Abstract :

A mathematical model was conducted to describing the main microbial processes, occurring in the UASB reactor leading to the production of biogas from dairy waste water. In the model, the UASB reactor is divided in four well-stirred reactors coupled in series and it comprises substrate degradation, biomass growth and death with time and the washout of microorganisms, the reactions that take place within the granules. The important outline of the paper is the development of a UASB reactor model taking into account the mass balances for substrate degradation and microorganisms growth. The simulated results of UASB reactor treating dairy wastewater were found to be in good agreement with the experimental results.This model is a useful tool in the optimization and development of UASB reactors.
