Abstract:
1. Process for modifying the structure of an organic sludge to be subjected to drying, comprising a step in which said organic sludge, being in the form of a wet solid with a content of dry matter equal to or higher than 20% by weight of the total weight of the sludge, is exposed solely to the action of an electric field generated by direct current, which is comprised between 40 V/0.01 m and 100 V/0.01 m, wherein said electric field is generated by a positive pole and by a negative pole between which said sludge is fed in a continuous manner, wherein said positive pole and said negative pole consist of a first plate and of a second plate separated by an insulating element, defining a tubular body having an inlet opening and an outlet opening for said sludge, wherein said sludge, following said exposure to said electric field is subjected to a drying step.
