Dear all,
I am working in biotech industry & would like to know how vvm of air is calculated. Please do needful.
Thanks in advance.

Till date no one has given any comment on my query? Is anybody capable to explain my query?
VVM…Vessel Volume/Minute.
I’m not 100% sure what the question is.
eg. If you have a 1000 liter fermenter, with 600 liters of liquid broth…1 VVM would be equal to 600lpm of air flow via Air rotameter. 1.5 vvm = 600x1.5…etc etc.
Does this help?
dear friend,
vvm can be varied from capacity of fermenter: and is absolutely measured using rotameter. And vvm also depends on the nature of broth using in the fermenter (cultrue growing in fermenter).
