摘要：
Dead-end inclined ultrafiltration is examined, using a dynamic membrane comprised of fine particles formed on the microfiltration membrane by dead-end downward filtration. The formation behavior of the dynamic membrane is described by the cake filtration rate equation in which the compressibility of the cake is taken into account. A dynamically balanced rate of filtration can be obtained by the inclined ultrafiltration technique, because the growth of the gel-cake can be significantly suppressed. If the membrane is inclined before enough cake to be exfoliated is formed, the dynamically balanced filtration rate is not influenced by the time when the membrane is inclined.
