Management of sludge produced within wastewater treatment plants has become a key issue. After thickening, the removal of remaining water using mechanical dewatering and/or thermal drying is essential before any type of valorisation. Polymers are usually employed in the conditioning step in order to promote particle aggregation, making the dewatering easier. In this work the impact of the polymer dosage and nature on dewatering and convective drying of sludge is studied.
