The aim of the study was first to develop a simple and practical model of anaerobic digestion including sulphate-reduction in anaerobic ponds. The basic microbiology of our model consists of three steps, namely, acidogenesis, methanogenesis, and sulphate reduction. This model includes multiple reaction stoichiometry and substrate utilization kinetics. The second aim was to determine some kinetic parameters associated with this model. The values of these parameters for sulfidogenic bacteria are used in the anaerobic pond model to describe the sulphate reduction processes and to evaluate the risk of odour generation. [less ▲]

One of the most known disadvantages of the technique of lagoon is the generation of smells, often associated with the presence of hydrogen sulfide (H2S), itself generated by the process of sulfate-reduction. In this paper, we have built a stoichiometric model of sulfate-reduction by providing balanced equations against the elements, electrons, charge and energy. In our model, sulfate acts as an electron acceptor and organic compounds such as lactate, propionate, butyrate, ethanol and acetate are in turn sources of carbon and electron donors. This model allows to quantify the production of sulfide and predicts the variation of alkalinity during the process of sulfate-reduction. [less ▲]
