Abstract :
[en] This paper investigated the influence of dual conditioning of waste water treatment sludge on the evolution of sludge internal structure during convective drying. Results showed clearly an impact of chemical conditioners on the evolution of the created porosity. For sludge flocculated by single conditioning, a centred porosity delimiting by external crust was shown, while for dual conditioning, a porosity structured in lamellae, was identified.
