Modeling of Thin-Layer Drying for Dewatered Sewage Sludge

Experiments on the moisture analyzer for thin layer dewatered sludge drying are presented in this paper. The sludge drying rate of different temperature and thickness a reinvestigated. The model basing on the drying characteristic curve is adopted to simulate the drying rate evolution as a function of water content and the results show that the model could be used to evaluate the thin-layer drying process of dewatered sludge.
