Abstract

1. Process for the pre-treatment of sludges for improving their flocculation and/or dewatering behaviour in a subsequent dewatering apparatus, in which optionally polyelectrolytes are added as flocculating adjuvants, characterised in that the sludges are concentrated to a percentage of solids of at least 5% by weight, that prior to mechanical dewatering liquid combustible organic additives such as oils, particularly waste oil, are added to the sludge to be dewatered in an amount of from 0.5 to 50% by weight in relation to the percentage of solids of the sludge, and that in addition to the liquid combustible organic additives oxidizing agents, particularly hydrogen peroxide, oxygen or air, are added.
