SUMMARY

The discussion focuses on measuring biomass yield in a non-homogeneous anammox bioreactor, specifically one where biomass is concentrated at the bottom. Techniques suggested include agitation to create a more homogeneous mixture, with considerations for shear stress during agitation. Additionally, ultrasound depth measurements, akin to "Fish Finder" technology, are proposed as a potential method for quantifying biomass without altering the reactor's conditions significantly.

PREREQUISITES
  • Understanding of anammox bioreactor operations
  • Knowledge of biomass measurement techniques
  • Familiarity with agitation methods and their effects on shear stress
  • Experience with ultrasound measurement technologies
NEXT STEPS
  • Research agitation techniques for bioreactors, focusing on low shear methods
  • Explore ultrasound measurement applications in bioprocessing
  • Investigate the effects of mixing on biomass yield in anammox systems
  • Learn about continuous bioreactor sampling strategies
USEFUL FOR

Researchers, bioprocess engineers, and laboratory technicians involved in the operation and optimization of anammox bioreactors and biomass measurement techniques.

We have in our lab a continuous anammox bioreactor, however, it is not well mixed, i.e. all the biomass is concentrated at the bottom of the reactor. We're interested in quantifying the biomass yield. Does anybody know of any techniques to measure this in a continuous non-homogeneous bioreactor? Thanks!

Agitate it? Then it would be a homogeneous bioreactor, and you could easily pull out a sample. If shear is a problem, know that agitation can be low shear or high shear or in between.

Would the biology work better or worse if the reactor was agitated? If worse, maybe you could just agitate it when you needed to pull a sample.
 
Ultrasound depth measurements, similar to a "Fish Finder" as used on fishing boats.
