WebThe grain size distribution of DSs generally classifies them as fine soils, mainly within the silt range (0.002 mm < SD < 0.075 mm). The presence of diatoms (frustules) leads to an increase in the liquid limit (LL) [ 32, 40] and plasticity index (PI) [ 12 ], simultaneously with an increase in the effective friction angle (ϕ′) [ 18, 42 ]. Websuspended solids from fluids. The shape and the suitable grain size are the two important characteristics to achieve optimum cake permeability. The mean particle size of diatomite for filter aid is 7.6 and 9.8µm . The irregular shape of the fine particles is interlocked in such a way to give up to 90% porosity.
