3–13% are shown. In the case of titania slurry, however, it is contrary
to the normal observation. The flux remains almost unchanged up
to a solid content of as high as 24% (Fig. 8). This is again attributed
to its spindle-like particle shape, which provides less resistance
to water permeation as discussed above. This interesting observation
suggests that particle shape is an important parameter to be
considered for optimizing a washing proces
