Abstract
In order to facilitate the comprehensive reuse of the filter mud from sugar mills, the experiment of dewatering by expression of the filter mud was performed to investigate its dewatering properties. The results showed that the expression pressure has a significant effect on the dewatering properties. The moisture content of the filter mud decreased significantly as pressure increased in the lower range, and gradually became equilibrium in higher range. During the expression, the moisture contents of the mud decreased dramatically at the beginning, and then approached equilibrium. A simplified model is established for pre-dicting the variation of moisture content of the filter mud with time. The developed model has a good agreement with the experiment data.
