Lesson 2 of the four training sessions on "Common Process Challenges in Anaerobic Digestion". We can adopt two popular methods to address the challenges encountered in the previous lesson: batch and continuous fermentation testing. Although the purposes and applications of these two tests are different, they both simulate anaerobic digestion processes on a smaller scale. Let's take a look at the working methods of batch processing and continuous testing, their roles, and the advantages and disadvantages of each method.
