance. For this purpose, a study in a
submerged membrane bioreactor was been conducted. Gas retention was measured by the manometric method. The
experiments were carried out at different temperatures; 25°C and 45°C, with a variable airflow rate of 3 to 16 mL/S
and different solutions (osmosis water, ammonium formate solution, ammonium formate+salt solution, synthetic
rubber effluent). The results show that gas retention increases with aeration rate and temperature. On the other
hand, the more the medium becomes rich in organic substances, the more the gaseous retention decreases. The
homogeneous fine-bubble regime is obtained for an airflow rate ranging from 3 and 10 mL/S o.. View more»
