[en] Sewage sludge treatment involves multiple operations and phase changes, with convective drying being the most energy-intensive process. This study explored the impact of the textural and viscoelastic properties of dehydrated sewage sludge (DSS) on its drying behavior. Samples were conditioned with different coagulant and flocculant doses, filtered under varying pressures, and convectively dried at 90°C. Results showed a strong correlation between storage modulus (G') and total solids content (TSC). Additionally, higher G' values led to increased evaporation rates. These findings suggest that viscoelastic properties can serve as predictors of drying performance, contributing to the optimization of wastewater treatment efficiency.
