4. Summary
A mathematical model based mainly on the amount of elements (magnesium,
sodium, calcium) in the mixture was presented in this paper. All
previous factors, which were included in the further version of the
model 22, were also included. The following
conclusions can be drawn on the basis of the analysis and verification
of the developed mathematical model:
- The verification of the new equations showed that the developed model
is suitability for the prediction of methane yield in the processes of
fermentation agricultural substrates. This suitability works with good
results under laboratory conditions as well as in agricultural biogas
plants applying the continuous technology.
- The analysis of the impact of magnesium sodium and calcium showed
influence of this elements on methane yield.
