Abstract (2. Language):
This paper describes technological possibilities to
enhance methane production in the anaerobic stabilisation of
wastewater treatment plant excess sludge. This objective can
be achieved by the addition of waste residues: crude glycerol
from biodiesel production and residues from fishery. The
addition of glycerol in the amount of 2–5% by weight causes
the enhancement of methane production of about 250–400%.
At the same time, the percentage increase of total solids
concentration in the outgoing sludge is ten or more times less.
The content of methane in biogas is higher in the case of
admixed substrate.
