Bacteria have to adapt to changing conditions in animal waste during anaerobic digestion. The presence of liquid and solid substances in the waste causes this. When a straw residue layer forms, it has negative effects. It reduces biogas release, methane concentration, and the quality of the sludge. It also increases the time the substrate spends in the bioreactor. The substrate is initially ground and cavitated, which changes the particle structure by creating micro-cracks. This reduces temperature differences and ensures equal load on the biocenosis. It also maximizes contact with bacteria and releases natural enzymes, which act as biological catalysts to enhance fermentation in a bioreactor. A macerator, geterorotor pump, and cavitation dispersant are used in a new technology, developed through analysis, to grind particles as large as 2.5mm and homogenize them to micron size using screw and knife devices. Mathematical models in this article describe substrate processing (screw/knife grinding, dispersion, homogenization) to optimize anaerobic fermentation in a bioreactor. Using known theoretical and experimental parameters, the authors derived the mathematical model through numerical methods. We used Mathcad simulations to get the operating parameter results for the processes, then tested these in SCADA Trace IS Mode 6.10.1.
