ABSTRACT
Sludge solids contain a large fraction of volatile solids or rich in organic content, which makes it easily decomposable, putrescible or unstable. Hence, sludge stabilisation is necessary, otherwise it will be full of nuisance value or a potential case for putrefaction. Thus, sludges are stabilised to:
Reduce pathogens,
Eliminate offensive odours, and
Inhibit, reduce, or eliminate its potential for putrefaction.
