ABSTRACT: The Anaerobic digestion in Senegal is of particular interest to the
scientific community given the availability
of substrates and their distribution throughout the country. However,
from a technological point of view, the existing installations seem to be
obsolete, which does not allow to reproduce the results of the laboratory
tests. Thus, the present study aims to take stock of the situation in relation
to the studies carried out in laboratories and those concerning the actual
monitoring of the bio-digesters in situ. In fact, most experimental
bio-digesters operate under optimal implementation conditions with strict control
of input and output parameters. However, this is not the case for reactors
installed in the field, as these so-called bio-digesters are exposed to real environmental conditions with a periodic
variation of the physic-chemical parameters in the reactors throughout
the day. This leads to a differential behavior of the micro-organisms, thus
affecting their performance. This results in lower yields for those digesters
operating under real environmental conditions.
