In the literature the organic coagulants and flocculants products are easier use with weak dose than inorganic salts, commonly used for coagulation and flocculation. Even if, it is more expensive, this doesn't modify the characteristic of sludge such as pH or alkalinity, which were not studied here [6].

The main goal of sludge thickening is to reduce the sludge volume by removing as much as possible of the water contease of the solids content of sludge. Thickening is achieved by the following three methods:- a) Gravity thickening:- Gravity thickening is achieved in circular tanks similar to sedimentation tanks.
