Volumetric gas-liquid mass transfer coefficients in a rectangular bubble column with a rubber aeration pad

Overall volumetric mass transfer coefficient in a modified reversed flow jet loop bioreactor with low density particles

“…A batch of liquid, of volume nearly equal to that of reactor, was deaerated to approximately zero oxygen concentration by rapid addition of 300 g m-3 of sodium sulphite (Na2SO3.7H20) together with 2 g m -3 of cobaltous chloride (CoClz. 6H20) for a few minutes [16]. Air flow to the reactor was started at a pre-set value.…”

Characteristics of three-phase internal loop airlift bioreactors with complete gas recirculation for non-Newtonian fluids

“…A transient gassing-in method was used [17]. Water of nearly equal volume to that of the bioreactor was deaerated to approximately zero oxygen concentration by rapid addition of 160 mg/L sodium sulphite and 2 mg/L cobaltous chloride [18] before each measurement. Because the sulphite concentration is very low, one assumes that C * is constant and the effect of chemical acceleration on O 2 -transfer is negligible.…”

Characterization of gas transfer and mixing in a bubble column equipped with a rubber membrane diffuser

“…Deckwer's group also noticed that, with this rubber plate distributor, clogging was avoided because of its elastic properties. Medic et al (1989) used a ''perforated rubber aeration pad'' in a bubble column with a 2-m 2 crosssectional area and from 2 to 5 m of liquid above the membrane. The aeration pad made from reinforced rubber of 1.5 mm thickness with 4 holes ⅐ cm −2 (1 mm approx.…”
