Sparged gas
Web1. apr 2009 · In addition, the gas sparging and agitation rates are restricted to low levels because animal cells are very sensitive to shear stress and are easily damaged 9, 10, 11, 12. These restrictions induce dCO2 accumulation in large bioreactors. WebThe Air Sparged Hydrocyclone (ASH) was designed to enhance collisions of mineral particles with sparged gas bubbles and on this basis specific capacities of as much as 100 times those of traditional flotation equipment were achieved. We will describe modifications of the ASH, which have enabled us to apply it in wastewater… cleanwatertechnology.com

WebSparging involves passing finely dispersed gas bubbles through the liquid. This helps to improve mixing and increase the surface area for gas-liquid mass transfer. Consequently, … WebIn this case, sparged gas bubbles should be large enough to travel through the bioreactor bulk liquid to the culture surface, where the absorbed CO 2 can be released into the headspace. Bubbles that are too small might dissolve in the liquid before they have reached the headspace, with no net removal of CO 2 from the culture.

WebDuring the first experiments, argon gas was sparged through the system for mixing and inhibition of growth was observed. Experimental results indicate that the stripping of carbon dioxide from the culture liquid caused this inhibition of growth. Possibly, the Rhodopseudomonas sp. used requires carbon dioxide during growth on a highly reduced ... harvard business packet loginIn chemistry, sparging, also known as gas flushing in metallurgy, is a technique in which a gas is bubbled through a liquid in order to remove other dissolved gas(es) and/or dissolved volatile liquid(s) from that liquid. It is a method of degassing. According to Henry's law, the concentration of each gas in a … Zobraziť viac Solvents used in high-performance liquid chromatography (HPLC) are often sparged with helium.
