Improved Fermentation Process For Producing Methane From Cheese Whey, Abdulraman Y. Awad
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Two methods of single-stage fermentation were used to produce methane from whey. The first method involved batch fermentation in which the pH was automatically controlled at 7.0. In addition to pH control, the second method was characterized by introducing the substrate continuously into the fermenter along with dilution water to keep the organic acids at a non-toxic level.
The first method did not improve the production of methane compared to the batch fermentation in which a pH control system was not used (41). However, the second method showed that the concentration of organic acids has a major effect on limiting …
