Oxygen transfer rate and oxygen uptake rate in bioreactors

- This video follows from the short introduction to bioreactors and the video detailing agitation, mixing, and how to select the appropriate impeller type in bioreactors.
Bioreactors are different from traditional chemical reactors; because the catalyst used in there is "alive"; therefore, it is important to keep strict control over the conditions in the reactor. Sparging of oxygen in many cases are necessary; we will discuss oxygen transfer and uptake rate which are important design parameters. Furthermore, we will show how to improve this and some basic calculations you can do.
Thank you for your lectures, I'm enjoying them as a student who studies bioprocess!
Glad you like them! Let us know if you have any topics related to bioreactors you would like to learn more about as we are keen to expand on these videos.
Dank Je well!!
Graag gedaan!
Could you please insert the link here for the bioreactors lesson 1? I cannot find your second lecture, it would be really useful.
The link to the first video is here: ua-cam.com/video/dvh2jPvAa-Q/v-deo.html. I think you make a very valid point, I have now created a playlist with the order you should watch the bioreactor videos in. This is more of an introduction and I will make a separate playlist with more specialised topics (such as perfusion reactors etc)
@@MarloesPeeters thanks so much for the quick response 🙏
Thank you very much for this class Prof Peeters. I can learn a lot. I am working for my Ingennier degree research, is about automation of aeration systems for activated sludge bioreactor in wastewater plants. Can I send you a mail with questions?? Thank you so much! Grettings from Chile
Sure you can email me; I can see what I can do (wastewater is not my expertise)
5:45 why putting pure oxygen puts the system in explosion ,?
If pure oxygen is being used for aeration, there is an increased risk of spreading a fire due to an oxygen-enriched atmosphere. Usually air, rather than pure oxygen, is used for aeration (this is also much cheaper, which is the main reason it is used)
Your videos are awesome! Congratulations and thank you for the great explanation!
That is such a big compliment, many thanks!
