Otherwise, steam pressure filtration is applied as a new method allow improve the dewatering efficiency and reduce the cracking. Countermeasures are suggested to prevent the probability and degree of cracking on filter cake. Almost the mechanism of cracking is assumpted and proved. Otherwise, saturation and residual moisture content on filter cake are also calculated to evaluate the extent of dewatering. Permeability ratio is used as the relevance output parameter to quantify the degree of cracking. Experiments are executed by changing parameters like solid volume fraction of initial suspension, the height of filter cake and the applied pressure difference using the conventional pressure filtration. They are both fine materials, which negatively affect the filtration process.
